Carrying out the procedure of feeding tomatoes in the greenhouse

Feeding tomatoes in the greenhouse requiresvegetable grower of certain knowledge and effort, as this type of growing vegetables has dramatic differences from the method of growing outdoors. When caring for vegetables grown in the greenhouse, it is necessary to observe the conditions of irrigation, the mode of temperature in the greenhouse and the mode of feeding the planted plants.

After growing or acquiring planting material, it is planted in a greenhouse, and the gardener immediately has a question about how to feed the tomatoes after planting in the greenhouse.

To decide on the method of feedingTomatoes in the greenhouse after planting should examine the question of why do you need top dressing of tomatoes in the greenhouse. The purpose of the feeding of tomatoes in the greenhouse is to ensure the growth and normal development of healthy plants, as well as obtaining a high yield of high-quality fruits. Top dressing of tomatoes in open ground is different from carrying out top dressing in a greenhouse.

Tomatoes, like all representatives of the nightshade,They are very responsive both to the lack of substances and chemical compounds in the soil, and to their overabundance. These plants react very well to the application of top dressing to the soil and foliar top dressing. Feeding tomatoes in the greenhouse requires a careful approach to the fertilizer application process, in some cases it is better to give less nutrient chemical compounds than to overfeed the plants.


Phosphorus has a great influence on the formation of the root system.

What types of fertilizer are required for tomatoes?

A huge role in the cultivation of plants play mineral fertilizers. For optimal development of the vegetable requires a variety of trace elements, the main ones are as follows:

  • potassium;
  • phosphorus;
  • nitrogen.
  • Phosphorus has a huge impact on the formationroot systems and the normal course of the process of formation and ripening of fruits. In the case of a lack of this trace element, tomatoes begin to absorb nitrogen in a smaller volume. The main symptom of a lack of phosphorus in the soil on which the plant grows is the appearance of spots on the lower surface of leaf blades that have a reddish-purple hue. In addition, with a lack of phosphorus, the leaf plate is twisted along the central vein. All listed signs are accompanied by a slowdown in fruit ripening.

    Potassium has a positive effect on the formation process.plant stems and is involved in the process of assimilation of carbon dioxide in the implementation of photosynthesis. When a deficiency of this chemical element occurs, nitrogen compounds of chemical compounds accumulate in the lower leaves, which leads to their fading and dying.


    The first top dressing of the tomato after planting in the greenhouse is carried out at the beginning of flowering and the appearance of fruits.

    Very often gardeners are interested in the question ofthan to feed tomatoes grown in the greenhouse when they turn yellow. Yellowing of plants can be triggered by various factors, and the choice of feeding in each case is carried out depending on the primary characteristics that are detected when inspecting tomatoes.

    When should the tomato be fed?

    For the whole vegetation period, dressing tomatoes inpolycarbonate greenhouse is carried out 3-4 times. The first top-dressing tomato after planting in the greenhouse is carried out at the beginning of flowering and the appearance of fruits. Most often, the first feeding of plants is carried out 20 days after landing in the ground. You should know that if the weather is cloudy for a long time, then the potassium absorption process is disturbed in the plant. The most suitable fertilizer is ash - a product of wood combustion. Feeding tomatoes in a greenhouse with ashes helps to balance the content of basic chemical elements in the soil, such as potassium, phosphorus and calcium. The balanced content of these macronutrients helps to prevent the development of diseases in plants.

    The second feeding of plants is carried out in the period of ripening and fruiting. The interval between the conduct of the first and second dressings should be about 20 days.


    Feed the plants you need by watering tomatoes at the root at the rate of 0.5 liters of solution for 1 plant

    After planting in the soil gardenersThey are interested in how to feed tomatoes in the greenhouse during flowering. For carrying out the first top dressing of plants the wood ash solution is ideal. To prepare the solution for feeding you need to stir 1 tbsp. l wood ash in 1 liter of water. To prepare the solution for feeding you should use rainwater, the use of chlorinated water from the aqueduct is unacceptable. Chlorine, which is contained in tap water, leads to wilting and death of plants. Well and river water can also be used to prepare the fertilizer solution. You need to feed the plants by watering the tomatoes at the root at the rate of 0.5 liters of solution per plant.

    During the formation of buds recommendedfertilize plants with humus. This dressing is carried out at the rate of 1 bucket of humus per 1 square. m. Before using the plant humus must be poured abundantly with ordinary clean water. After watering compost is applied. The layer of applied compost should be about 2 cm. Such a layer of compost prevents the rapid evaporation of moisture, will allow to keep the soil moist for about a week.

    At the stage of the formation of fruits, it is recommended to fertilize plants with infusion of nettle. For the preparation of the infusion is best to use untreated nettle seedless.

