Why plants are not recommended to be watered with cold water. Watering the garden with cold water Why you can not water with cold water

About watering plants

It is with watering with such a seemingly simple procedure that the most gross mistakes of amateur flower growers 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 should 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 need of each plant for water is your first task.

Since the need for moist nutrition is different, only by observing each individual plant for some time, you can 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. Soil properties change: excess moisture increases its acidity, and lack of it increases its alkalinity.

For example, cacti die not from excessive watering, but from the high acidity of the soil, which is formed from excessive water intake.

If the plant does not have enough moisture, irregular watering, 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 a lack of moisture, the leaves will become lethargic and drooping, and then completely dry out. The flowers fade and fall just as quickly.

With excessive watering, water clogs all the pores in the soil, the root system is flooded. The roots stop breathing and die, and the aerial part of the plant dries up, since nutrients are not supplied to it.

How often should plants be watered?

Florists are armed with several ways to check the pre-irrigation condition of the soil. Dry earth 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 topsoil. Watering is needed if it has dried out by 1 - 1.5 cm.

The speed of drying of the soil depends on the size of the pot and the composition of the earthen mixture. The moisture content in a smaller container is consumed faster than in a larger one. Therefore, plants planted in large containers are watered less often. More frequent watering is required for plants planted in ceramic pots (compared to plastic ones, with equal other care methods).

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

During the period of strong growth, and this is spring and summer, plants, with rare exceptions, are watered daily, and many species even 2 times a day (especially in hot weather). With the weakening of growth, moisture consumption decreases, and the plant needs it least of all in a dormant state.

Seasonal differences in the irrigation regime are due to the different needs of plants for moisture during the period of growth and dormancy. When watering during the spring-summer active growth of plants, gardeners' mistakes, firstly, are rare, and secondly, most of them can be quickly corrected, since all plants need watering.

It should be cautioned: even a small mistake in watering in the autumn-winter season can become difficult to fix, if not completely fatal. So, abundant watering of indoor crops at this time leads to a violation of the breathing of the roots, causing them to rot.

Starting in September, watering is gradually reduced, but with the inclusion of central heating, it is slightly increased. It is very important to follow the rules for watering when the temperature drops during the off-season (second half of October), since the metabolism of plants at this time is sharply reduced. And with slow life processes, the plant cannot receive and give 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 strengthened with the appearance of the first leaf after winter. And be sure to reduce watering during a cold snap in April - May, when the heating is turned off.

In the warm season, the vast majority of crops are abundantly watered. However, it is necessary to water not just all crops, but personally each of them, for this it is necessary to observe and know the characteristics of each. So, if the earthy ball of a palm tree and many other tubs begins to dry out, then the tips of their leaves become brown and dry.

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

Watering ampelous plants

Watering ampelous 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, standing on the windowsill, as 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. Once a week, you can remove the hanging pots and immerse them in water so that the earth is saturated with moisture “with a margin”, drain excess moisture and return the plants to the height of the position.

In winter, ampelous plants need to be sprayed often, since the air at the top is not only warmer, but also drier. The most convenient way to humidify the air around plants is to use a spray.

What water to water the plants?

All flower growers agree that the best water is rainwater, but indoor crops are watered with ordinary tap water. Snow water or ice water obtained from refrigerators is also used.

Tap water must be defended for at least a day in an open container and during this time it should be poured 2-3 times in a thin stream so that it is saturated with atmospheric oxygen and chlorine evaporates from it.

As for boiled water, even experts have disagreements about this. Some advocate it (soft), others are categorically against it (in the process of boiling, the air necessary for plants is removed from it), others strongly advise watering with water drawn from a hot water tap (it is close to boiled in hardness). 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. Optimum 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 flower growers add a few drops of phosphoric, sulfuric, hydrochloric or other acid to a bucket of water. However, constant watering with such water leads to acidification of the substrate. Do not soften water by adding sodium, which is toxic to plants.

