Topping tomatoes after planting

Growing tomatoes is a laborious process. In order to get tall fertile bushes, it is important that the seedlings are fed with useful trace elements. This problem is solved by feeding tomatoes after planting.

Topping tomatoes after planting

You should understand how tomatoes can be fertilized, because the quality and quantity of the crop depends on the correct choice of fertilizers.

What trace elements do culture need?

Fertilizing tomatoes after planting in the soil is just as important as proper planting of bushes, watering and treatment from diseases and pests.

How to feed tomatoes after planting in the ground? When planting seedlings in a greenhouse or in open ground, it is important to observe the highest quality conditions for growing plants. The bush needs to draw strength in the soil, but unfortunately, sometimes minerals are not enough there. The most valuable substances for this crop are:

  • Nitrogen. The role of this element is important for the development of both the bushes themselves and the fruits of the tomato. Without nitrogen, photosynthesis is not performed. In addition, the lack of this element leads to stunted bushes and to the accumulation of nitrate fruits in the pulp.
  • Phosphorus. An important element for the formation of blossoms and ovaries. Notice his lack of easy. Most often, flowers and ovaries quickly crumble, which affects the yield of the crop.
  • Potassium. It is important for the health of roots, the state of which affects the delivery of moisture and nutrients to all parts of the plant, therefore, with a lack of potassium, tomatoes often get sick, and their fruits do not grow large.

It is not necessary to know what other trace elements tomatoes should receive: tomatoes are annual plants, so the lack of other substances will not significantly affect the quality of the grown crop. In addition, such elements as iron, manganese and copper receive seedlings during preventive spraying from insects and pests.

If you feed the tomatoes after planting, the bushes will be healthy and strong, and the fruits will be large, juicy and healthy. But do not add them in excess: this negatively affects not only the tomato bushes, but also the fruits. A glut of fertilizers makes tomatoes tasteless.

Varieties of Feeding

Without feeding the plant during its growing season, there is a risk of not getting the expected yield. Tomatoes can be fertilized after planting, in front of it and during the flowering period. Planting seedlings in a greenhouse or in open ground, it is fed:

  • organic fertilizers;
  • mineral fertilizers;
  • complex compounds.

Organic type - the most useful for planted culture.


The question of how to feed tomatoes after planting in the ground is most often decided in favor of organic fertilizers. The following substances can be used to fertilize tomatoes:

  • onion peel;
  • baker's yeast;
  • garlic water;
  • bird droppings and cow dung;
  • humus;
  • wood ash and grass.

If cow manure or bird droppings are selected, before use it is necessary to minimize the proportion of nitrogen compounds in bird and cow manure, therefore, such fertilizers are most often diluted and insisted.

Mineral fertilizers are safe and effective. Such formulations can be purchased in specialized stores in the form of liquids, powders and tablets. Gardeners also use wood ash for seedlings before planting and after it, which effectively affects the development of bushes and the formation of high-quality tasty fruits.

How to fertilize

There are two ways to fertilize

After you have decided how to fertilize the tomatoes, choose the method of feeding. There are two ways to feed tomatoes after planting: outside the root (on the bush) and under the root.

Foliar type

The main method is fine dispersion. The nutritional composition that falls on the foliage of the plant is well absorbed by the culture. In addition, the first top dressing is carried out in this way, the purpose of which is to strengthen young shoots and create favorable conditions for the appearance of flowering. In total, up to 4 sprayings can be carried out per season.

The most popular recipe for preparing fertilizer, which is suitable for tomatoes grown both in a greenhouse and in open ground, is a solution of potassium permanganate with urea. To prepare it you will need:

  • 10 l of water;
  • 1 g of potassium permanganate;
  • 15 g of urea.

To preserve the health of the culture and protect them from falling blooms, you can use spraying with the drug "Ovary". An aqueous solution of boric acid (1 teaspoon of the drug per bucket of water) is also suitable.

Root type

Such fertilizer is used no earlier than 3 weeks after planting seedlings.

A combination of organic substances and mineral fertilizers is used. In order for beneficial microelements to be better absorbed by plants, it is important to loosen the soil and cover it with mulch. So, the introduced compositions will more effectively affect the formation of ovaries and the subsequent growth of the fruits.

Gardeners are increasingly trying to avoid chemicals introduced into the fertilizer. Natural product is the safest and most effective.

Feeding steps

To properly feed the tomatoes after planting in the ground, you must follow the scheme:

  • The first feeding of tomatoes after planting is intended to begin the active growth of the bush. It is produced a week after disembarkation. In addition, the first procedure helps to build immunity against diseases and pests. The best option is to use foliar top dressing with a solution of serum, iodine and water.
  • The second top dressing is carried out at the beginning of flowering. It is produced by watering plants. Popular recipe: 1 tbsp. l "Superphosphate", 1 tbsp. l Agricole Vegeta, 1 tsp potassium sulfate, 10 l of water.
  • The third procedure is necessary during the formation of ovaries. A solution is poured along the root, including 10 liters of water, 1 tbsp. le nitrofoski, 1 tbsp. l sodium humate.
  • The fourth fertilizer is applied 3-4 weeks after the third procedure. An aqueous solution of superphosphate (1 tsp of superphosphate per 10 l of water) is poured under the roots of plants.

Other recommendations

  • It is better to apply an insufficient amount of fertilizer than excess.
  • Fertilizing seedlings should be carried out only at temperatures above 15 ° C. At lower rates, substances useful for tomatoes will not be absorbed.
  • Fertilizing under the root is best in the evening.
  • Foliar top dressing is carried out in the morning, in calm weather.
  • From the time of flowering and the formation of ovaries to harvest, the use of pesticides is prohibited.
  • Tomatoes are fed along with watering (root type) and treatment from pests (foliar).

If the plant lacks nitrogen, a matte gray coating forms on the leaves of the seedlings. If phosphorus is not enough, part of the leaf plate turns purple, and if potassium, the leaf edge dries. A lack of copper causes late blight.


How to feed tomatoes after planting in a greenhouse or in open ground? You can make both specialized formulations purchased in hardware stores, and dressings made independently. Tomatoes can be fertilized with bird droppings, cow manure, food waste, dairy products, etc. The main thing is to know the fertilizer formulation and the recommended dosage.
