Is it dangerous to water plants with cold water? Why is it not recommended to water indoor plants with cold water? Is it possible to combine watering with fertilizing?

From the willow
Irrigation is one of the main methods of treatment. Even the most carefully fertilized and nurtured plants will not grow well, water your plants if you do not provide them with the required dose of water. A lack of water will make the plants squiggle less, increase their susceptibility to disease, and most of all - they will not look beautiful. It is true that the need for watering our garden can be significantly reduced accordingly, so that the garden imitates natural environment a habitat. However, the majority ornamental plants, varieties available in nurseries are selected, why plants that require regular watering are watered, especially during periods of drought, not to mention the fact that a lawn without proper watering quickly loses its decorative appearance.

How often should I water my garden plants?
How to properly water from willow.
The frequency of watering depends on many factors, including the time of year, why the plants are watered, weather conditions and requirements specific types(among species garden plants we find that periodic water shortages are eliminated quite well). Newly planted plants have a much higher demand for water resources than whether it is possible to water plants that are already well rooted. It also depends on the reach of the root system - the greater the surface area from which the plant takes water. Thus, why do you water the soil abundantly before transplanting plants? perennials and annual plants suffer more quickly from lack of rainfall, can plants be watered and should they be watered more often than plants. In turn, a tree whose root system ascends into the soil absorbs water from deeper layers; the tree grown in this way, as a rule, does not need watering, how to water houseplants except during periods of extreme heat and drought.

Why do you water the soil abundantly before transplanting plants?
Regardless of the age and type of plant, watering should begin even before the leaves lose turgor (it stops being hard and dries out). Therefore, it is best to monitor the state of soil moisture - when the soil dries to a depth of several centimeters, they begin to water, how to water indoor plants, why, before replanting plants, the soil is watered abundantly, without waiting for the moment when the consequences of water deficiency will be reflected in the appearance of the plants.

Let's remember that plants do not need watering every day, on the contrary - too frequent irrigation can cause a lot of harm, which is why it is not recommended to water plants with cold water, as in the case of failure of this treatment. The principle should be better to water less often and more than the other way around. For irrigation to be more efficient, it is necessary to reduce the evaporation of water from the soil surface by mulching, which plants are watered, for example. Bark or gravel. Remember also that bare soil evaporates faster - so it's worth introducing ground cover plants into the garden.
When to water plants
why it is not recommended to water plants with cold water.
Garden plants are watered early in the morning or in the evening. This should not be done during the day, especially on sunny, hot days - droplets of water remaining on the leaves concentrate the sun's rays, which plants are watered, which leads to plant burns. In addition, plants heated by strong sunlight and watered with cold water experience heat shock, which can negatively affect their status.

How much water supply to plants
how to water plants correctly
It is worth repeating the principle of better watering plants less often and more. Each watering should be soaked in water, with which water to water the plants, the layer of soil that has the largest mass of roots - that is, to a depth of about 15-20 cm in the case of discounts, 30-40 for trees and shrubs, and also 15 cm in the case of lawn... Smaller, water only to moisten upper layer soil in which plants do not naturally grow roots. Typically this mistake is repeated and will cause the plants to begin to grow roots just below the soil surface as the plants are properly watered, which greatly increases their vulnerability to drought. Therefore, correct bottling of products is a time-consuming procedure.
Is it possible to water plants with water?
When watering trees and shrubs, remember that the bulk of the active roots go beyond the scope of their crowns; it is possible to water the plants with water, so there is no point in watering the soil next to the chest.
what plants can be watered
What is the best way to water the garden?

Certainly, huge help in garden care to install an automatic irrigation system. If we additionally install humidity sensors and an automatic programmer for which plants can be watered, this system will not only help us water the garden, but will also help us with this operation.

Those who choose the traditional method of watering should also benefit from a wide range of equipment that makes this maintenance procedure easier. First of all, it is worth investing in a good garden hose, it is best to choose one that is resistant to bending and twisting, which can be very inconvenient when we go from garden hose. In "traveling" with a kite, a big advantage is the use of a special night, or reel for reeling in a garden hose (some of which turn on the hose automatically).

how often to water plants

The need to carry a long hose can be completely eliminated by installing a so-called garden in some places. can water consumption - water is supplied through these pipes buried in the ground. Then only we have a short section of a garden hose, which is included in the “nest”, how often to water the plants, and after watering one part of the garden, move on to the next (a special valve is built that opens the water supply to a specific box when connected to the hose, and closes it after disconnecting ), This solution is especially convenient in large gardens that take a long time to move, and therefore the heavy, hose is cumbersome. How often do you water the plants.

Take the good end of a garden hose. Plants should be watered carefully, preferably with a mist of water; a strong flow can damage plant leaves and leaching the soil. In the garden practical advice Adjustable water spouts provide a powerful stream useful for other gardening tasks, such as cleaning garden surfaces or tools.

Why plants should not be watered with cold water
As already mentioned, a properly carried out watering operation should provide water to the deeper layers of the soil (at a depth of about 15-30 cm) in order to achieve this, each part of the garden should be watered for a long time - for large gardens it can take up to several hours. Therefore, to save time, why plants should not be watered with cold water, you can abandon the watering hose and use a static sprinkler. The choice of this type of equipment is huge. Depending on the shape of our garden we have a choice of sprinklers (irrigation area is incorrect, round shape) or swing sprinklers (which are especially good on square or rectangular shape). It is best to choose models with an adjustable range of power and flow, which will allow us to precisely regulate surface watering, and why plants cannot be watered with cold water, in this way we save water. Many models have a timer; all you have to do is set it correctly and turn it on.

why water plants
To receive a discount or next to a hedge must extend to the snakes perforated and penetrating. We can bury it in the ground (to a depth of 15-20 cm), or place masks on its surface, for example. A layer of mulch. This solution allows the most efficient use of water, why water the plants, as it is absorbed in close proximity to the roots of the plants, which significantly reduces evaporation. Another advantage is the fact that why water the plants, you do not get the plant leaves wet, which can contribute to the development of fungal diseases.

