When do tomatoes need feeding?
It's crucial to remember that tomatoes require additional nutrition, which is why they are fertilized not only during flowering and fruiting, but also during the spring period of active growth. Commercial fertilizers, which contain a comprehensive range of nutrients, are used for this purpose, but homemade fertilizers are also quite suitable.

They are no worse than store-bought fertilizers, and in some situations, homemade fertilizers are even better.

In fact, this type of feeding isn't done just once, but three times. First, the yeast mixture is added when the plant is just being planted in the greenhouse. After a couple of weeks, this type of fertilizer can be used. Only then can you decide what to feed it with. tomatoes in a greenhouse, because it is the yeast feed that is used at these stages of tomato development.
To prepare the solution properly, use a pressed yeast block, not the kind sold in packets labeled "fast-acting." You'll need just fifty grams of this yeast per bucket of clean water. Stir the resulting solution thoroughly to disperse the yeast, then leave the mixture for a couple of hours to allow the yeast to begin to activate. Once this time has passed, you can fertilize the soil where your tomato plants are growing.
Complementary food made from pharmaceutical iodine

To prepare this fertilizer, use no more than ten grams of iodine per bucket of water (no more than ten liters), add a teaspoon of pharmacy iodine, and mix thoroughly.

Use no more than half a liter of this solution per plant, and fertilize every two weeks after planting the seedlings in the greenhouse soil.
Using wood ash as fertilizer
This fertilizer is most often used not only during the flowering and fruiting stages of tomato production, but throughout the entire growing season. Combining ash with other additives can help you achieve a truly large harvest in a short period of time, strengthen the plant's root system, produce larger and juicier fruits, and generally increase the number of ovaries per plant. This type of fertilizer is especially important when the plant's leaves and stems begin to thin.

The key here is not to overdo it with fertilizers, otherwise you can only make things worse. Fertilizing with iodine is new to me; I'll try it next year. But for several years now, I've usually been fertilizing with yeast, although this can only be done twice a season. To do this, I take one packet of instant yeast, add two tablespoons of sugar, and a little warm water. I let it sit for two hours to allow it to rise. Then I pour this mixture into a bucket of water—we should add half a liter of this wonderful solution per watering can—and in three days, the effect will be noticeable.
