Watering a tomato in the ground and in the greenhouse. How to water the tomatoes and what? Watering with milk, iodine and yeast


Tomato is a popular and widespread crop, suitable for growing in different latitudes, both in open ground and in glass, film or polycarbonate greenhouses. The vegetable is no different to the high capriciousness, but it still requires some attention. To get on the site a bountiful harvest of beautiful, large fruits, feeding alone will not do. It is very important to establish a full-fledged, high-quality watering of the tomato at all levels - from seedling to an adult plant - and provide them with a comfortable environment for growth and fruiting.

How to properly water the tomatoes in open ground and greenhouse

Watering bushes with buckets, bottles or a hose, it is necessary to direct the jet strictly under the root and watch very carefully that the water drops do not fall on the foliage and trunk. Too often it is not necessary to moisten the soil.For greenhouses, where the land under planting is well mulched, one abundant watering per week is enough.

Vegetables growing in an open garden need more frequent water procedures. During the period of hot, dry summer, it will be necessary to pour one standard bucket of water under each bush every 2-3 days. It is better to do this in the evening, so that the life-giving moisture is absorbed into the ground, rather than drying out under the bright and scorching sun.

How to water the tomatoes to feed them

In order for the bush to develop properly and form strong ovaries, it is recommended to feed the young seedlings a little and pour it with a nutrient solution of iodine and water once. But to protect the plant from common pests will help a mixture of milk and iodine. Liquid need to spray the bushes on top in late May or early June. After this treatment, a thin film will appear on the tomatoes, preventing the larvae and pathogens of all kinds of diseases from penetrating into the leaves.

We pour tomatoes with milk, iodine and yeast


  • Yeast is an organic product and is often used as a top dressing for vegetable crops. To prepare a healing mixture for watering a tomato in the ground, take 1 kilogram of briquet yeast and dissolve them in 5 liters of water at a pleasant room temperature.Then the young tomato bushes are watered with the active liquid. This is usually done at the end of May, when the weather is warm and there are no frosts on the ground even at night.
  • Iodine contributes to the formation of ovaries in a tomato and has a beneficial effect on fruiting. A weak solution (2 drops per 4 liters of warm water) is once watered young seedlings shortly before planting in the ground. After this treatment, the bushes develop faster and form neat inflorescences with a well-branched structure.
  • Milk has a unique composition, rich in all sorts of useful substances. Together with water and iodine it is used as an effective top dressing for tomatoes. To prepare, mix 4 liters of water with 1 liter of raw milk and at the end add 15 drops of iodine. The solution is sprayed with bushes in early June. If a phytophthora has started on the site, the milk component is changed to serum and tomatoes are treated with this mixture.

How often should I water the tomatoes?

How often to water a tomato to get sweet, juicy fruit with a fleshy, elastic flesh? The answer to this question is not as complicated as it seems at first glance.Gardeners with experience say that the bushes need to be wetted plentifully, but rarely. Constant watering in small doses will only harm the plant and will necessarily inhibit the growth of seedlings and its normal development.

In addition, an excess of water will significantly raise the level of air humidity (from the optimal 50% to the destructive 80%) and sharply reduce the temperature of the soil. Young shoots will no longer actively go up, some flowers fall off, and the number of ovaries that form will decrease significantly. Taking into account all the above facts, we can assume that the bushes of tomato will be enough for abundant, but not excessive watering no more than 1-2 times a week.

Watering a tomato in a greenhouse: how to water the tomatoes correctly


Watering a tomato in a greenhouse requires a proper and balanced approach. At the time of planting the seedlings, it is necessary to soak up the prepared holes (1 large watering can each) very abundantly with moisture, and then water the young bushes directly under the root (1/2 watering can). The best is considered to be water with a temperature of + 18 ... + 22 ° C. After moisturizing procedures, fresh planting should be done with dry straw, hay or any other natural material at hand.

The next act of watering is carried out only after 10 days (1 watering can under each bush). Then seedlings can be left alone until the moment when there are no ovaries on it. Experiencing a lack of moisture is not needed. Mulch will reliably keep it in the ground and tomatoes will be enough food for high-quality and fast, full growth.

When the fruits on the tomatoes are tied, the mode of watering in the greenhouse will change somewhat. “Water” plants will have no more than once every 7-10 days (of course, in the presence of mulch, which protects the soil from drying out). In this embodiment, the fruits on the bushes ripen juicy and record large.

Watering a tomato in a polycarbonate greenhouse

In a polycarbonate greenhouse, the total internal temperature is always several degrees higher than in similar light structures made of glass or film. Therefore, the break between the moisturizing procedures should be shorter and the water should simply have a comfortable room temperature (approximately + 20 ° C). Experienced gardeners do not recommend watering plants directly from a well, central water supply or a well. Abuse of water is also not worth it, because in this case the plants will start to curl the leaves, and excessive moisture in the greenhouse will necessarily lead to the appearance of phytophthora.


So that the air inside does not lose dried out too much, you can put a barrel of water among the tomato bushes. Just do not forget to cover it with plastic wrap, otherwise the atmosphere will become too wet and provoke the development of mold diseases on plants.

How to properly water tomatoes: tips and tricks


Watering a tomato is a serious moment to which you need to approach very responsibly. It is almost impossible to determine a universal and suitable standard for the amount of water. For proper hydration it is necessary to take into account such positions as:

  • growing conditions;
  • specific characteristics of the variety;
  • seasonal weather conditions.

In order for the plant to fully develop both in the greenhouse and in the open field, the soil moisture should be about 85-90%, and the air humidity should be from 45 to 50%. Under such conditions, the tomatoes will grow well and eventually give a bountiful harvest.


Regardless of how watering is carried out (from a watering can, hose or bottles), water should be sent only under the roots of plants or into the grooves between the bushes. Not a single drop should fall on the sheets, fruits and stems, otherwise plants in the sun can get burned in the sun.In addition, when the upper irrigation or drip irrigation significantly increases the humidity, and this contributes to the development of various fungal diseases that significantly reduce the yield of solanaceous crops.

Often, watering tomatoes can not be in the greenhouse, or in the garden. Particularly careful with moisture should be at the moment when the weather is cool, cloudy and damp. At this time, it is necessary to reduce water procedures to a minimum, until stable, sunny, clear days are established.

To make bushes feel good, develop evenly and are not damaged by diseases and insects, you can add natural ingredients (iodine, yeast, milk, etc.) to the water and water the tomatoes with this nutrient mixture. It acts on plants much better than industrial, chemical agents and does no harm to the quality of the ripening fruit.