To prevent indoor plants from getting sick, to delight them with beauty and to purify the air in the room, they need to be properly cared for: watering, lighting, fertilizing. Why is it not recommended to water indoor plants with cold water? What will happen if the gardener does not follow this rule?

Most plants adapted to home conditions come from tropical countries, where they are naturally accustomed to being watered with warm rainwater. Caring for indoor flowers, it is important to continue to comply with this condition to preserve their vital functions. The same rule is true when growing from seed, and others.

What harm is caused to indoor plants when watering with cold water?

Water for plants is an important component that helps carry out all necessary physiological processes:

  • dissolves organic and chemical compounds;
  • promotes the absorption of soil solutions by plants;
  • evaporating from the surface of the leaves helps the flowers maintain the required temperature.

Understanding these transformations explains why it is not recommended to water plants with cold water: the processes of dissolution and absorption slow down or become impossible.

Experiments conducted by scientists have proven that a number of plants, when watered with warm water, develop normally and bloom faster:

  • pelargoniums;
  • gloxinia;
  • amaryllis;
  • hydrangeas;
  • hippeastrum, others.

If you water flowers with cold water, they weaken and begin to shed ovaries and buds.

At improper care in appearance healthy plants the leaves begin to wither, turn yellow and fall off, root system experiences shock and gradually rots. As a result, the flower may die.

In other plants, the foliage reacts sharply to improper watering: white or colorless spots and yellowing form on it. If the cause is not eliminated in a timely manner indoor flower may lose leaves altogether.

It is not recommended to water indoor plants with cold water because they do not dissolve well in it. useful material located in the ground. This prevents plants from receiving the nutrition they need. It turns out that there are enough useful elements in the soil, but they are inaccessible to the root system, and the plant starves.

What is the best water to water indoor plants?

Most best option– settled water room temperature. It is necessary to settle the water for 2-3 days so that the chlorine contained in it evaporates and the calcium and magnesium salts precipitate. An excess of these chemical elements adversely affects the growth and development of the plant, as it disrupts the absorption of iron, manganese, phosphorus, aluminum and other components by the root system.

It has the greatest softness rainwater, which can be collected in containers, brought to room temperature and used. It is important to ensure that water does not stagnate in containers for a long time. It is also recommended to mix clean rainwater halfway with settled tap water to eliminate excessive softness of the irrigation liquid.

Some gardeners adapt to freezing water in plastic bottles for 10-12 hours, then the separated non-freezing brine with impurities is drained, and pure ice thaw at room temperature. Melt or rain water contains fewer impurities than regular settled water, but provided that the grower lives in an ecologically clean area and the precipitation does not contain harmful chemical compounds.

It is clear why you should not water plants with cold water: it is very harmful for them. But warm water cannot be used either; a temperature only 2-3 0 C above room temperature is allowed. Warm water (above 40 0 ​​C) is used if necessary to stimulate plant growth.

About watering plants

It is with watering, a procedure so simple at first glance, that the most serious mistakes of amateur gardeners are associated, since plants suffer greatly from both excess and lack of moisture. But if you choose the lesser of two evils, it is always better to underfill than overfill.

Watering is a delicate matter. Plants need to be watered in such a way that they are sufficiently provided with moisture during the growth period and the earthen ball does not dry out during the dormant period. Learning to determine the water needs of each plant is your first task.

Since the need for moisture nutrition varies, only by observing each individual plant for some time can you determine when and how much moisture it needs.

Why do plants suffer from improper watering?

Strictly speaking, it is not the excess (or insufficient) moisture itself that is harmful, but its negative effect on the soil. The properties of the soil change: excess moisture increases its acidity, and a lack of moisture increases its alkalinity.

For example, cacti die not from excessive watering, but from high acidity soil formed from excess water supply.

If the plant does not have enough moisture, watering is irregular, then the numerous, most vital roots and especially the root hairs adjacent to the walls of the pot dry out and stop absorbing water. As a result, from lack of moisture, the leaves will become limp and drooping, and then completely dry out. Flowers wither and fall just as quickly.

With excessive watering, water clogs all the pores in the soil, and the root system becomes flooded. The roots stop breathing and die, and aboveground part the plant dries out because nutrients are not supplied to it.

How often should plants be watered?

Flower growers have several ways to check the pre-irrigation condition of the soil. Dry soil always lags behind its edge, and its upper layer is light.

For flowers growing in a cold and shaded room, it is recommended to carefully loosen the top layer of soil. Watering is needed if it has dried out by 1 - 1.5 cm.

How quickly the soil dries depends on the size of the pot and the composition of the soil mixture. The moisture reserve in smaller dishes is consumed faster than in larger ones. Therefore, plants planted in large containers are watered less frequently. More frequent watering is required for plants planted in ceramic pots(compared to plastic ones, with other care methods being equal).


Young, strong and healthy plants need abundant watering; weakened ones require careful, moderate watering. Plants with deciduous leaves require more moisture than evergreens.

During the period of strong growth, which is spring and summer, plants, with rare exceptions, are watered daily, and many species even 2 times a day (especially in hot weather). As growth weakens, moisture consumption decreases, and the plant needs it least during dormancy.

