Growing tomatoes indoors has its own characteristics. Agronomists opt for tall varieties with mid- and late-ripening fruits. A greenhouse crop grows much longer and therefore yields a longer harvest. This is why proper feeding is so important.

Fertilizers
Tomatoes need both mineral and organic fertilizers. In the first case, we are talking about superphosphate, potassium sulfate, urea, ammonium and calcium nitrate, as well as nitroammofosk. Humus and compost are traditionally used as organic matter. It will not be superfluous to introduce organic mineral dressings. They are presented in the form of mixtures based on humus and mineral components. Do not forget about growth stimulants, drugs to increase the number of ovaries and anti-stress supplements. The type and amount of fertilizers depends on the growing season.
Fertilizing before planting
During the preparation of the soil for 1 sq. m is entered:
- humus or compost (bucket);
- wood ash (two glasses).
An alternative to organics will be:
- urea or ammonium nitrate (1 tablespoon);
- a mixture of superphosphate and potassium sulfate (1 tablespoon each.).
Loosen heavy soil with dry grass, leaves or old sawdust.
Top dressing of seedlings before flowering
At this stage, nothing is added to the ground, since all the necessary substances are already in the soil. Tomatoes take root, the aerial part is gradually developing.
In no case should you overfeed the culture during such a period, especially organic matter (infusion of tops, mullein, etc.).
As a result of such an error, powerful bushes will grow, flowering will begin later, and the ovaries will be small and in small quantities. It is allowed to use only rooters and growth stimulants with top dressing on the leaves (immediately after planting the seedlings).
During flowering
You should wait for mass flowering. Tomatoes at such a time require potassium, which is responsible for the redistribution of nutrients to actively growing parts of the bush, i.e. in our case, ovaries. It is important to make up for the lack of other trace elements, therefore, complex compounds are used, for example, sulfate potassium (20 g), superphosphate (10 g, it is better to dissolve it in hot water first), urea (7 g) - in a bucket of water and 1 m sq. landings.
When the ovaries appeared
Due to the fact that the ovaries are not formed all at once, but gradually, tomatoes need to be fertilized in several stages. The main thing is to wait until 2 brushes are formed on all the bushes, and the fruits become larger. At this point, root feeding is repeated with potassium, supplemented with urea and superphosphate. There is a need for calcium, so calcium nitrate is added in an amount of 20 g per bucket of water.
Practical advice. Memo to the gardener
- The more productive the variety, the more nutrition it needs (once a week or ten days);
- with a lack of nitrogen, the lower leaves turn yellow and fall off;
- yellow edging on the leaves is a sign of a lack of potassium;
- violet color of the leaf below - little phosphorus.
