How and what to feed tomatoes during flowering and fruit setting to obtain a rich harvest of large tomatoes

Growing a crop of tomatoes so that the neighbors envy is the dream of every gardener. At the same time, everyone has a natural question about how to feed tomatoes during flowering and fruit setting.

We will tell you what to do to make tomatoes bloom and bear fruit actively, how to care for the plant and what fertilizers to apply for a good ovary.

When and what to feed tomatoes

To better set fruits, tomatoes need nitrogen, potash and phosphorus fertilizers.

Consider the stages of feeding:

1. During soil preparation. For 1 sq. m of land make 8 kg of compost or humus.
2. After planting seedlings. Use nitrogen nutrition: 1 tbsp. spoon of urea, 2 tbsp. tablespoons of superphosphate and potassium chloride. Fertilizer is applied per 1 sq. m beds. Feeding with nitrogen is stopped at the beginning of flowering.
3. During flowering, ovary formation and fruiting. They use potassium-phosphorus nutrition, iodine, boron.

Important! Tomatoes are fertilized every two weeks throughout the season.

What is it for

Tomatoes grow well in fertile soils. Fasting negatively affects growth and fruiting.

Factors to watch out for:

1. The lower leaves and stem turn purple - there is not enough phosphorus. The bushes do not develop, the root system weakens, the fruits lose their taste. Phosphorus nutrition is introduced. Organic fertilizers are suitable for this: bird droppings, mullein, wood ash. The solution is prepared from the calculation: a bucket of water, a glass of ash, a glass of droppings. Fertilizer "plays" for 2-3 days. Then it is diluted with water in the proportion of 1 liter of the mixture to 10 liters of water. Watered with 1 liter at the root.
2. Leaves curl, brown-yellow spots appear - lack of potassium. Fruits stop growing, get sick with top rot. Mineral fertilizers are applied. For 1 sq. m prepare a mixture: 25 g of superphosphate, 5 g of urea, 10 g of potassium salt.
3. Light green leaves - lack of nitrogen, plants are stunted. They are fed with urea: dissolve 1 teaspoon of urea in a bucket of water, pour 0.5 liters under a bush.
4. Few ovaries on tomatoes. They use growth stimulants: "Ovary", "Signor Tomato".

Top dressing scheme

Consider in what periods it is better to feed:

1. Two weeks after planting the seeds.
2. After diving.
3. After two weeks, root feeding is carried out.
4. On the 14th day after disembarking the seedlings.
5. During flowering.
6. When the fruits ripen.

Important! During flowering, nitrogen fertilizers are not used.

Auspicious days

Thinking about how and what to feed tomatoes during the period of fruit ovary, you need to take into account the influence of the Moon on the development of plants.

With the waning phase of the moon, the root system grows. Seedlings planted on such days are quickly accepted. During the growing phase, the upper part of the tomatoes is actively developing.

If you apply fertilizers on the days of the waning moon, a strong bush with developed roots will grow, and if during the growing period, this will help the formation of a large number of ovaries and fruits.

In the open field

Caring for tomatoes and fertilizing in open ground depends on the following factors:

• weather;
• soil condition.

For example, chernozem requires less fertilization than loamy and sandy soils. Fertilization proportions on loamy and sandy soils: for 1 sq. m scatter 40 g of superphosphate, 15 g of potassium salt, 10 g of urea. Add 10 kg of compost or humus. On chernozem soils, the proportions are reduced.

Low temperatures and rainy weather cause a deficiency of nitrogen, so at this time tomatoes are fed with nitrogen fertilizers.

In the greenhouse

The specifics of growing tomatoes in a greenhouse and in an open field are largely similar.

Work begins with soil preparation. In early spring, before digging, fertilizers are applied: 10 kg of compost are mixed with 1 teaspoon of ammonium nitrate, 15 g of potassium chloride and 40 g of superphosphate. The proportion is calculated for 1 sq. m of land.

Features of caring for tomatoes in a greenhouse:

1. After diving, seedlings are not fertilized. Strengthen the immune system by spraying Epin on the leaves.
2. Greenhouse tomatoes need more potash fertilizers. Lack of potassium causes the leaves to wilt.
3. When flowering and forming ovaries, it is important to observe the watering regime. To prevent diseases from developing in the greenhouse, the humidity should be no higher than 75%.