    Carrying out plant nutrition using folk methods

    Top dressing of tomatoes gives very good results.in the greenhouse folk remedies that are not tested by one generation of vegetable growers. Among the most common folk ways of feeding tomatoes in the greenhouse - the use of chicken manure. To prepare the fertilizer solution, you need to take 1-2 kilograms of chicken manure, pour it into a bucket and fill it with water. The dry weight of the litter takes approximately 1/4 of the capacity. Poured mass should infuse during the week. During this period, the mixture is fermented. After completion of the fermentation process, the resulting solution is diluted with pure water at a ratio of 1:20. For the preparation of a 200-liter barrel of the prepared solution, you will need a bucket of solution for feeding.

    The resulting solution is used for feedingplants both before flowering and during this process. Fertilize at the rate of 0.5 liters per plant. This solution for fertilizing the soil is a strong nitrogen-containing fertilizer, for this reason it is necessary to apply such a solution to the soil after carrying out abundant watering of the plants. This is required to prevent root burns.

    Another means that allows not only to fertilize the soil, but also to disinfect it, is iodine.


    Iodine fertilizer is best carried out in the morning

    The solution with this chemical can be applied both on the root system and on the aboveground part of the plant.

    To prepare the solution for processing plants1 to 3 ml of iodine is required and dissolved in 10 liters of water. The amount of iodine depends on the surrounding temperature. In the prepared solution is added 1 liter of milk or fermented kefir.

    This solution is recommended to be applied after the start.fruiting process. Using this mixture as a top dressing allows you to increase the quantity and quality of fruits. The solution allows high-quality disinfection of the soil from various pests. When making the solution in the soil should be used 0.5 liters per plant. In case of a lack of potassium in the soil, one tablespoon of potash fertilizer can be added to the mixture.

    For cooking, use distilled water with a temperature of about 22 ° C. Fertilizer iodine is best done in the morning.

    Conducting foliar dressing of tomatoes

    To implement foliar feedingplants selected chemicals that have good solubility in water. Such compositions should contain a complex of micro-and macro. Foliar feeding is useful during the fruiting period. The process of foliar feeding is best done in the evening. Since the implementation of feeding in the morning, the subsequent daily warm-up contributes to the rapid evaporation of moisture and does not allow to achieve the corresponding result. Favorable weather for carrying fertilizer is considered overcast. The effect of using the solution can be seen already after 2-3 hours after application.


    To prepare the fertilizer solution, take 1-2 kilograms of chicken droppings, pour them into a bucket and fill with water

    This type of feeding is especially effective.in identifying the weak development of shoots with nitrogen starvation. It should be remembered that at a soil temperature of 14 ° C, the root system of the plant ceases to develop. When such a situation arises, it is optimal to apply a top-dressing by spraying the foliage.

    Spraying the nutrient solution followscarry out in such a way that it does not occur from the plate. Using this method of feeding allows you to increase the sugar content in fruits.

    Very often vegetable growers to conduct foliartop dressing use boric acid. The use of this chemical compound allows to improve the nutrition of the ovary and allows saturating the developing fruits with sugary substances. For work preparing a solution that contains 5-10 g of boric acid in 10 liters of water. Spraying the prepared solution is carried out at the rate of 1 l per 10 sq. M. m

    The advantage of this type of feedinglies in the fact that through the leaves the plant absorbs only those elements that it lacks. Another advantage of foliar feeding is getting quick results from the use of fertilizer. The effect of fertilizer application manifests itself literally several hours after spraying. When using root dressing effect appears only after 2 weeks.

    Use of yeast for feeding

    Yeast is very effective.fertilizer, since the content of protein compounds in them is about 65%. The use of top dressing tomato in greenhouse with yeast allows to compensate for the lack of organic iron, minerals, macro- and microelements in the soil.

    Many gardeners know about the high content of compounds useful for tomatoes in yeast, but not all vegetable growers know how to properly feed tomatoes with yeast in a greenhouse.

    Besides these benefits, yeasts areAn excellent growth stimulant. The use of yeast contributes to the growth of the root system. Activation of growth processes in the root system contributes to the development of a healthy and strong above-ground part of the plant. Plants that are fed with a solution containing yeast become stronger and more durable. When conducting the feeding with yeast, the seedlings will transfer the picking more easily.

    Feeding with yeast solution can be onany stage of plant development, but it will be especially effective for seedlings. The use of yeast starter for fertilizer in the process of fruiting allows you to increase the quantity and quality of fruits.

    Soil fertilizer under the tomatoes with the help of leaven,the basis of which is yeast, is widely used by vegetable growers who seek to obtain environmentally friendly plant products. The use of yeast top dressing allows preserving vitamins and beneficial compounds in tomato fruits as much as possible.


    Feeding with yeast solution is possible at any stage of plant development.

    200 g is used to make the leaven.Baker's yeast in 1 liter of water. After the fermentation process, add water, the volume of the solution is adjusted to 10 liters. The fermentation of the starter process usually lasts a day, after which the diluted solution can be used for its intended purpose.

    Feeding with yeast is carried out 2 times during the growing season. Most often, the fertilizer is first held a month after planting and the second time in mid-summer.