Plants absolutely cannot stand 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 higher than the temperature of room air, during the dormant period - only room temperature, since watering warm can lead them to premature awakening.

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

The same applies to the water in which the vegetables were boiled. The settled mineral water (without carbon dioxide) can also be used for irrigation. But it is absolutely impossible to water the plants with soapy water.

How to water plants properly?

With traditional watering from above, a jet 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 all the first portion of water is absorbed into the ground, pour until it comes out onto the pan. An hour after watering, the water from the pan should be drained.

Many crops are recommended to be watered from below, i.e. pour water into the pan, from where it is gradually absorbed into the ground. If the whole lump is wet and the surface of the earth in the pot is wet, watering is complete. If all the water is absorbed, and the earth on top remains dry, then the pan must be filled with water again.

Saintpaulia, gloxinia and cyclamen do not like water on the leaves. They should be watered from below, immersing the pots in water approximately to the "shoulders" until the top layer of soil in the pot becomes wet. Next, the pot is placed on a pallet so that the glass has excess moisture, and only after that the plant is returned to its permanent place.

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

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

How to correct the 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 put the pot on the "hangers" in a container of water until the soil on top becomes wet.

More often the opposite happens - plants suffer from excessive watering. At first, the “drenched” plant does not show signs of its disease state, but over time, its leaves become lethargic, and if you continue to water, they will fall off and the plant will die.

In case of waterlogging, the plant is taken out of the pot, the rotten roots are cut with a knife. The places of the cut should be sprinkled with crushed coal, let it dry, then transplant the plant into the soil mixture of the previous composition, but with the addition (up to half) of coarse-grained sand.

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

Use a suitable method to gradually moisten the soil in pots. If there are not many plants, move the flower pots to a more shaded and cool place in a wide container of water. Good results for moderately watered plants are obtained by covering the soil with well-moistened moss.

For compact plants, you can arrange the so-called "dropper". To do this, a wet sponge or a plastic bag of water with a tightly tied neck is left 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 of water, closing it with a cork 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 accumulator - hydrogel - is widely used. This is a kind of miniature sponge, which looks like translucent granules: they absorb only 2 g and tenaciously hold up to 1 liter. water. When swelling in water, a miracle - the granules increase hundreds of times, become jelly-like, while maintaining their strength.

With a single watering, an earthen lump with a hydrogel filling absorbs a really huge amount of water, which it gives to the roots of plants gradually, as if automatically maintaining optimal soil moisture.

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

no other way.

The granules are introduced into the soil in a simple way: several holes are pierced with a pencil in an earthen coma along the edge of the pot and the granules are poured into them. It is more convenient to mix them with the soil for transplanting plants at the rate of 2 g of granules per 1 kg of soil.

Hydrogel with a full complex of fertilizers is especially effective. The roots of plants, penetrating inside the jelly-like granules, are supplied with water and all nutrients for a long time.

A one-time application of hydrogel is 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 stock.

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, as the useless evaporation of moisture decreases.

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

If you read various sources, you can find a bunch of requirements for water - it must be warm, from a stagnant reservoir (not from a river) or settled, and you can also find tips to mix it before watering to saturate it with oxygen.
Cold water in heat-loving crops slows down the development of the root system.
The most thermophilic are cucumbers, zucchini, pumpkins, squash, melons. They are recommended to warm the water up to 20 degrees.
Moderately heat-loving - beets during the germination period, tomatoes, peppers and eggplants.
I them desirable 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 a garden with ice-cold well water, and claims that everything is growing well with him.
I also do not always have the opportunity to heat and defend water, so I periodically pour cold (not ice) water, and I have river water (there is simply no other).
First of all, I save warm for cucumbers and other pumpkin crops.
In the second - for those crops that grow in a greenhouse. The rest I water with a hose.
I also try to water only the planted seedlings with warm water, so that it takes root easier (if I plant it in warm weather).
Maybe I will express a seditious thought, but from my own experience I have come to the conclusion that the time of watering is more important than the temperature of the water.
Definitely do not need to water in the middle of the day in the midst of the heat.
It is necessary to water so that there is no excess dampness on the leaves of plants at night - here it can really provoke the development of diseases.
Therefore, it is better to water the greenhouse and the greenhouse in the morning, so that excess moisture from the air is gone during the day, and open ground in the evening, but so that the top of the earth and the leaves have time to dry before sunset, and inside the earth remains moist. Here we must remember that warm water will evaporate faster and easier, but it is better to pour 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 pour cold water than not water at all.

