How to feed tomatoes in the greenhouse

The lack of beneficial elements in the cultivation of tomatoes is one of the most common problems. When growing seedlings, especially after picking or transplanting into a greenhouse, the leaves on the plant begin to wilt, and the bushes themselves fall and look sick. No need to get upset, tomatoes can still be saved.

It is enough to apply the necessary dressing, which effectively affects the culture, activates its further growth.

All dressings are conventionally divided into mineral and organic. There are folk remedies that act no less effectively than powerful drugs. Currently, there are many complexes based on the action of the totality of minerals and organic substances. The combined composition allows not to divide fertilizers on the frequency of application.

Mineral fertilizer use

Mineral supplements include nitrogenous fertilizers, potassium and phosphorus compounds. Mineral supplements are used based on the following schedule: nitrogen - mid-April-early May, potassium - late May-mid June, phosphorus - mid June. This periodicity is explained by the fact that nitrogen provides for the buildup of new shoots, green young leaves, enhances the nutrition of the stem. Potassium and phosphorus affect the flavor components of tomatoes, accelerate fruiting and increase yields.

For the use of nitrogen acquire urea or ammonium nitrate. Dilute a teaspoon of the drug to 10 liters of water and water the tomatoes in the morning. The treatment is repeated after 2 weeks. There are usually enough 3-4 dressings for the bush to straighten and strengthen. With a lack of nitrogen foliage turns yellow, then fertilizing may need more. Immediately after adding the additives to the ground, the soil is slightly loosened for better absorption.

The second ingredient that is needed for tomatoes is potassium. It is used in the form of potassium salt, potassium nitrate. Potassium not only helps to improve the taste of the fruit, but also increases the metal content in the pulp, which is useful for human heart organs. 10 grams of potassium salt is dissolved in a bucket of water and the seedlings are watered at the rate of half a liter of supplement per bush. In the second phase (the 20th of June) it is possible to add phosphorus to potassium. Nutrient mixture is very useful for tomatoes, will provide active formation of ovaries, and fruiting occurs a few days earlier.

Potassium sulfate is introduced not only into the ground, they can also irrigate bushes. Foliar nutrition is diluted in the same proportion as the root supplement. Irrigation of leaves and stem is necessary every 10-14 days.

Attention! Irrigation is carried out strictly before noon, so that in the evening the plants have time to dry. Too late irrigation leads to accumulation of moisture in the leaf axils and the formation of rot.

At the time when fruiting begins, and before it ends (end of August), you can to produce feed of potassium nitrate. To the saltpeter add a tablespoon of superphosphate and water the tomatoes. During the whole season the number of dressings should not exceed 5 times.

Top dressing with folk remedies

A good alternative to the purchase of funds are traditional methods of fertilizing seedlings. They show excellent results and have been used for a long time. Recipes are passed from generation to generation.Constant components in the composition of folk remedies are: ash, nettle yeast, chicken, iodine, compost. Each of the fertilizers is useful in its own way, as it has a rich organic composition and a positive effect on tomatoes.

Watering with ash

The composition of the ash includes minerals, their derivatives, organic acids. The powder can be purchased at the store or collected in the oven by yourself. Especially useful tomatoes ash formed from birch, pine needles, larch. Dilution of the additive is very simple: a glass of ash in 10 liters of water. Insist the mixture for 2-3 days, and then water it with tomatoes. Ash is applied to the leaves of plants, it feeds them with calcium, potassium, fills the balance of elements. Fertilizer is used throughout the summer.


A solution of iodine nourishes and strengthens the immune system of plants, and also scares off diseases and pests. The substance affects the formation of tomatoes and their ripening. The solution is diluted in low concentration, since iodine can cause burns on the leaves and the stem. For breeding on a three-liter jar take 4-5 drops of alcohol iodine. Iodine produces root and foliar feeding.


Even in the garden the yeast has found its application. From them, seedlings are gaining significant growth, the bushes become lush, and the tomatoes sprout quickly and become larger. It is enough to apply 2-3 yeast food for the entire growing season to get a good harvest. They should not be abused either, since yeast has properties to accumulate in the ground and flush out useful minerals and other compounds. A pack of product diluted with warm water (2 liters) and add a teaspoon of sugar. Yeast mixture watered tomato bushes no more than 1 time in 2 weeks.

Important! Instead of yeast, you can use bread rusks or dry buns. In their composition there is yeast.

Nettle infusion

Nettle is considered a very useful plant not only for humans, but also for tomato seedlings. For the recipe is better to use young nettles, which have no seeds. Fill the bucket to the top with freshly mown nettle and pour boiling water. Insist the mixture for 2-3 days, and then diluted in water in a ratio of 1: 1. Nettle infusion can irrigate shoots and water the culture 1 time in 10 days.

Kuryak and compost

Chicken droppings bring to the roots nutrients, from which the seedlings grow well, and fruiting time lasts longer. Kuryak must be diluted with water in a ratio of 1:20. If diluted incorrectly and using too concentrated a solution, fertilizer can seriously harm tomatoes. Kuryak can be watered vegetables until their fruiting. For greater effect after dilution supplement insist 2-3 days.

Composting is also good for tomatoes. Compost can be diluted in water, some gardeners simply mulch them wet earth from watering. Fertilizer is used immediately after transplanting tomato bushes in the greenhouse and until the end of fruiting. It is equally useful in any cycle of cultural life.


Every experienced gardener has his own secrets of growing tomatoes. The main additives for a long time remain watering horse and cow manure, previously diluted in the aquatic environment in the ratio of 1:10. Of the purchased supplements, most gardeners use humate. He is divorced in the amount of a teaspoon into a bucket of water. If the tomatoes are only transplanted into the greenhouse, in a week they are fed with humate and nitrophoska.

According to gardeners advice, you can add a little boric acid or potassium permanganate to the ashes. They are also nutrients for tomatoes and are well absorbed by them. In addition, the compounds have an antibacterial effect, scare away insects and prevent the formation of fungi and viruses on the leaves and stem in the soil.

Nettle infusion is often combined with ash and potassium supplements. They complement and reinforce each other.You can add chopped dandelions to the nettles and a bucket of cow dung or divorced chicken. Infusion of the mixture is necessary under the film, so that fermentation takes place. The concentrated solution is diluted with water in a ratio of 1:10. Water the tomato bushes at the rate of a half-liter jar for 1 plant.

For the prevention of phytophthora, as well as to maintain the immune ability at a high level, tomatoes are watered with whey. A liter of serum is mixed with 9 liters of water; 20 drops of iodine solution are added to the resulting solution. Dilute the mixture irrigated tomato bushes. This feeding alternate with Fitosporin at intervals of a week. A month later, the bushes will become freshened up, and infection with diseases no longer threatens.

The use of additives in the cultivation of tomatoes has a positive effect on the future harvest. Fruits are harvested with a sweet taste, larger, and their number increases markedly. However, feedings do not need to be abused. Excess fertilizer in the soil leads to diseases of the culture, develops the risk of chemical burns. In addition to dressings, they monitor the regularity of watering the seedlings, prune tomatoes from the stepchildren and air the greenhouse. With the observance of the cultivation technique, the time of onset of fruiting is reduced by 2-3 weeks, and the quality of the fruit is kept at the highest level.