Seasonal differences in the watering regime are due to the different needs of plants for moisture during the growth and dormant periods. When watering during spring and summer active growth Plant mistakes made by gardeners are, firstly, rare, and secondly, most of them can be quickly corrected, since all plants need watering.

One should be careful: even a small mistake in watering in the autumn-winter season can become difficult to correct, or even completely disastrous. Thus, abundant watering of indoor crops at this time leads to impaired respiration of the roots, causing them to rot.

Starting in September, watering is gradually reduced, but with the inclusion central heating it is increased a little. It is very important to follow the rules of watering when the temperature drops during the off-season (second half of October), since the metabolism of plants at this time sharply decreases. And when vital processes are slow, the plant cannot accept and release water.


At low temperatures and abundant watering, the phenomenon of physiological dryness occurs: there is plenty of water, but the plant is not able to absorb it.

Spring watering should be increased with the appearance of the first leaf after winter. And be sure to reduce watering during cold weather in April - May, when the heating is turned off.

IN warm time The vast majority of crops are watered abundantly throughout the year. However, it is necessary to water not just all the crops, but each of them personally; for this you need to observe and know the characteristics of each. So, if the earthen lump of a palm tree and many other tubs begins to dry out, then the tips of their leaves become brown and dry.

You need to water the palm tree carefully, using a watering can with a long spout, so that the water does not get on the growing point, otherwise even with optimal mode watering the plant will dry out. This rule - do not pour on the growing point - applies to all plants without exception.

Watering hanging plants

Watering hanging plants has its own characteristics due to the fact that they are located much higher than other indoor plants, and their soil dries out much faster than, for example, those standing on a windowsill, since the warm air in the rooms rises.


How to avoid difficulties with watering high-lying plants? First, you need to buy a watering can with the longest spout. You can shoot once a week hanging pots and immerse in water so that the ground is saturated with moisture “with a reserve”, drain off excess moisture and return the plants to their height.”

In winter, hanging plants need to be sprayed frequently, since the air at the top is not only warmer, but also drier. Most convenient way To humidify the air around plants is to use a spray.

What kind of water should I water my plants with?

All gardeners agree that best water- rainwater, but indoor crops are watered with ordinary tap water. Snow water or water obtained from refrigerator ice is also used.

Tap water must be left for at least 24 hours in an open container and during this time poured into a thin stream 2-3 times so that it is saturated with oxygen and the chlorine evaporates from it.

As for boiled water, even experts have disagreements on this matter. Some advocate for it (mild), others are categorically against it (during the boiling process, the air necessary for plants is removed from it), others strongly advise watering it with water drawn from a tap with hot water(hardness is close to boiled). Therefore, it is up to you to decide based on your experience and practice.


Many plants are sensitive to both water hardness and high lime content. Optimal water (pH 5.5 - 6) with an excess of lime is obtained by filtering it through a layer of peat. To soften hard water, amateur gardeners add a few drops of phosphoric, sulfuric, hydrochloric or other acid to a bucket of water. However constant watering such water leads to acidification of the substrate. Do not soften water by adding sodium, which is toxic to plants.

Plants absolutely cannot tolerate being watered with too cold or too warm water. Watering with cold water is a direct path to root rot.

Water for watering plants during the period of strong growth and flowering should be 2 - 3 ° C above the room temperature, during the dormant period - only at room temperature, since watering warm can lead to their premature awakening.

The water must be clean, i.e. do not contain mechanical and chemical impurities. Some gardeners believe that "water waste" from the kitchen is ideal for watering. For example, the water left over from boiling potatoes contains starch that promotes growth. True, such a decoction is only suitable if it is not salted.

The same applies to the water in which vegetables were boiled. Settled mineral water(carbon dioxide free) can also be used for irrigation. And here soapy water It is strictly forbidden to water the plants.

How to water plants correctly?

With traditional watering from above, the stream of water is directed as close as possible to the edge of the dish so as not to wet the root. neck Therefore, it is better to use a watering can.

For abundant watering, when the entire first portion of water is absorbed into the ground, add until it flows into the pan. An hour after watering, the water from the pan should be drained.

It is recommended to water many crops from below, i.e. pour water into the pan, from where it is gradually absorbed into the ground. If the entire lump is wet and the surface of the soil in the pot becomes wet, watering is complete. If all the water is absorbed, but the soil above remains dry, then the pan must be filled with water again.

Saintpaulia, gloxinia and cyclamen do not like water getting on their leaves. They should be watered from below, immersing the pots in water up to about the shoulders until the top layer of soil in the pot becomes moist. Next, the pot is placed on a tray so that the glass excess moisture, and only after this the plant is returned to its permanent place.

This method of watering is also used for other crops when the dried soil does not allow moisture to pass through evenly.

IN summer time plants are watered in the evening, when they cool down after sunbathing, or twice - early in the morning and in the evening, in winter - in the morning.

How to correct mistakes made in watering?

If the soil mixture is very dry and is no longer able to absorb water poured onto its surface, you need to urgently place the pot up to its shoulders in a container of water until the soil on top becomes moist.

More often the opposite happens - plants suffer from excessive watering. At first, a “flooded” plant does not show signs of its painful state, but over time its leaves become lethargic, and if watering continues, they will fall off and the plant will die.

In case of waterlogging, the plant is taken out of the pot, and the rotten roots are cut off with a knife. The cutting areas should be sprinkled with crushed coal, allowed to dry, then the plant should be replanted in the soil mixture of the same composition, but with the addition of (up to half) coarse sand.