Properties and composition of water

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

Water with a high concentration of salts is considered hard and needs to be treated., with a low salt concentration - mild and can be used without prior preparation.

Pure water (distilled) can only be obtained by distillation, but for most flower growers this purification method is not available and is not needed.

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

Acidity of water and methods of its correction

Tap water is most often alkaline, 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 a normal or slightly acidic reaction.

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

Lemon acid;
Askorbinka;
Oxalic acid;
Vinegar (possible, but undesirable).

Irrigation water without purification

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

In addition, in urban areas, precipitation is often too polluted with exhaust gases and other harmful substances. River and spring water can 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 matter useful for plant growth and development.

Irrigation water temperature

For watering plants, it is customary to use water at room temperature. However, it is better to water with water, the temperature of which is several degrees warmer than the air temperature.

Under no circumstances should plants be watered with cold water., since a sharp cooling of the root system can lead to falling leaves and rotting of the roots.

Water purification

Tap water contains many impurities, and using it to water plants can be detrimental. 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 what the plant needs. Excess chlorine leads to yellowing of the leaves, reduced plant growth and poor rooting.

The easiest way to remove chlorine is to settling water in an open container.. In this case, most of the chlorine evaporates during the day. You can also use special filters designed to remove chlorine from water.

Ways to purify 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 to purify 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 method of cleaning is quite simple, but takes time.

To precipitate the maximum amount of salts, water must be boiled for at least 30 minutes, and then cooled and settled. After 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 containing salts slower.

To purify water in this way, it is necessary 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 rest of the water is removed, the ice is thawed and the melt water after heating (to room temperature) is used for irrigation.

Filtration

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

Reverse osmosis filters bring water performance closer to distilled water. Filtration helps to obtain water for plants in an almost unlimited amount, however, there is a need for a systematic purchase and replacement of cartridges.

Uses of oxalic acid

Oxalic acid is able not only to acidify water, but also to precipitate part 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 given area and is calculated empirically.

To do this, a small amount of oxalic acid is added to a container of water, which reacts with dissolved salts, which leads to cloudy water.

After the water becomes clear again, it is necessary to add a small amount of acid again and wait for a precipitate to form.

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

Infusion with peat

Acid peat also softens water well and corrects acidity. Peat must be placed in a container with water and insisted for 1-2 days, and if possible, then 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 desired acidity, but is also enriched with additional nutrients. Unfortunately, this method requires a large capacity and a lot of time to settle the water.

The choice of water for irrigation depending on the plants

Most houseplants respond well to neutral or slightly acid soft water, but some plants have special requirements for the composition and acidity of the water.

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

Neutral soil is suitable for most plants, so it is enough to simply clean the water for irrigation from hardness salts.

Much less often on the windowsills you can find plants that prefer slightly alkaline soils, for example, some types of venus slipper. They can be watered with alkaline water with a high calcium content, as they are calciphiles and grow naturally 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 clean and soften tap water, because the life expectancy and decorative effect of any indoor plant depend on it.

What types of irrigation are there?

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

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;
top dressing, allowing you to make dissolved fertilizers;
refreshing– used at high air temperature;
anti-frost- to reduce the risk of freezing plants.

It is advisable to use different types of irrigation in the complex. Then the plants will receive everything necessary for the full development.