Top dressing is carried out in stages:

1. On the 14th day after planting the seedlings, mineral fertilizers are applied.
2. During flowering, fertilized with potash fertilizers, bird droppings, mullein.
3. If the plants are very stretched, superphosphate is used.
4. When tomatoes bloom in a greenhouse, they are fed with calcium nitrate.
5. To form the ovaries, a mixture is used: a glass of ash, 1 teaspoon of boric acid, a bucket of water.
6. During fruiting, a solution is made: a bucket of water, 2 tbsp. tablespoons of superphosphate, 1 tbsp. spoon of sodium humate.

Important! In the greenhouse, fertilizers are applied every two weeks, in the open field - once every 10 days.

How to water tomatoes

A good harvest can be grown using mineral and organic fertilizers. In doing so, consider the following:

1. For growth, tomatoes need nitrogen fertilizers: ammonium nitrate, ammonia, urea, yeast feeding.
2. When forming ovaries, fertilizers with potassium, boron, manganese, iodine are needed. These are phosphorus-potassium fertilizers: superphosphate, potassium sulfate, boric acid, wood ash.

Boric acid

Boron is essential for the formation of ovaries and the formation of fruits.Boric acid compensates for the need of tomatoes in boron. This is a safe remedy.

Top dressing is carried out in two ways:

1. Foliar method. Spray every week during flowering. Solution preparation: Dissolve 10 g of boric acid in a glass of hot water, then add a bucket of water.
2. Root dressing. Applied during flowering and ovary formation. Watered once every two weeks, 1 liter under a bush. The solution is prepared from a proportion of 5 g of acid per 10 l of water.

Yeast feeding

Sometimes, during the flowering of tomatoes, the ovaries begin to dry up, and inexperienced gardeners do not know what to do and how to feed the plants.Yeast saturated with iron, amino acids, micro and macro elements. They contain fungi that affect the growth and development of tomatoes, and also fight disease.

Dry or fresh yeast is used to prepare the solution:

1. Dry yeast recipe.In a deep bowl, dilute 100 g of dry yeast in 3 liters of warm water, add 50 g of sugar. They put them in a warm place and let them wander for a day. The resulting mixture is diluted in 10 liters of water, poured under a bush of 0.5 liters.
2. Fresh yeast recipe.0.5 kg of fresh yeast and 0.5 l of old jam are mixed in 5 l of warm water. The mixture should wander for a day in a warm place. Then 1 liter of the mixture is diluted in a bucket of water.

Important! The plants are watered abundantly before fertilizing.

Yeast feeding is used no more than three times per season. The procedure is carried out with an interval of 2-3 weeks.

Herbal infusion

A remedy that can be prepared at home. The cut grass is placed in a barrel, poured with water, left for a week to ferment. Add a liter can of wood ash.

Important! To speed up the fermentation process, yeast or whey is added to the mixture.

When a strong pungent odor appears, the fertilizer is ready. Use 1 liter of fertilizer per bucket of water, pouring 1 liter under the bush.

Ash

Fills the need for potassium, phosphorus, calcium in tomatoes.

Ash is used 2-3 times over the summer:

• in the spring for digging the soil at the rate of 80 g per 1 sq. m;
• in mid-July - 0.5 cups per 1 sq. m.

Ash used as a separate fertilizer or included in others. It is scattered under the root before watering or dissolved in water. Use 1 glass per 10 L of water.

Important! Ash is not used when soaking seeds.

Chicken droppings

How can you feed tomatoes so that there are more ovaries? A long-used remedy is chicken droppings. It is an environmentally friendly fertilizer. It contains a large amount of potassium, phosphorus, magnesium, as well as boron, zinc, copper.

Litter is used in two ways:

1. Dry chicken droppings are scattered before harvesting in autumn or early spring. For 1 sq. m of land use 1 kg of dry manure and a glass of ash.
2. Liquid top dressing. Prepared from rotted manure: 0.5 kg of manure per 10 liters of water. Insist for three days.

Important! The solution is poured between the rows.

Fertilizer is applied 2-3 times per season. It is important not to overdo it when using this remedy. Excessive fertilization can lead to increased green mass growth.

Iodine and dairy products

In order for tomatoes to set fruit, it is important to feed them with iodine, potassium, iron, which are found in dairy products. Lactic acids also actively fight against fungal diseases of tomatoes.

Iodine at the same time saturates the tomatoes with the necessary nutrients and works as an antiseptic.

To prepare the solution, use fresh milk, whey or yogurt.

For the prevention of diseases, tomatoes are processed immediately after rooting. seedlings... In the future, spray every two weeks with a solution: 1 liter of milk, 15 drops of iodine, a bucket of water.

Important! The product is used immediately after preparation so that iodine does not evaporate.

Humates

These natural growth promoters are used to increase fruiting.