If you are away for a long time and there is no one to water the plants

Use a suitable method to gradually moisten the soil in your pots. If there are not many plants, rearrange them flower pots in a more shaded and cooler place in a wide container with water. Covering the soil with well-moistened moss gives good results for plants with moderate watering.

For compact plants, you can arrange a so-called “dripper”. To do this, leave a wet sponge or a plastic bag of water with the neck tightly tied on the surface of the earth in a pot, puncturing a small hole in it.


For a large plant in a large bowl, instead of a bag, use a plastic bottle with water, closing it with a stopper and making several holes near the neck. The bottle (2 - 3 bottles) is turned upside down and stuck into the soil. In this way, the plant can be provided with moisture for a week.

Currently, a special moisture storage device—hydrogel—is widely used. This is a kind of miniature sponge that looks like translucent granules: they absorb only 2 g and tenaciously hold up to 1 liter. water. When swelling in water, it’s a miracle - the granules increase hundreds of times, become jelly-like, while maintaining their strength.

With one-time watering, an earthen ball filled with hydrogel absorbs a truly huge amount of water, which it gives to the plant roots gradually, as if automatically maintaining optimal humidity soil.

During the process of swelling and evaporation, the hydrogel either increases or decreases in volume many times over, as a result the soil does not cake and remains loose and porous, breathable. And most importantly, the soil in the pot never dries out or becomes waterlogged, its humidity is always optimal, which is almost impossible to achieve

no other way.

Add granules to the soil in a simple way: use a pencil to poke several holes in the earthen coma along the edge of the pot and pour the granules into them. It is more convenient to mix them with soil for replanting plants at the rate of 2 g of granules per 1 kg of soil.


Particularly effective hydrogel with full complex fertilizers Plant roots, penetrating inside the jelly-like granules, long time supplied with water and all nutrients.

A one-time application of hydrogel is quite enough to feed plants for 3-4 years, and an overdose of fertilizers is not dangerous, since nutrition occurs only “on demand” of the plant, the rest of the nutrients are in reserve.

Plants (and seedlings) cultivated in a soil mixture with the addition of unique granules are watered 2-3 times a month, and the consumption of irrigation water is reduced by 3 times, since the useless evaporation of moisture is reduced.

Watering the garden with warm water is considered preferable to cold.

If you read various sources, then you can find a bunch of requirements for water - it must be warm, from a standing reservoir (not from a river) or settled, and you can also find advice on stirring it before watering in order to saturate it with oxygen.
Cold water in heat-loving crops slows down the development of the root system.
The most heat-loving ones are cucumbers, zucchini, pumpkins, squash, and melons. They are recommended to warm the water to 20 degrees.
Moderately thermophilic - beets during the germination period, tomatoes, peppers and eggplants.
I prefer water at 17-18 degrees. The allowed minimum is 12. And after cold nights you can support them with even warmer water - up to 25-27 degrees, it will help them survive the unfavorable external temperature.
In practice, not always and not everyone has the opportunity to water the garden with warm, settled water.
Therefore, you can find a bunch of opinions and evidence of how someone waters their garden with ice-cold well water and claims that everything is growing well.
I also don’t always have the opportunity to heat and settle the water, so I periodically water it with cold (not ice) water, and my water is river water (there is simply no other).
I primarily save the warm one for cucumbers and other pumpkin crops.
The second is for those crops that grow in a greenhouse. I water the rest with a hose.
I also try to water the planted seedlings with warm water only, so that they take root easier (if I plant them in warm weather).
Maybe I’m expressing a seditious thought, but from my own experience I came to the conclusion that watering time is more important than water temperature.
There is definitely no need to water in the middle of the day in the heat of the day.
It is necessary to water so that there is no excess dampness left on the leaves of plants overnight - this can really provoke the development of diseases.
Therefore, it is better to water the greenhouse and greenhouse in the morning, so that excess moisture leaves the air during the day, and the open ground by the evening, but so that the top of the soil and leaves have time to dry out before sunset, and the soil inside remains moist. Here you need to remember that warm water will evaporate faster and easier, but it’s better to water it with cold water a little earlier.

I agree that it is better to water with warm water, but if this is not possible, then it is better to water with cold water than not to water at all.

Properties and composition of water

Dissolved in water a large number of various salts that affect its characteristics, and tap water also contains chlorine, which is harmful to plants.

Water with a high concentration of salts is considered hard and requires purification., with a low concentration of salts - soft and can be used without prior preparation.

Water in pure form(distilled) can only be obtained by distillation, but most gardeners do not have access to this purification method and do not need it.

At home, water that is maximally purified from hardness salts can be obtained using a reverse osmosis filter (a filter operating on the principle of reverse osmosis).

Water acidity and methods for its correction

Tap water most often has alkaline reaction, which is suitable for a very limited range of plants. The acidity of such water must be adjusted, since most indoor plants require water of normal or slightly acidic reaction.

To acidify water, you can use substances that are found in every home:

  • Lemon acid;
  • Ascorbic acid;
  • Oxalic acid;
  • Vinegar (possible, but not recommended).

Water for irrigation without purification

Natural moisture is best suited for indoor plants: rain and melt water. Unfortunately, it is not always possible to collect water when it rains, and the amount of moisture obtained by melting snow is small.

In addition, in urban environments, precipitation is often too polluted by exhaust gases and other harmful substances. River and spring water may also contain large amounts of salts.

If you have an aquarium, you can use water for irrigation from it. It is much cleaner than ordinary tap water and contains small amounts of organic substances useful for the growth and development of plants.