When to water the garden?

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

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, do not allow 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 in the evening, when moisture evaporation is minimal, and water droplets do not turn into tiny scalding lenses under the sun's rays (especially for periods of very hot weather).

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

In the evening, watering should not be delayed, because if the earth 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 get to the roots;

Do plants need to be watered after transplanting?

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

Should I water my garden after it rains?

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

How many times a day to 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 shown watering 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 much faster than clay ones.

All of the above does not apply to force majeure situations when you did not look at the summer cottage for some time, and upon arrival found that the plants frankly require immediate watering. Signs of this can be: noticeably lost turgor, drooping and lethargic (even worse - changing color) stems, leaves and buds, dried and fallen off parts of the plant.

In this case, it is vital to save the root system from complete drying out, so the time of day does not matter - gently loosen the crust of the dried earth at the base of the plant and water it under the root, several times in small portions, so that the water soaks the soil and goes to the roots without rolling to the sides. .

Is it possible to combine watering with top dressing?

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 Mecheslav Stepuro. For every 10 liters of water add:

in 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

The temperature and quality of irrigation water is an important factor for plants.

Why can't you use cold water? So that the plants do not get sick when they experience 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.

Therefore, the optimal water temperature 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 artesian well in the evening, letting it settle overnight (or, depending on the temperature outside, warm up in a day) and reach a temperature comfortable for the plant.

The optimum difference between water and air temperature 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 the cold water from the hose, it's best to take your time and let it warm up. You can only water with cold water cabbage, garlic and onions, which are cold-resistant crops. But even in this case, we recommend that you do not pour water under the root, but spray it with a diffuser.

Settling water (especially tap water, river water) will also help to precipitate or evaporate possible harmful impurities, such as chlorine, in the first case, or an abundance of suspended particles, in the second. Ordinary water for irrigation can be alternated twice with healing infusions. For example, 3 tbsp. ash per 3 liters of water or the husks 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 near your site. Otherwise, the water will be polluted.

Watering vegetables in the open field

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

In total, there are 4 groups of vegetables according to their ability to absorb water. For ease of remembering, we put them in a table.

Group	Water requirement	Name of crops
1	Consume water quickly fractional, but frequent watering is required.	Cabbage, cauliflower, Beijing, 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. The moisture consumption is economical, so frequent watering is not required.	Tomatoes, carrots, gourds
3	They use water economically, although it is not easy for them to extract it from the soil. Need watering only during the first half of growth.	Bulb onion, onion, garlic and other onion crops
4	It absorbs water well and consumes it intensively. Responds gratefully to irrigation.	Beet

Watering also depends on the period of plant growth and soil composition. Young plants of tomatoes and peppers need 0.5 liters per bush. During the flowering period, the rate increases to 0.7 liters. And adult plants need at least 1 liter of water. Cucumbers are more moisture-loving, and 0.7 liters are required for them even before flowering begins. During the formation of fruits - 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 clay 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 outdoors

1-2 times a week, preferably in the morning, at the root of 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 formed fruits slow down their growth and ripening, and in critical cases, top rot appears on them.

How to water ground cucumbers

After the appearance of flowers - every 3-4 days, always with warm water at the rate of about 30 liters per 1 sq.m. Watering under the root is not worth it - with constant flooding of the root neck, the root can rot. In addition, in good weather, cucumbers perfectly tolerate any other method of watering (sprinkling, on the leaves).

How often to water peppers and eggplants outdoors

For uniform growth and full flowering, they require constant soil moisture, while they do not tolerate sprinkling. Water them under the root 1-2 times a week with warm settled water at the rate of about 15-25 liters per 1 sq.m, wetting the soil under the bushes to a depth of at least 25-30 cm. At temperatures below 15 ° C, watering should generally be suspended, 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 plentiful and frequent - every 2-3 days at the rate of at least 30 liters per 1 sq.m, wetting the soil to a depth of at least 40 cm. At the same time, the water can be quite cool. In the heat, you can apply sprinkling, in cloudy weather, water under the root. With a lack of moisture, cabbage is actively attacked by pests - cabbage fly and cruciferous flea.

