How to feed tomatoes after planting in a greenhouse and open ground

Things to remember when feeding tomatoes after planting

• Try to fertilize at sunset or early in the morning before the sun is out. Products exposed to bright light can burn the leaves of plants.
• To avoid burns to the root system, pour top dressing into moist soil. First, moisten the soil with plain water, and then with a nutrient solution.
• Pour fertilizer strictly under the root, trying not to get on the leaves and stems. This will help prevent not only burns, but also decay, as well as the appearance of fungal diseases.
• If you do not want to prepare nutrient mixtures yourself, use ready-made complex fertilizers for tomatoes, eggplants and peppers. Mineral, organic or organo-mineral formulations can be found in stores and garden centers. The costs and method of application are indicated on the packaging.
• You can feed tomatoes only with mineral or only organic fertilizers, or alternate them at different stages. The main thing is to choose only one solution during the next procedure and not mix different ones, so as not to destroy the plants.

• Carefully follow the dosage of fertilizers. It is better to make a smaller concentration - it's not so scary. But due to excessive nutrition, tomatoes can develop inferiorly or even die.

When to feed tomatoes in the greenhouse and open field

During the season, three top dressings will be needed.

• The first is carried out approximately two weeks after planting seedlings to a permanent place.
• The next time fertilizers are applied when the bushes began to actively bloom.
• Then the plants are fed at the fruiting stage, when a lot of green tomatoes have already started on the plant.

At the same time, do not delay with the final feeding. Any such procedures should be stopped approximately 2 weeks before the harvest of the main part of the crop.

How and what to feed tomatoes two weeks after planting in a greenhouse or open ground

Plants have suffered stress from adaptation and need complex nutrition, which will contain the main macronutrients: nitrogen, phosphorus and potassium.

Mineral fertilizers

Prepare any of the nutrient solutions and water the tomatoes under the root. One plant will need 0.5–0.7 liters of the mixture.

• In 10 liters of water, dilute 25 g of ammonium nitrate, 40 g of superphosphate and 15 g of potassium sulfate.
• Dissolve 1 tablespoon of nitrophoska in 10 liters of water.

organic fertilizers

Due to the high nitrogen content, natural fertilizers will help the bushes quickly start growing and get a powerful green mass. Make one of the solutions and pour the tomatoes under the root at the rate of 0.5 liters per plant.

• In 10 liters of water, dilute 0.5 liters of liquid mullein, which can be found ready-made in stores and garden centers.
• Pour 10 g of dry yeast and 2 tablespoons of sugar into 250 ml of warm water, mix thoroughly and leave the mixture in a warm place for 2 hours. Then dilute the infusion with 10 liters of water and use.

How and what to feed tomatoes at the beginning of flowering

At this stage, plants especially need potassium, which is responsible for lush flowering and setting. fruits.

Mineral fertilizers

Choose any of the compositions and pour 0.5–1 l of nutrient solution under each bush.

• In 10 liters of water, dissolve 1 tablespoon of superphosphate and 1 teaspoon of potassium sulfate.
• In 10 liters of water, dilute 10 g of potassium nitrate and 25 g of magnesium sulfate.
• Dissolve 15 g of potassium monophosphate in 10 liters of water.
• Dilute 10 g of potassium magnesia in 10 liters of water.

organic fertilizers

At this stage, it is better not to use infusions of cow dung or bird droppings in their pure form. A high concentration of nitrogen in the composition of such fertilizers will stimulate the active growth of bushes. As a result, they will spend energy on increasing green massrather than fruit set. Therefore, prepare any of the mixtures with a high content of potassium, phosphorus and other useful substances.

• Pour 200 g of wood ash into 2 liters of hot water. Mix thoroughly and let stand at room temperature for two days. Then strain the solution through cheesecloth and dilute it with 8 liters of water. Spray the leaves of tomatoes with the resulting product in the evening or early in the morning.
• Dissolve 1 teaspoon of boric acid in 10 liters of water. Sprinkle this mixture on tomato leaves in the evening.
• In 10 liters of water, dilute 1 tablespoon of liquid potassium humate. Water the plants under the root. Each seedling will need approximately 1 liter of the mixture.

How and what to feed tomatoes in the fruiting stage

Feed the plants high potassium and phosphorus mixtures to keep the fruits juicy and fleshy.

Mineral fertilizers

Choose one of the solutions and pour about 1 liter of the mixture under each bush.

• In 10 liters of water, carefully dilute 1 tablespoon of superphosphate.
• Dissolve 1 tablespoon of potassium sulfate in 10 liters of water.

organic fertilizers

You can use the same solution of potassium humate that was done during the second top dressing (1 tablespoon per 10 liters of water). Pour 1 liter under the root of each tomato.

Another option is to prepare a more complex fertilizer from several components. To do this, dissolve 10 ml of iodine and 10 g of boric acid in 10 liters of water, add 750 g of wood ash and mix thoroughly. Dilute 0.5 liters of the finished solution with 10 liters of water. Feed the tomatoes by pouring 1.5–2 liters of the resulting mixture under one bush.
