Top dressing tomato: how to fertilize seedlings?

The first and very important step is to grow healthy seedlings. Before planting the plants in the greenhouse, they need to be fertilized with yeast. They will provide the seedlings with the necessary nutrition, accelerate their growth and fruit formation.

Yeast fertilizer

It is not difficult to prepare it, for this you need: 1) One sachet - dry yeast; 2) Two tablespoons - sugar; 3) One glass - warm water. Mix all this thoroughly and let it brew for a couple of hours. Dilute the infusion, like this: five hundred milliliters of the mixture per ten liters of water. With the concentration that you get, you can safely water the bushes.

In the spring, when you dig up the soil, you need to feed it, especially if you did not do it in the fall. On the beds and holes, you need to add one bucket of peat and turf soil for each square meter. Then add organic matter: 1) Five hundred grams - wood ash; 2) Ten liters - rotted compost, or organic humus; 3) One teaspoon is urea. All these calculations are per square meter.

What to feed tomatoes after planting in greenhouse conditions

At the end of the spring, beginning of the summer period, a few days after you plant the tomatoes, the seedlings need to be fertilized with the help of complex dressings. Such feeding should contain: 1) Nitrogen; 2) Phosphorus; 3) Potassium. But it is important to remember that in greenhouse conditions the percentage of moisture is higher than in open areas, and therefore all nutrients are absorbed much faster. It is important that the plant has time to absorb them, for this you need to slightly reduce the concentration.
For example, the solution can be as follows: 1) One tablespoon - nitrophosphate; 2) Five hundred milliliters - mullein; 3) Ten liters - water. You need to add one liter per bush.

What to feed tomato bushes during the flowering period

During the flowering period, tomatoes can be fertilized with the "Sudarushka Tomato" fertilizer. It contains all the essentials: 1) Nitrogen - thirteen percent; 2) Phosphorus - eight percent; 3) Potassium - eight percent; 4) Zinc - fifteenth of a percent; 5) Manganese - two percent; 6) Cobalt - four hundredths of a percent; 7) Copper - one tenth of a percent; 8) Molybdenum - four hundredths of a percent; 9) Boron - one and a half percent. And what is most remarkable, this fertilizer does not contain such a substance as chlorine.One teaspoon of fertilizer should be diluted in ten liters of water, after which five hundred milliliters should be allocated for each plant. This top dressing can not only increase the percentage of the crop, but also protect the plant from fungal infections.

DIY recipe

To do this, you need to take: 1) One tablespoon of potassium sulfate; 2) Five hundred milliliters - bird droppings; 3) Ten liters - water; 4) Five hundred milliliters - liquid mullein. All this must be thoroughly mixed, and then add about a liter of solution to each bush.

Top dressing tomato in a greenhouse: foliar dressing

This is a very important part during the period of ovary formation. In the evening, or in cloudy times, a solution with wood ash should be distributed over dry foliage. For such a solution you need: 1) Two glasses - wood ash; 2) Two liters - hot water. After stirring the solution, you need to let it brew for a couple of days, then you need to filter. After that, the volume of the solution must be increased to ten liters, and then start spraying.
Most varieties respond well to magnesium sulfate feeding. Fifteen grams of this dressing, you need to dissolve in ten liters of water. Why spray plants, adhering to the ratio: one and a half liters per square meter. You can also treat it with superphosphate - stir one teaspoon in ten liters of water.

The best feeding option for the fruiting period

When the tomatoes begin to bear fruit, they are fed one last time. Two tablespoons of superphosphate must be dissolved in ten liters of water, and also one tablespoon of potassium humate must be added there, in liquid form. You need to apply at the root, about one liter per bush. For the formed fruits to be tasty and juicy, they must be saturated with boron, manganese, iodine and potassium. It is not difficult to prepare such a top dressing, you just need: 1) Ten grams of boric acid; 2) Ten milliliters - iodine; 3) One and a half kilograms - sifted wood ash; 4) Ten liters - water. When feeding, you need to allocate one liter for each bush.
But it is important to remember that as soon as the fruits appear, only root fertilizers can be used.

Top dressing tomato: what you need to feed for a better harvest

In order for the seedlings not to stretch, the shoots are strong, two weeks after planting, they need to be fertilized. For this you need: 1) Ten liters of water; 2) Twenty grams - superphosphate; 3) Thirty grams - ammonium nitrate; 4) Fifteen grams - potassium sulfate; 4) Wood ash must be added at the rate of one glass per liter. Repeat after two weeks.

What to feed tomato bushes for active growth and development

Seedlings can grow slowly, so they need to be fertilized with sodium humate. It must be diluted in accordance with the instructions, and applied at the root of the plant.
If the seedling does not grow shoots well and the foliage turns yellow, then it probably lacks nitrogenous elements.

The number of dressings during the period of active growth and development

They cannot be named with perfect accuracy, here you have to build on the variety and the plant itself. Usually, normally developing crops are fed three to four times.
If the plant is sick, or lags behind in development, then it needs to be fertilized every two weeks, alternating the type of dressing.