Properties of humates:

• improve soil structure;
• saturate with oxygen;
• improve the process of rooting seedlings;
• increase seed germination.

Top dressing is carried out every two weeks. Use potassium and sodium humate. 1 teaspoon of powder is dissolved in a bucket of warm water. Water at the root of 0.5 liters three times per season.

Important! Humates should not be mixed with phosphorus fertilizers and calcium nitrate.

Ready-made store preparations

There is a wide variety of off-the-shelf products.

Prerequisites for their use:

1. The bushes are strongly stretched upwards - a superphosphate solution is used: 4 g per 1 liter of water.
2. Plants grow slowly - they use the growth stimulator "Energen".
3. During flowering, apply "Signor Tomato", "Solution", "Effecton".

Mineral fertilizers

The use of mineral fertilizers when growing tomatoes gives good results.

There are three types of such fertilizers:

1. Phosphate fertilizers are used to strengthen the root system: superphosphate, phosphoric flour.
2. Nitrogen ones stimulate the growth of green mass, increase flowering, improve taste: ammonium nitrate, ammonium sulfate, ammonium sulfate, urea.
3. Potash ones increase immunity, improve taste. Potassium sulfate is used in the spring, potassium chloride in the fall. It is necessary to use drugs in moderate doses so as not to damage the root system of plants.

Important! When applying nitrogen fertilizers, lime is added to the soil, since ammonia fertilizers acidify it.

Organic fertilizers

Organic fertilizers, environmentally friendly and safe for humans, will help to increase the number of ovaries. These include compost, mullein, herbal tincture, bird droppings.

The following recipes are among the most effective:

1. Herb tincture with mullein and ash.5 kg of chopped grass are placed in a barrel with water, 2 liters of mullein, 1 glass of ash are added. Insist for two weeks, dilute 1 liter of infusion in 10 liters of water. Watered with 1 liter under the bush. The procedure is repeated every two weeks.
2. Banana skins tincture.The product stimulates the growth of fruits. Place 1 kg of skins in a bucket of water, leave for three days. Dilute with water in a ratio of 1 liter of tincture to 2 liters of water. Before use, add 1 g of copper sulfate to the solution.

How to water

The need for watering tomatoes during flowering and fruiting is different.

During flowering

During this period, ovaries are formed and future fruits are laid.

Water the tomatoes regularly and abundantly during the flowering period.... The watering mode is selected depending on the weather. When it's hot, water it twice a week. In cool weather, once is enough.

During fruiting

Watering during this period, decrease. It is carried out as needed. Watering too much can damage the fruit: it will crack and rot.

In hot weather, one abundant watering every 7-10 days is enough.

Tips from experienced summer residents

How to feed tomatoes for fruit ovary in a greenhouse - know experienced gardeners. What to do when tomatoes are blooming but not set?

Use the recommendations of experts:

1. Use foliar and root dressings throughout the growing season.
2. Apply nitrogen fertilizer only at the beginning of the season to grow a large and strong bush.
3. During flowering and fruiting, use phosphorus-potassium nutrition.
4. It is better to apply top dressing in the evening so that the leaves do not get sunburn.
5. Use hydrogen peroxide in rainy weather. This will improve the structure of the soil, enrich it with oxygen. Plants will better endure bad weather, the ovaries will not fall off.
6. Spray boric acid solution to form ovaries.

Reviews

How to grow a rich harvest of tomatoes and how to feed them so that there are more ovaries - say gardeners with experience.

Valentina, Voronezh: “I have been growing tomatoes for a long time. When I see the problem that the tomatoes are blooming, but there are no ovaries, I spray it with boric acid. I make a solution - 1 teaspoon of acid in 3 liters of water - and spray every week. 2-3 times is enough for the fruit to start to set. "

Ivan, Moscow: “I give preference to organic feeding. It is safe for health. Preparing a tincture of herbs from weeds. I feed it once every 14 days. I add 1 liter of tincture to a bucket of water, a glass of ash, 1 tbsp. spoon of superphosphate ".

Inna, Tomsk: “When neighbors see my tomatoes in bloom, they have a question: how do I feed them? The secret is simple. I use nitrogen fertilizers at the beginning of growth. During the flowering period, I add phosphorus and potash. First of all, I use yeast feeding, alternating it with ammonium nitrate or ammonia. 1 tbsp. a spoonful of saltpeter in a bucket of water is enough for the bush to gain strength for fruiting. I apply fertilizer every two weeks. Then I switch to boric acid, superphosphate, potassium nitrate. "
