Why you can not water in the sun and what gardeners say about it

Experts in the field of plant growing and simply experienced gardeners agree that watering plants in the sun at maximum air temperature is a serious mistake. Such actions will do more harm than moisture, and not only shoots, but also the root system will suffer.

Harm for the shoots

After watering, a large number of drops remain on the leaves and stem, which begin to dry quickly under the scorching sun. Firstly, they take part of the energy with the steam - it cools the leaves, but it can also overcool the heat-loving capricious plantings.

Secondly, where the water has dried, a coating of hardness salts is formed, which inevitably exists even in the water that has stood for a day. This, ugly, interferes with breathing and light in the evening and morning, and worst of all - it becomes a cozy home for bacteria and fungi.

Thirdly, the droplets act like a magnifying glass, and the leaves begin to burn in places where there is moisture.

If watering occurs in a closed greenhouse or greenhouse, such consequences are not observed, since the air has high humidity, and the drops evaporate gradually.

Harm to the root system

Actively absorbing moisture, the root system also burns out and dries faster if you water it in the heat. This is especially noticeable on plants whose roots are located close to the soil surface.

Inexperienced gardeners believe that it is during peak heat that plants need extra moisture. But if hydration is carried out in the required volume at a low air temperature, this is enough for nutrition and normal development of the root system and shoots. Water goes deep into the soil, cools and nourishes the plantings.

How watering in the hot sun harms the roots:

  1. "Crust". After watering at high air temperature, a layer forms on the soil surface, which weakly passes oxygen necessary for plant nutrition.
  2. The desire of the roots to grow on the surface of the soil. If watering occurs under the scorching sun, the moisture evaporates quickly, and the roots begin to grow up, trying to "catch" the remaining moisture. As a result, they can be damaged during loosening. Also, they do not seek to get moisture from the soil and depend on frequent watering. If there is not enough moisture in the top layer, the roots begin to dry out.

Tip
It is recommended to loosen the watered earth - this will protect both from the crust and from clumping, oxygen will be easier to pass to the roots. The only thing you need to be careful not to damage the underground part of the plants.

Watering recommendations

To protect plants from drying out, gardeners recommend:

  1. Use a watering can and water the plants under the root. It is important to check if the soil is saturated enough with water.
  2. A good way is drip irrigation. This will not only increase the moisture distribution area, but also reduce the amount of water consumed.
  3. It is not recommended to moisten plants with cold water. To do this, it is prepared in a special container the day before watering, so that it has time to warm up in the sun.
  4. Watering the plants in summer, on a sunny day, can be done until 8-9 a.m. and after 4-6 p.m. (depending on air and soil temperatures).

Drip irrigation

An effective way to prevent the rapid evaporation of moisture from the soil is mulching. The application of this method allows less loosening of the earth, since the top layer is constantly loose. Mulch also reduces weed growth and protects the soil from leaching, erosion, and crusting. Mulch can be organic (hay, straw, bark, sawdust) and inorganic (cut rubber, gravel or sand).

Proper hydration, regardless of other factors, will ensure germination and normal development of plantings. In addition to the time of day, of course, you need to take into account the frequency and volume of irrigation. Be attentive to the recommendations that are given on the package with seeds or attached to the seedlings, so as not to flood or torment you with a thirst for planting, and lush flowering or a rich harvest will not keep you waiting.