Water temperature for irrigation

It is customary to use water at room temperature to water plants. However, it is better to water with water whose temperature is several degrees warmer than the air temperature.

Under no circumstances should you water plants with cold water., because sudden cooling of the root system can lead to leaf falling and root rotting.

Water purification

Tap water contains many impurities, and using it to water plants can be harmful. There are several methods for purifying water from chlorine and hardness salts.

Water purification from chlorine

The concentration of chlorine in tap water is much higher than the plant needs. Excess chlorine leads to yellowing of leaves, reduced plant growth and poor rooting.

The easiest way to remove chlorine is to let the water sit in an open container.. Wherein most of chlorine evaporates within 24 hours. You can also use special filters designed to remove chlorine from water.

Methods for purifying water from hardness salts

Pure distilled water is obtained by distillation, but this purification method is more suitable for laboratories than for home use. However, there are many simple ways purification of water from hardness salts.

Boiling

When water is heated, some of the salts precipitate, which settles on the walls of the dish or remains at the bottom in the form of flakes. This cleaning method is quite simple, but takes time.

To precipitate the maximum amount of salts, the water must be boiled for at least 30 minutes, and then cooled and settled. Afterwards, the water is carefully drained so as not to affect the sediment.

Freezing

The freezing method is based on the fact that pure water freezes faster, and those containing salts freeze more slowly.

To purify water in this way, you need to place a container of water in the freezer and after 2/3 of the water freezes, drain the rest.

Unfrozen water will be a solution of salts, you need to drain it.

After the remaining water has been removed, the ice is defrosted and melt water after heating (to room temperature) use for watering.

Filtration

The choice of household filters is huge, and the degree of cleaning depends on the characteristics of the cartridge. Even the simplest filter jug ​​significantly softens water and can get rid of not only chlorine, but also other elements (calcium, iron, etc.).

Reverse osmosis filters bring water values ​​closer to distilled water. Filtration helps to obtain water for plants in almost unlimited quantities, however, there is a need to systematically purchase and replace cartridges.

Uses of oxalic acid

Oxalic acid can not only acidify water, but also precipitate some of the dissolved salts. The amount of oxalic acid required to precipitate the maximum amount of salts depends on the characteristics of the water in a particular area and is calculated experimentally.

To do this, add a small amount of oxalic acid to a container of water, which reacts with dissolved salts, which leads to cloudiness of the water.

After the water becomes clear again, you need to add a small amount of acid again and wait for sediment to form.

The procedure is repeated until the water remains clear when adding acid.. Afterwards, you should calculate how much oxalic acid needs to be added to 1 liter of water in order to completely precipitate the dissolved salts.

Infusion with peat

Acidic peat also softens water well and corrects acidity. Peat must be placed in a container with water and left for 1-2 days, and if possible, left for 1 week. In most cases, it is enough to add 100 ml of peat for every liter of water.

Such water not only acquires the required acidity, but is also enriched with additional nutrients. Unfortunately, this method requires a large container and a lot of time for the water to settle.

The choice of water for irrigation depending on the plants

Most indoor plants respond well to watering with soft water of a neutral or slightly acidic reaction, but some plants have special requirements for the composition and acidity of the water.

Heathers, rhododendrons, azaleas, fuchsias, monsteras, ferns prefer a medium acidic substrate. Pelargoniums, begonias, abutilon, tradescantia, and gerberas grow well in slightly acidic soil. To ensure that the acidity of the soil does not change and remains optimal for plants, water for irrigation must be acidified.

Suitable for most plants neutral soil, so it’s easy enough to clean the water for irrigation from hardness salts.

Much less often on windowsills you can find plants that prefer slightly alkaline soils, for example, some types of lady's slipper. They can be watered alkaline water With high content calcium, because they are calciphilous and naturally grow on chalk rocks.

Most plants can tolerate a certain concentration of salts, but epiphytes (bromeliads, orchids) require the most purified water, close to distilled.

When watering plants, regardless of their species, you should always give preference to soft water.

You can always find a way to help purify and soften tap water, because the life expectancy and decorative value of any indoor plant depends on it.

What types of irrigation are there?

Experts distinguish several types of irrigation depending on the purpose of its use:

  • landing And post-landing, which improves the survival rate of crops after sowing seeds and planting seedlings;
  • basic– to replenish moisture in the soil during the growing season;
  • feeding allowing the application of dissolved fertilizers;
  • refreshing– used when high temperature air;
  • anti-frost– to reduce the risk of plants freezing.

It is advisable to use different types watering in the complex. Then the plants will receive everything they need for full development.

When to water the garden?

“How many times a week should I water?” and “How often should I water?” - rhetorical questions. It all depends on your specific site, the characteristics of the soil on it, climatic conditions area and even what vegetables you prefer in the garden.

Below we will analyze the rules for watering certain crops, and now we will try to formulate general rules:

  • it is optimal if watering is regular and timely;
  • Since plants need oxygen, loosen the soil before watering and prevent the formation of a soil crust.

What time of day to water?

Water the garden in the absence of bright sun - in the morning or evening, when moisture evaporation is minimal and water droplets do not turn into sun rays into tiny, scalding lenses (especially during periods of very hot weather).

Morning watering is preferable in cool weather, evening watering in warm weather.

IN evening time Watering should not be delayed, since if the soil does not dry out before cool twilight, this can provoke a surge in fungal diseases;

How often to water?

It is better to water less often, but more abundantly, than often, but in small portions, when the water does not have time to reach the roots;

Do I need to water the plants after transplanting?

Water – seedlings and young plants recently planted in the ground especially need life-giving moisture;

Should I water my garden after rain?

