Heat-loving tomatoes are often grown in a greenhouse. There they receive protection from bad weather, cold. But the soil in such a structure is quickly depleted. For a good harvest, the correct feeding of tomatoes after planting in the greenhouse is important.

Important elements for tomatoes

The soil should contain all the nutrients necessary for the growth and ripening of tomatoes.

For fertility, the earth needs:

1. Potassium. To normalize the water balance. This substance helps the plant to absorb moisture, deliver it to the upper parts, promotes the development of the root system, and increases resistance to drought and disease.
2. Bor. Promotes an increase in the number of ovaries on the bush, especially if the summer is cold and rainy.
3. Phosphorus. Helps the root system to consume nutrients from the earth, participates in the process of photosynthesis.
4. Calcium. Promotes the process of cell division, is especially useful for plants at the initial stage of development.
5. Nitrogen. Accelerates the process of cell division, enhances the growth and development of tomatoes.
6. Magnesium. It is considered the main element of photosynthesis.

Without proper, timely feeding, the plants in the greenhouse will not be able to receive these important elements. Adequate nutrition helps them to resist fungal diseases, prolongs the period of fruiting.

Top dressing rules

With the correct fertilization, the plants will feel good, adapt faster, and begin to actively develop. You must follow the rules:

• feeding should be done in the morning or evening;
• during the day, you can apply fertilizers only in cloudy weather;
• before applying top dressing, the beds should be well watered;
• for one well, you need to prepare at least 500 ml of top dressing;
• regular feeding in the greenhouse is important, after about 1-2 weeks;
• it is necessary to apply fertilizers at a temperature of 20-25 ° C, phosphorus and nitrogen are not absorbed in the cold, an ovary does not form at high temperatures;
• it is recommended to regularly ventilate the greenhouse;
• in different phases of growth, certain types of feeding are used;
• you need to strictly adhere to the recommendations for the amount of fertilizers in percentages indicated in the instructions.

No special feeding skills are required. The dosage must be observed. When fertilizing, you cannot act according to the principle "the more the better". This can kill the plants.

Folk remedies for tomatoes

You can feed tomatoes with folk remedies after planting in a greenhouse. They are simple, affordable, non-toxic, and show good results.

Onion peel is considered a universal remedy for tomatoes. It can be applied at all stages of crop growth. A decoction of onion peels is able to strengthen the roots, disinfect the earth, and prevent the development of numerous diseases.

For root feeding, you need to take onion peel (1 glass) and water (1 bucket), mix, bring to a boil, cool and water.

For spraying, prepare a solution at the rate of 2 cups of onion peels per 1 cup of hot water. Mix and leave to infuse for 3-4 days. Add 2 more cups of water and a little laundry soap to the mixture for more firm adhesion to the surface of the leaves.

The gardeners received good reviews for feeding tomatoes after planting in the greenhouse with yeast. They contain many nutrients that strengthen all parts of the plant. They quickly activate microorganisms, which by their vital activity and structure the soil.

For a yeast solution, 100 g of raw yeast is required. They must be diluted in warm water (1 l), left to infuse for 3-4 hours. You will get a concentrated mixture, which is enough for 5 buckets of water. If you take dry yeast (10 g), then they are stirred in 200 ml of water, sugar (5-10 g) is added, also insisted, then diluted with 10 liters of warm water.

If you constantly plant tomatoes in the greenhouse, then the soil needs to be changed annually.

If the soil in the greenhouse is only disinfected but no minerals have been added, iodine deficiency may occur. This threatens with late fruiting, a tendency to various diseases. Fertilizing tomatoes after planting in the greenhouse with iodine is carried out 2 times.

The first time - fertilize the cut seedlings after the appearance of 4-5 leaves. One drop of iodine is dissolved in water (3 l), each glass is poured. Another time it is fertilized at the stage of the formation of the fruit brush - 3 drops of iodine are dissolved in water (10 l). Each bush takes 1 liter of solution.

Herbal infusions are considered a good fertilizer. They can be prepared from any grass, weeds that grow in the backyard. The best component of this infusion will be young nettle. In a barrel with a volume of 100 liters, you need to put 9-10 kg of grass, add 8-9 liters of cow dung. If it is not there, then 0.5 liters of old jam can be replaced with slices of bread.

Pour everything with a bucket of hot water, then cold, close and leave to ferment for 7 days. Then add 1 liter of wood ash, mix well. A liter of green mixture is diluted with a bucket of water, tomatoes are watered at the rate of 1.5-2 liters for each bush.

Fertilization with urea

Fertilizing tomatoes after planting in a greenhouse is useful to do with urea. It is needed for the good development of seedlings, strengthening the root system, and increasing plant productivity. Fertilizer consists of 50% nitrogen. With its deficiency, the fruits undergo deformation, the leaves turn yellow, fall off.

Advantages of urea:

• completely soluble in water;
• excess harmful substances evaporate;
• does not contribute to the accumulation of nitrates in the ground and fruits;
• helps the growth of vegetative mass;
• prevents the development of diseases.

The fertilizer solution for use must be warm so that it is better absorbed by the plant. It is imperative to observe the dosage. Exceeding the norm can lead to plant burns.

20 g of urea is sufficient for 1 m². To prepare a solution for irrigation, you need to take 20 g of fertilizer and 10 liters of water. A different solution is prepared for spraying. For 30 g of urea, 10 liters of water are needed. You can use 20 g of fertilizer and 5 liters of water. One bush takes 1 liter of the mixture.

Unique spray solution

Experienced vegetable growers feed the tomatoes after planting them in the greenhouse with iodine and milk. This helps plants to grow actively, develop well, and protect themselves from pests and most diseases.

Milk contains many trace elements that are useful for the growth of tomatoes. It contains calcium, potassium, phosphorus. Milk contains lactose, which is not to the taste of many pests. After treatment, a film forms on the plant, which saves the bushes from diseases.

The solution is easy to prepare. You need to take a bucket with a volume of 10 liters, pour raw milk (1 liter), add iodine (20 drops). Mix well. Spray tomatoes with this solution in dry weather without wind.

To get rid of phytophthora, you need to dilute iodine (15 drops) in raw milk (1 liter). Spray the bushes. Processing can be carried out several times. Tomatoes will grow better, milk with iodine is a good natural fertilizer for them.

Feeding Tips

Experienced vegetable growers by the appearance of the bushes can determine what substance the plant lacks. Beginners should heed the advice of an agronomist in order to timely feed the tomatoes with the necessary composition:

1. With a nitrogen deficiency, plant growth slows down or stops altogether. The lower leaves turn yellow, the young ones fade at the tops. In this situation, fertilization with urea will help.
2. Tomatoes grow thin, stretch strongly with calcium deficiency.
3. The lack of potassium betrays itself by curling the upper leaves, the manifestation of a dark border. The root system in such cases will be weakened, the fruits will grow small or medium in size.
4. If there is not enough phosphorus, then the underside of the leaves becomes bluish.
5. With iron deficiency, the leaves turn pale, and the veins acquire an intense green color.

If the tomatoes look healthy, develop correctly and quickly, then you can skip the next feeding or use a less concentrated solution, because an overdose of fertilizers negatively affects the soil and plants.

Outcomes

Tomatoes are good to grow in greenhouses, most vegetable growers do this. But the soil needs to be constantly fertilized, as it is quickly depleted. It is necessary to feed the tomatoes several times after planting in the greenhouse, otherwise they will grow poorly, start to hurt, and give a poor harvest. Folk fertilizers are simple, effective, non-toxic. Top dressing is best applied to wet soil.