How often to water carrots in the open field

1-2 times a week with cool water at the rate of about 30 liters per 1 sq.m, it can be sprinkled. The root crop is most demanding on moisture in the first half of the growing season (indicating a lack of fluid with darkened twisted leaves), then the rate can be reduced, and watering can be stopped altogether three weeks before harvesting.

Is it possible to water beets with cool water?

Yes, it is also not capricious in terms of the temperature regime of irrigation - the main thing is that the earth be moistened at least 30 cm deep. Moreover, for the whole season, in normal non-drying weather, it is enough to water the beets only 4-5 times, by sprinkling or under the root in the morning at the rate of about 30 liters per 1 sq.m. The plant will “report” a lack of moisture with a darkened (violet-brown) color of the tops and the release of peduncles instead of the formation of root crops.

How to properly water onions and garlic in the garden

These crops should not be watered too plentifully - they “thrive” strongly only during the formation of the bulbs, when they have to allocate at least 35 liters per 1 sq.m. Before this, one watering per week is enough, moistening the earth only 10-15 cm deep (focus on the tips of the pen - if they have begun to turn yellow). About a month before harvesting, watering should be stopped altogether: the bulbs will ripen worse from excess moisture, and in winter they will be poorly stored.

Do not forget that the attitude to watering can be different even within the same crop for different varieties. In general, varieties of early ripening are more demanding on the abundance of moisture, late - less.

If 10-12 cm of soil is soaked with moisture, then 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 outdoor plants, because due to the increased temperature, the stems and leaves wither faster. Because of this same internal “climate”, warmer water can be used for irrigation in the greenhouse than outside on the site.

In addition, with abundant or improper watering, excess condensate may form inside the greenhouse - do not forget to ventilate the greenhouse after watering. Spot irrigation (bottle irrigation) will also help reduce the amount of condensate.

Watering cucumbers and tomatoes in a greenhouse, in principle, is not particularly different from that in open ground - keep an eye on soil moisture and the appearance of 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, as well as spray the plants and walls of the greenhouse with water. Do not overdo it - by the evening make sure that there are no drops of water left on the bushes. One 20-30-liter barrel is enough for a standard greenhouse measuring 2 × 3 m. As it evaporates, simply add water to the container.

Water cucumbers before flowering 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 love watering under the root, besides, the water must be warm enough, otherwise you can provoke the appearance of fungal diseases.

Tomatoes in the greenhouse in the first week after planting seedlings should not be watered. 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 laying flower brushes - 1-2 liters. Again increase the watering rate to 3-5 liters already at the time of fruit set.

Tomatoes should not be watered over the leaves, otherwise the plants will pollinate poorly, 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 greenhouse from a watering can with a nozzle - this way the plants below and above on the racks will receive the right amount of moisture. If the area is large, automatic irrigation systems are needed. Of these, for greenhouses, the drip type is recognized as the most economical, and the rain type is the most technologically complex. We will talk about what it is below.

If the greenhouse is too hot, spray the paths with cold water from a hose. This will help bring the temperature down a bit.

Automatic watering systems for plants

An automated garden irrigation system will allow you not to waste extra time on this procedure, as well as evenly distribute moisture over a large area and save it. These systems are drip, jet and sprinkling (sprinkling) - each has its own advantages and disadvantages.

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

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

Drip and jet irrigation systems are either semi-automatic (they will have to be turned on and off manually) and automatic (all the work will be done by a computer). These are long hoses or tubes with holes pointing down and closed valves. Water comes here from a large accumulator and, opening the valves with its pressure, gets evenly and accurately to the roots of 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 - clogging of the system.