It depends on its duration and abundance - long and calm rain will help the plants much better than heavy but short rain. Stick a dry stick into the ground after precipitation, check to what depth the soil is wet - the bulk of the roots of most vegetable plants are located at a depth of 15 to 30 cm from the soil surface.

How many times a day should I water the beds?

It all depends on the weather, age and well-being of your plants - seedlings planted in the ground are watered daily, after rooting, reduce the frequency of watering to once every 2-3 days; plants in pots or in greenhouses dry faster than ground plants - they are recommended to be watered twice a day. In hot weather, of course, you will have to water more often and more than in cool weather, and areas with light sandy soils dry out much faster than clay soils.

All of the above does not apply to force majeure situations when you did not look into country cottage area for some time, and upon arrival they discovered that the plants frankly required immediate watering. Signs of this may be: noticeably lost turgor, drooping and lethargic (even worse, changed color) stems, leaves and buds, dried and fallen off parts of the plant.

In this case, it is vitally important to save the root system from completely drying out, so the time of day does not matter - carefully loosen the crust of dried soil at the base of the plant and water under the root, several times in small portions, so that the water saturates the soil and passes to the roots without rolling off to the sides .

Is it possible to combine watering with fertilizing?

Even necessary! You can do this with every watering, following the example of European farmers, or according to the scheme of the Doctor of Agricultural Sciences Mecheslava Stepuro. For every 10 liters of water add:

  • for the first watering: 20-30 g of potassium or calcium nitrate;
  • in the fourth watering: 30-35 g of potassium monophosphate;
  • in the seventh watering: 20-25 g of magnesium sulfate (magnesium sulfate);
  • in the tenth watering: 0.5-1 g of water-soluble iron sulfate, manganese, zinc, copper and boric acid;
  • in the thirteenth watering: 30 g of potassium monophosphate.

What water to water the garden

Temperature and quality of irrigation water – important factor for plants.

Why can't you water with cold water? To prevent plants from getting sick after experiencing temperature stress (the same goes for too hot water). In addition, too cold or too warm water has a bad effect on the absorption capacity of the root system and the vital activity of soil microorganisms.

That's why optimal temperature water for irrigation will be neutral in the range of 15-25°C. This can be achieved by filling a large container with water from a water supply or an artesian well in the evening, letting it settle overnight (or, depending on the outside temperature, warm up during the day) and reach a temperature that is comfortable for the plant.

The optimal difference between water and air temperatures is 15-20°C. If it is exceeded, the fruits may crack and lose their presentation.

Even if it’s hot outside and you think the plants will like it cold water from a hose, it's better to take your time and let it warm up. Only cabbage, garlic and onions, which are cold-resistant crops, can be watered with cold water. But even in this case, we recommend not pouring water under the root, but spraying it using a diffuser.

Sedimentation of water (especially tap water, river water) will also help to precipitate or evaporate possible harmful impurities, like chlorine in the first case or an abundance of suspended particles in the second. Regular water for watering, you can alternate with healing infusions twice. For example, 3 tbsp. ash per 3 liters of water or the peel of two large onions, infused for a couple of days in 3 liters of water.

You can also use rainwater for irrigation, but only if there are no industrial facilities. Otherwise the water will be contaminated.

Watering vegetables in open ground

Let's look at the watering requirements for some of the most common vegetable crops.

There are 4 groups of vegetables based on their ability to absorb water. For ease of remembering, we have placed them in a table.

Group Water requirement Name of crops
1 They use up water quickly; fractional but frequent watering is required. Cabbage, cauliflower, Chinese cabbage, kohlrabi, lettuce, radish, cucumber, spinach, celery
2 They have a developed root system and are able to extract water at a depth of up to 80 cm. Moisture consumption is economical, so frequent watering is not required. Tomatoes, carrots, melons
3 They use water sparingly, although it is not easy for them to extract it from the soil. They need watering only during the first half of growth. Onions, spring onions, garlic and other onion crops
4 Absorbs water well and uses it intensively. Responds gratefully to irrigation. Beet

Watering also depends on the period of plant growth and soil composition. For young tomato and pepper plants, 0.5 liters per bush is enough. During the flowering period, the norm increases to 0.7 liters. And adult plants need at least 1 liter of water. Cucumbers are more moisture-loving, and they require 0.7 liters even before flowering begins. During fruit formation - 1 liter, and after - at least 1.5 liters per plant.

As for the soil, keep in mind that sandy and light loamy soil dries out much faster than clayey and loamy soil. This means that the plants in it need to be watered more often.

Squeeze a handful of soil in your hand; if a lump has not formed, the soil is too dry.

How to water tomatoes in open ground

1-2 times a week, preferably in the morning, under the root with settled or collected rainwater at the rate of about 30 liters per 1 sq.m. Tomatoes without watering begin to signal their poor condition: the leaves become smaller and turn yellow, curl, the ovaries fall off, the resulting fruits slow down their growth and ripening, and in critical cases, blossom end rot appears on them.

How to water ground cucumbers

After the flowers appear, be sure to use warm water every 3-4 days at the rate of about 30 liters per 1 sq.m. You should not water under the root - if the root collar is constantly flooded, the root may rot. In addition, in good weather, cucumbers tolerate any other method of watering (sprinkling, over leaves).

How often to water peppers and eggplants in open ground

For uniform growth and full flowering, they require constant soil moisture, but do not tolerate sprinkling. Water them at the root 1-2 times a week with warm, settled water at the rate of about 15-25 liters per 1 sq.m, soaking the soil under the bushes to a depth of at least 25-30 cm. At temperatures below 15°C, watering should be stopped altogether; in order to avoid damage to plants by gray rot.

