Rules for watering a tomato after planting

When growing tomatoes, it is important to follow the care recommendations, because the yield indicators depend on this. About how to properly irrigate tomatoes after planting, we will describe in the article.

Rules for watering a tomato after planting

Features of watering

If you properly water the tomatoes after planting, this leads to the following results:

  • the risk of diseases in the plant is reduced;
  • bushes begin to develop and form correctly;
  • there is a positive acclimatization to the environment;
  • Maintenance of bushes is simplified.

In order for young seedlings to feel comfortable, it is important to observe the temperature regime. Tomatoes can die from the slightest temperature changes. Soil temperature should not be lower than 12 ° С. But the ambient temperature should be in the range of 18-25 ° C.

Outdoor watering

Planted seedlings should be watered according to certain factors. It is important to pay attention to the weather and soil composition.

Watering should be carried out at a time when the air temperature is not lower than 15 ° C. Soil for tomato should have a neutral reaction of the environment, because and acid and alkaline soil adversely affect it.

Tatyana Orlova (candidate of agricultural sciences):

If it is good to mulch the planting of tomato seedlings with peat, dry humus or just loosening the top layer of soil, then there is no need for watering for the next 6-7 days. You should not often water the planted seedlings of tomato so that the root system does not pamper and begins to grow inland.

Simultaneously with planting seedlings, watering is also carried out.

Tatyana Orlova (candidate of agricultural sciences):

If you have transplanted using the hole method, then it is recommended to pour 2-3 liters of water into each of them. If the method of trenches was used, then the volume of water should be regulated, depending on the number of bushes.

Watering time

After planting, it is better to water the tomatoes in the morning. During this period of time, the sun does not fry so much. If the soil dries strongly from the sun during the day, then you can water it again in the evening.

Tomatoes should be watered with warm water

At least 1 liter of water should be poured under each bush. It is better to use warm water, because cold water can lead to the development of root rot.

Watering in the morning allows the soil to receive the right amount of moisture and remain loose. Young plants need not only moisture, but also oxygen. Dense soil will cause the plant to not be able to get the right amount of air and begin to wither.

Frequency of work

Determine the frequency of irrigation. As soon as the tomatoes take root, loosening the earth around the bush should be carried out. Subsequent irrigation is carried out 1-2 times a week depending on weather conditions. While the seedlings are still small in size, the plants have not closed in a row after each watering, they carry out cultivation.

Loosening should be carried out superficially, not deeper than 3 cm. This method is called dry irrigation. Its implementation is necessary so that evaporation of the soil disappears, and oxygen better gets into the root system.

Tatyana Orlova (candidate of agricultural sciences):

In the soil there are small air channels - capillaries. The drier the soil becomes, the thinner the capillaries. Through these thin capillaries, moisture from the lower layers of the soil rises to the surface and evaporates. Loosening the topsoil destroys these capillaries and moisture ceases to evaporate.

Watering in the greenhouse

Growing tomatoes in a greenhouse implies slightly different rules.

Landing of planting material should be carried out in the evening, when there is no scorching sun. The earth must be moistened in advance so that the seedlings take root more quickly.

10 days after planting, you can carry out irrigation work. For these purposes, only warm water is used. Its amount is calculated so that about 5 liters of water fall on 1 m2.

The ideal time for root feeding is morning. If such work is carried out in the evening, this is fraught with the occurrence of condensation, which remains on the leaves of the plant, thereby causing them great harm. Wait a few hours until the water is completely absorbed into the soil. After that, you need to open the windows in the greenhouse.

Airing will not harm tomatoes. Only need to monitor the humidity and temperature. The daytime temperature in the greenhouse should be about 25 ° C, but in the evening it can drop to 15 ° C.


Proper planting and proper watering are very important for any crop. Especially for young seedlings, because their immunity, development and ripening of fruits depend on this. Each gardener should know the rules for care, so that later there are no unpleasant surprises.
