How to feed tomatoes during fruiting in a greenhouse: the best formulations and instructions for the procedure

Through winds, heavy rains, thick fogs - all this is typical for the northern regions of Russia. How to grow a rich and tasty harvest of tomatoes in such conditions? The answer is simple: install a greenhouse on your summer cottage.

In addition to protection from bad weather, the greenhouse provides vegetables with the necessary temperature conditions and degree of lighting. And in order for the number of ripe tomatoes to increase, mineral and organic fertilizers are added to the soil during the ripening period.

Feeding tomatoes

During the fruiting period of tomatoes pay increased attention to fertilizing. The taste of vegetables, as well as the degree of keeping quality and shelf life depend on their quality and quantity.

Specifics and features of the procedure

As soon as the fruiting period begins, remember the main features of the organization of fertilizing:

1. When feeding tomatoes during this period, be careful with nitrogen-containing fertilizers. The fact is that the entire effect is spent on the growth of green mass, as a result of which the tomatoes themselves are left without nutrition. Their formation and growth slows down.
2. Don't forget to reduce the amount of water for irrigation. Add aloe juice or a solution based on onion peels to the water. This will help prevent plant growth from slowing down.
3. Prepare fertilizers containing potassium, since at this time the tomato especially needs it. Avoid fertilizing with potassium chloride, because tomatoes do not tolerate potassium levels in the soil itself.Feed carefully, observing dosages.

The role of macroelements in the development of tomatoes

Macroelements are necessary for all plants, regardless of where they are planted. Let's look at what each element is responsible for and what its significance is in the development of a tomato.

Nitrogen

Needed by bushes for the development of green mass. The lack of nitrogen leads to the fact that the leaves do not grow and have a dull appearance. The upper leaves do not curl, older plates die off and have a dull or faded tint. Because of this, fruiting is delayed. Nitrogen-containing fertilizers correct the situation.

For example, use a solution of 20 liters of water, 1 liter of mullein and 2 tablespoons of nitrophoska. Water the plants at the rate of 0.5 liters of liquid per 1 bush. It is best to fertilize bushes in the morning or evening.

Such fertilizing is carried out no more than 2 times a month. Also, nitrogen fertilizers often contain phosphorus. It helps the bushes tolerate the cold more easily. A lack of phosphorus causes the leaves to turn purple. We'll talk more about this below.

Important! With normal nitrogen content, the leaves have a color and size characteristic of each variety. In the morning the top curls, and in the afternoon it becomes straight.

Phosphorus

During the fruiting period, with a lack of phosphorus, the leaves appear brown spots in the areas between the veins. An excellent remedy is superphosphate extract. Pour 2 tablespoons of superphosphate into 1 liter of boiling water and leave overnight. Next, increase the volume to 10 liters by adding water and water the beds. Sometimes gardeners use a simpler method and simply pour 0.5 teaspoon under each bush.

Compost with the addition of wormwood is used as an organic phosphorus fertilizer.When applying phosphorus on acidic soils, it is necessary to first lime the soil. To do this, 1 month before fruiting, wood ash or lime is scattered on the beds.

Potassium

Potassium deficiency appears as a brown rim along the edge of the leaf. The leaves curl into a tube and bend upward. Potassium fertilizers have a beneficial effect on plant metabolism. A valuable source is wood or stove ash. The fertilizer is suitable for absolutely all types of soil, regardless of the acidity level. In addition, the ash does not contain chlorine, which is very harmful to tomatoes.

Banana peels are also used as a source of potassium. One banana contains about 0.5 g of potassium. Simply collect the skins and add them to your compost. Bananas also contain calcium, magnetism and phosphorus.

Magnesium

Signs of magnesium deficiency include light spots on the leaves, white veins and weak leaf blades. To correct the situation, use magnesium sulfate. It also contains sulfur, which is necessary for normal plant growth.

When applying fertilizer, be sure to follow the dosage and instructions for use. After applying magnesium in dry form, be sure to water the beds, because magnesium sulfate is not active in a dry environment. The drug goes well with products containing nitrogen and phosphorus.

After using the drug, the ripening of tomatoes accelerates, productivity increases and taste characteristics improve. Plants absorb calcium, nitrogen and phosphorus better.

The order and stages of the procedure

The organization of feeding is as follows:

• preparation of applied fertilizer;
• if the soil is dry, then moisten it with a small amount of water before fertilizing. Melt or rain is best suited for this.The water temperature should be at least 20 degrees;
• ventilate the greenhouse - the plant needs fresh air;
• Fertilize each bush separately.

It is better to fertilize early in the morning so that the nutrient solution or powder is absorbed by the evening. Leaves, stems and tomatoes should be dry at night. Otherwise, the risk of developing fungal infections increases.

Types of fertilizing

How to feed tomatoes during fruiting in a greenhouse? Depending on the method of application, there are root and foliar fertilizers. The root method is the most popular. He saturates tomatoes with vitamins by watering them at the root.

Foliar feeding is applied directly on top of the bush. For its preparation, a weaker concentration is used to avoid burns to the leaves. Both root and foliar feeding are beneficial for plants, especially if they are alternated with each other.