Choose the method of watering that suits 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 surface of the soil. They cease to process plant residues in the same volume, providing plants with the necessary nutrients. The greater the temperature difference between water and the environment, the more pronounced this imbalance will be. Regular lack of nutrients will affect the health of plants, their immunity will weaken, respectively, pests and diseases will appear.

Crops that should not be watered with cold water

Particularly susceptible to irrigation with cold water are zucchini, tomatoes, peppers, tomatoes, roses, squash, cucumbers and some other crops. Water for their irrigation must be defended during the day in a barrel 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, 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 under the root (for example, tomatoes).

Whatever water you use for irrigation, evening watering will help to eliminate a large temperature difference. In no case do not water the plants in the heat itself, by doing this you can provoke numerous burns on the leaves.

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

Water for plants is an important component that helps to carry out all the 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 plants are not recommended to be watered with cold water: the processes of dissolution and assimilation slow down or become impossible.

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

pelargoniums;
gloxinia;
amaryllis;
hydrangeas;
hippeastrums, others.

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

With improper care, seemingly healthy plants begin to wither, the foliage turns yellow and crumbles, the root system experiences shock and gradually rots. As a result, the flower may die.

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

Indoor plants are not recommended to be watered with cold water, also because useful substances in the soil are poorly dissolved in it. This prevents the plants from getting the nutrition they need. It turns out that there are enough useful elements in the soil, but they are not available for the root system, the plant is starving.

What is the best water to water indoor plants?

The best option is settled water at room temperature. It is necessary to defend the water for 2-3 days so that the chlorine contained in it evaporates, and 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.

The softest is 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 in order to eliminate excessive softness of the irrigation liquid.

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

It is clear why it is impossible to water the plants with cold water: it is very harmful for them. But warm water cannot be used either, the temperature is only 2-3 0 C higher than room temperature. Warm water (above 40 0 C) is used as needed to stimulate plant growth.

Harm from watering with cold water

Many of the plants that grow in our home originated in tropical countries. They were watered with rainwater. In order not to disrupt the vital activity of plants, it is necessary to follow the proper care of them. Watering with cold water causes weakness in plants, which in turn leads to the fall of flowers and buds. Due to non-observance of the watering temperature, the yellowing of the flower occurs, after which the leaves begin to fall off. The worst option is the 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 of this, the indoor plant is not able to get the nutrients that are in the soil. But do not abuse the temperature of the water. For example, for some plants, water temperatures around 45ºC can become critical.

Optimal water for irrigation

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

The most useful is rainwater, which has sufficient softness. When brought to room temperature, it can be used for watering.

When there is water supply at the dacha (a well is 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 irrigate with cold water?

Irrigation is one of the main methods of treatment. Even the most carefully fertilized and nurtured plants will not grow well, watering the plants if you do not provide them with the required dose of water. Lack of water will make the plants less squiggle, increase their susceptibility to disease, and most of all, they will not look beautiful. It is true that our garden's watering needs can be greatly reduced accordingly, so that the garden mimics the natural habitat. However, most ornamental plants available in nurseries are selected varieties, which is why plants that require regular watering are watered, especially during periods of drought, not to mention that the lawn without proper watering quickly loses its decorative effect.

How often should I water garden plants
How to water from a willow.
The frequency of watering depends on many factors, including the time of year, why the plants are watered, weather conditions, and the requirements of particular species (among the types of garden plants, we find the elimination of periodic water shortages quite good). Newly planted plants have a much higher water demand than plants that are already well established can be watered. It also depends on reaching the root system - the greater the larger the surface area from which the plant takes water. So why before transplanting plants, the soil is abundantly watered, perennial plants and annual plants suffer from lack of rainfall faster, whether plants can be watered, and they should be watered more often than plants. In turn, a tree whose root system ascends into the soil absorbs water from the deeper layers grown in this way, the tree usually does not need to be watered like houseplants, except during periods of extreme heat and drought.

why before transplanting plants, the soil is watered abundantly.