How often to water cabbage in the garden

Watering cabbage in open ground should be abundant and frequent - every 2-3 days at a rate of at least 30 liters per 1 sq.m., soaking the soil to a depth of at least 40 cm. In this case, the water can be quite cool. In hot weather, sprinkling can be used, cloudy weather water at the root. When there is a lack of moisture, cabbage is actively attacked by pests - cabbage fly and cruciferous flea beetle.

How often to water carrots in open ground

1-2 times a week with cool water at the rate of about 30 liters per 1 sq.m., or sprinkling. The root crop is most demanding of moisture in the first half of the growing season (signaling a lack of liquid by darkened, curled leaves), then the norm can be reduced, and three weeks before harvesting, watering can be stopped altogether.

Is it possible to water beets with cool water?

Yes, she is also not capricious in terms of temperature regime watering - the main thing is that the soil is moistened at least 30 cm deep. Moreover, over the entire season, in normal, non-drying weather, it is enough to water the beets only 4-5 times, by sprinkling or at the root in the morning at the rate of about 30 liters per 1 sq.m. The plant will “inform” about a lack of moisture by the darkened (purple-brown) color of the tops and the release of flower stalks instead of the formation of root crops.

How to properly water onions and garlic in the garden

These crops should not be watered too much - they are very “thirsty” only during the period of bulb formation, when they will have to allocate at least 35 liters per 1 sq.m. Before this, watering once a week is enough, moistening the soil only 10-15 cm deep (look at the tips of the feather to see if they have begun to turn yellow). About a month before harvesting, watering should be stopped altogether: excess moisture will cause the bulbs to ripen worse and will be poorly stored in winter.

Do not forget that attitudes towards watering can be different even within the same culture. different varieties. Mainly varieties early dates ripening is more demanding on the amount of moisture, later ripening is less demanding.

If 10-12 cm of soil is saturated with moisture, it means you did everything right and the plants will not suffer from thirst.

Watering vegetables in a greenhouse

Watering in a greenhouse has its own nuances. Yes, it should also be carried out during a period when the sun is not too active, yes, the frequency of watering also depends on the type of soil and the type of plant. However, we have already mentioned that greenhouse plants require more water than in open ground, since due to the increased temperature the stems and leaves wither faster. Because of this same internal “climate,” more heated water can be used in the greenhouse for irrigation than outside on the site.

In addition, if there is excessive or improper watering, excess condensation may form inside the greenhouse - do not forget to ventilate the greenhouse after watering. Spot watering (bottle irrigation) will also help reduce the volume of condensate.

Watering cucumbers and tomatoes in a greenhouse, in principle, is not particularly different from that in open ground - keep an eye on the soil moisture and appearance plants.

The higher the temperature inside the greenhouse, the higher the air humidity around the tomatoes and cucumbers should be. To achieve this, you can place open containers of water near the beds, and also spray the plants and walls of the greenhouse with water. Don’t overdo it - by evening, make sure that there are no drops of water left on the bushes. On standard greenhouse 2x3 m in size one 20-30 liter barrel is enough. As it evaporates, simply add water to the container.

Water cucumbers before flowering once every 5-7 days, and after - once every 2-3 days at the rate of about 10-20 liters per 1 sq.m. We remind you that cucumbers like to be watered at the root, and the water must be warm enough, otherwise it can provoke the appearance of fungal diseases.

Tomatoes in a greenhouse should not be watered in the first week after planting seedlings. Then water them every 3-7 days (more often in hot weather). Before flowering, this is done at the rate of 4-5 liters of water per bush, and after planting flower clusters - 1-2 liters. Increase the watering rate again to 3-5 liters already during fruit set.

Tomatoes should not be watered on the leaves, otherwise the plants will be poorly pollinated, the fruits will fall off, and there will be a high probability of infection with brown spot.

It is most convenient to water plants in a greenhouse or hotbed using a watering can with a nozzle - this way the plants below and above on the racks will receive required quantity moisture. If the territory is large, we already need automatic systems glaze. Of these, the drip type is considered the most economical for greenhouses, and the rain type is the most technologically complex. We will tell you what this is below.

If the greenhouse is too hot, hose down the paths with cold water. This will help lower the air temperature a little.

Automatic plant watering systems

An automated garden watering system will allow you not to waste extra time on this procedure, and also distribute moisture evenly throughout the garden. large area and save it. These systems come in the form of drip, jet and sprinkler systems - each has its own advantages and disadvantages.

So, sprinkling is not suitable for all crops - for example, cabbage, eggplants and tomatoes do not like it when it “rains on their heads”. In addition, irrigation is dangerous on a hot sunny day, because... unable to quickly dissolve dried soil crust (especially on heavy clay soils) and only creates a lot of scorching lens droplets on the leaves. But lawn grass and young shoots will be grateful to you for this method of watering outside the active sun - large strong jets will not wash away their delicate roots. Automatic watering is also ideal for slopes and areas with complex microrelief.

An automatic sprinkler consists of a system of pipes dug into the ground and connected by ball valves. Sprinklers are attached to their ends facing the surface. different types(they are chosen depending on the shape, size and topography of the site). The design is equipped with an electronic control that allows watering without your participation. You can set the start and end time of watering, jet pressure and other parameters.

Drip and jet irrigation systems can be either semi-automatic (they will have to be turned on and off manually) or automatic (the computer will do all the work). These are long hoses or tubes with holes pointing down and valves closed. Water comes here from a large storage tank and, opening the valves with its pressure, flows evenly and accurately to the roots of the plants, without being spent on evaporation and watering the surrounding weeds. The advantage of such a system is the possibility of its use in areas with uneven terrain and for the vast majority of crops. Possible problems– system clogging.