Purchased drugs

Gardeners like to “feed” tomatoes with the following preparations:

1. «Kornevin" The name speaks for itself: first of all, the drug has an excellent effect on the root system of the bush, making it even more developed and powerful. In addition, it reduces the impact of adverse external factors. To work with Kornevin, prepare protective clothing and gloves in advance. Sold in bags of 0.4 g. The price of one package is 11 rubles.
2. «Mortar"contains nitrogen, phosphorus, potassium, as well as other microelements necessary for the plant. Approximately 20 mg of “Solution” is added to the root. It is quickly absorbed by tomatoes and quickly eliminates the lack of any substance. Used as a solution. The price for 0.5 kg is 53 rubles.
3. «Station wagon" Granular fertilizer is effective and accessible to any gardener.The best effect is achieved if you apply it before loosening or watering. Ensures proper absorption of nutrients by tomatoes, low levels of nitrates, and good yield. 5 kg of “Universal” costs 299 rubles.
4. «Orgavit" The basis of the fertilizer is dry horse manure. It occupies a leading position in terms of the content of useful elements. “Orgavit” is practically not washed out of the soil. Available in granule form, non-toxic. Gardeners pay 139 rubles for 2 kg of product.
5. «Vermicompost" It is a liquid organic solution. Contains humic acids, biologically active substances, micro- and macroelements, amino acids. 3 liters of Biohumus cost 199 rubles.

Folk remedies

Popular folk remedies include:

1. Chicken droppings - rich in calcium, potassium and nitrogen. Solutions based on chicken manure should only be used by applying them at the root of the bush. The product contains no toxic substances, it increases the resistance of tomatoes to diseases and accelerates their growth. Dilute 1 liter of water and 1 liter of dry chicken manure, let it brew for 5 days in a warm place. The infusion is stored for a long time, so you can fertilize plants with it throughout the whole season.
2. Boric acid – increases the amount of sugar in plants, protects against parasites and diseases. You can use the root or foliar method. Prepare a solution of 1 liter of water and 1 kg of boron powder. It is better to use hot water, so the powder will dissolve faster. During the fruiting period, use a mixture of boric acid and potassium permanganate.This way you will provide your tomatoes with reliable protection from late blight.
3. Suitable for fertilizing in a greenhouse fresh or dry yeast. Dissolve 100 g of fresh yeast in 10 liters of water and immediately pour the resulting liquid over the tomatoes. For each plant use 0.5 liters of solution. Yeast will not strengthen tomatoes as much as boric acid or chicken manure, but will rather have a general healing effect.
4. Ash is an excellent fertilizer at any stage of tomato growing. During the fruiting period, a solution based on wood ash is especially actively used. To do this, dissolve 1 cup of ash in 10 liters of water and add liquid soap to the mixture. The solution is sprayed onto the bushes from a spray bottle.
5. Young nettle leaves serve as excellent feeding. The container is filled 75% with nettles and water is poured in, after which it is infused in a dark place for 10 days. No more than two feedings are carried out per month.
6. Eggshell good for both young shoots and mature bushes. Soak the crushed shells in warm water and let it brew for 3 days. As soon as an unpleasant odor appears, water the beds with the solution.

Useful tips

Farmers and summer residents advise:

• if the first cluster has large fruits, and the others are undeveloped and small, then immediately remove the tomatoes from the first cluster and generously water the beds with ash solution. In a short time, vegetables are formed on the lower hands;
• if yellow or white spots appear on the leaves, treat the bushes with a garlic solution. Most likely, the plant becomes infected with a fungus;
• if the leaf becomes rough and dull, eliminate superphosphate from the fertilizing and increase the dose of potassium and nitrogen;
• Before applying fertilizer, it is recommended to water and loosen the beds;
• When using toxic fertilizers, follow safety rules. At home, such drugs are stored out of the reach of children.

Reviews

Here's what experienced summer residents say about greenhouse fertilizers:

Maria, Kislovodsk: “I always carefully monitor the appearance of tomatoes, paying attention to changes in the color or shape of the leaves. I use ash solution to prevent various diseases. This is my favorite effective remedy, it makes the harvest tasty and protects against pests. I don’t really trust chemicals; I prefer to use only organics.”

Alexander, Moscow: “In my opinion, there is nothing better than mullein and manure; they nourish the plant and are absolutely safe. I apply such fertilizing both at the seedling stage and at the fruiting stage. Every year is fruitful."

Elena, Saratov: “When caring for bushes, I actively use various fertilizers: both natural and chemical. I especially like “Rastvorin” and “Kornevin”. They are very easy to use and inexpensive. You can buy them at any gardening store.”

Conclusion

It is always important to care for tomatoes in the garden. It doesn’t matter whether they are planted in a greenhouse, greenhouse or open air. The first signs that the plant does not have enough fertilizer are external changes in the bush. First, find out what exactly tomatoes lack, and only then act.

A variety of organic and mineral fertilizers allows you to quickly give the bushes everything they need. Remember that it is better to alternate root feeding with foliar feeding.