Regardless of the age and type of plants, watering should begin even before the leaves lose their turgor (it will no longer be hard, it will dry 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 the soil is abundantly watered before transplanting plants, without waiting for the moment when the consequences of water deficiency will be reflected in the appearance of plants.

Let's remember that plants do not need to be watered daily, on the contrary - too frequent irrigation can cause a lot of harm, which is why plants are not recommended to be watered with cold water, as in case of failure of this treatment. The principle should be better to water less often and more than vice versa. For irrigation to be more efficient, it is necessary to reduce the evaporation of water from the soil surface through mulching, which plants are watered, for example. Bark or gravel. Remember also that bare soil vegetation evaporates faster - so it's a good idea to introduce ground cover plants into your garden.

When to Water Plants

why plants are not recommended to be watered 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 - water droplets left on the leaves concentrate the sun's rays, which plants are watered, which leads to plant burns. In addition, plants heated by strong sunlight watered with cold water experience heat shock, which can adversely affect their status.

How much water supply plants

how to water plants properly

It is worth repeating the principle that it is better to water the plants less often and more. Each watering should be soaked in water, which water to water the plants, the soil layer that has the largest mass of roots - that is, to a depth of about 15-20 cm in case of discount, 30-40 for trees and shrubs, and 15 cm in case lawn… Finer, watering only moisten the top layer of soil in which plants naturally do not grow roots. Usually this mistake is repeated will cause the plants begin to grow roots just below the soil surface, as the plants are properly watered, greatly increasing their vulnerability to drought. Therefore, the correct bottling of products is a time-consuming procedure.
Can plants be watered?
When watering trees and shrubs, remember that the bulk of the active roots go beyond the scope of their crowns, is it possible to water the plants with water, so there is no point in watering the soil next to the chest.

What is the best way to water the garden

Of course, a huge help in garden care is to install an automatic irrigation system. If you additionally install humidity sensors and an automatic programmer, which plants can be watered, this system will not only help us water the garden, but also remember us for this operation.

Those who have opted for the traditional watering method should also benefit from a wide range of equipment that makes this maintenance process easier. First of all, it is worth investing in a good garden hose, it is best to choose kink and twist resistant ones, which can be very inconvenient when we move from a garden hose. In "traveling" with the serpentine, the big advantage is the use of special nights, or garden hose reels (some of which turn on the hose automatically).

how often to water the plants

The need to carry a long hose with you 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 the 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 are moved for a very long time, and therefore heavy, the hose is cumbersome. How often to water the plants.

Take the good end of a garden hose. Plants should be watered carefully, preferably with water spray, a strong stream can damage plant leaves and leach the soil. In the garden, practical tips adjustable water spouts as a powerful stream useful for other garden work, 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 cannot be watered with cold water, you can ditch 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 (irrigated area of irregular, round shape) or swing sprinklers (which are especially good on a square or rectangular surface). It is best to choose models with an adjustable power and flow range, which will allow us to fine-tune surface watering, and why plants cannot be watered with cold water, thus we save water. Many models have a timer, just so it's just the right way to set and turn it on.

why water plants

To qualify for discounts on or near hedges must apply to snakes perforated and penetrating. We can bury it in the ground (at a depth of 15-20 cm), or lay it on its surface and mask, for example. Mulch layer. This solution makes the most efficient use of water, why water the plants, as it is absorbed in close proximity to the plant roots, which greatly reduces evaporation. Another advantage is the fact why water the plants so that the leaves of the plants do not get wet, which can promote the development of fungal diseases.

In order for indoor plants not to get sick, please with beauty and purify the air in the room, they need to be properly cared for: watering, lighting, top dressing. Why houseplants are not recommended to be watered with cold water, what will happen if the grower 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. When caring for indoor flowers, it is important to continue to comply with this condition in order to preserve their vital activity. The same rule is true when growing from seed, and others.