Choose a watering method that is suitable for your site and your plants, do not forget to “water” your garden on time and sufficiently - and a rich harvest will not keep you waiting.

Why is such watering dangerous?

By watering with unprepared cold water, you can provoke a kind of shock in some plants. It also affects the normal functioning of beneficial microorganisms and worms located near the soil surface. They stop processing plant residues to the same extent, providing the plants with the necessary nutrients. The greater the temperature difference between water and environment, the more pronounced this imbalance will be. Regular lack of nutrients will affect the health of plants, their immunity will weaken, and pests and diseases will appear accordingly.

Crops that should not be watered with cold water

Zucchini, tomatoes, peppers, tomatoes, roses, squash, cucumbers and some other crops are especially susceptible to watering with cold water. Water for watering them must be left to stand in a barrel for a day so that it warms up to normal temperature. Otherwise, at best, they will slow down in growth, and at worst, they may begin to gradually die.

Among those particularly susceptible to cold watering are onions. With regular hypothermia, his feathers will begin to turn yellow, and he will get sick more often.

Another negative point when watering with cold water from a hose is that water gets on the leaves of plants, while many of them need to be watered strictly at the root (for example, tomatoes).

Whatever water you use for irrigation, evening watering will help eliminate large temperature differences. Under no circumstances should you water the plants in the heat of the moment, as this can cause numerous burns on the leaves.

What harm is caused to indoor plants when watering with cold water?

Water for plants is an important component that helps carry out all necessary physiological processes:

  • dissolves organic and chemical compounds;
  • promotes the absorption of soil solutions by plants;
  • evaporating from the surface of the leaves helps the flowers maintain the required temperature.

Understanding these transformations explains why it is not recommended to water plants with cold water: the processes of dissolution and absorption slow down or become impossible.

Experiments conducted by scientists have proven that a number of plants, when watered with warm water, develop normally and bloom faster:

  • pelargoniums;
  • gloxinia;
  • amaryllis;
  • hydrangeas;
  • hippeastrum, others.

If you water flowers with cold water, they weaken and begin to shed ovaries and buds.

If not properly cared for, seemingly healthy plants begin to wither, the foliage turns yellow and falls off, the root system experiences shock and gradually rots. As a result, the flower may die.

In other plants, the foliage reacts sharply to improper watering: white or colorless spots and yellowing form on it. If the cause is not eliminated in a timely manner, the indoor flower may lose its leaves altogether.

It is not recommended to water indoor plants with cold water because the beneficial substances in the soil do not dissolve well in it. This prevents plants from receiving the nutrition they need. It turns out that there are enough useful elements in the soil, but they are inaccessible to the root system, and the plant starves.

What is the best water to water indoor plants?

The best option is settled water at room temperature. It is necessary to settle the water for 2-3 days so that the chlorine contained in it evaporates and the calcium and magnesium salts precipitate. An excess of these chemical elements adversely affects the growth and development of the plant, as it disrupts the absorption of iron, manganese, phosphorus, aluminum and other components by the root system.

Rainwater is the softest and can be collected in a container, brought to room temperature and used. It is important to ensure that water does not stagnate in containers for a long time. It is also recommended to mix clean rainwater halfway with settled tap water to eliminate excessive softness of the irrigation liquid.

Some gardeners adapt to freezing water in plastic bottles for 10-12 hours, then the separated non-freezing brine with impurities is drained, and the clean ice is thawed at room temperature. Melt or rain water contains fewer impurities than regular settled water, but provided that the grower lives in an ecologically clean area and the precipitation does not contain harmful chemical compounds.

It is clear why you should not water plants with cold water: it is very harmful for them. But warm water cannot be used either; a temperature only 2-3 0 C above room temperature is allowed. Warm water (above 40 0 ​​C) is used if necessary to stimulate plant growth.

Damage from watering with cold water

Many of the plants that grow in our homes originated in tropical countries. They were watered with rainwater. In order not to disturb the vital activity of plants, it is necessary to follow proper care after them. Watering with cold water causes weakness in plants, which in turn leads to the falling of flowers and buds. Due to non-compliance with the watering temperature, the flower turns yellow, after which the leaves begin to fall off. The worst option is rotting of the root system, which leads to the death of the plant.

Another nuance is the poor dissolution of nutrients in the soil when watering with cold water. As a result, the indoor plant is not able to obtain the beneficial substances that are in the soil. But you shouldn’t abuse the water temperature. For example, for some plants, water at a temperature of about 45ºC can become critical.

Optimal water for irrigation

The best choice is water at room temperature that has been standing for some time. There is chlorine in the water, which, when it sits for three days, evaporates to a greater extent, and magnesium and calcium salts precipitate. If the water is not settled, a large amount of these elements will accumulate in the soil, which will interfere with the proper absorption of beneficial minerals.

Rainwater, which is sufficiently soft, is considered the most useful. Once brought to room temperature, it can be used for watering.

When there is a water supply at the dacha (a well has been drilled) and a long irrigation hose is connected, with which it is physically convenient to water the beds and bushes, a reasonable question arises: is it possible to water with cold water?

Houseplants, like humans, cannot do without water. This is due to the fact that the water in required quantity promotes the dissolution of nutrients found in the soil. That is why it is necessary to organize proper care and watering of indoor plants. Few people know that it is strictly forbidden to water plants with cold water. Let's try to understand this statement.
