How to feed zucchini - we will help you determine the best fertilizer

Fertilizing zucchini is beneficial in cases where the soil is depleted due to regular planting of vegetable crops. There are plants that can extract a large amount of useful microelements from the soil in one year.

Despite the fact that zucchini is not particularly demanding in terms of care, feeding will help increase the yield. At the same time, the fruits will differ in taste, since the application of fertilizers will help improve them.

Feeding zucchini in open ground

Zucchini requires large amounts of nutrients to grow and bear fruit. Fertilizers applied in the fall are not enough for the entire growing season. Fertilizing is required 3 times. The procedures are distributed according to the stage of plant development and are related to its needs at each phase.

First fertilizing after planting in the ground

Zucchini is grown in open ground by seedlings and seeds. Young seedlings are fertilized after 2-4 true leaves appear. The seedlings will need additional nutrients 7-10 days after being transferred to the beds. How to feed seedlings after planting in the ground? At the first stage of development, seedlings and seedlings will require a full range of mineral elements. The main substances involved in the metabolic processes of vegetables are:

• Phosphorus – participates in the synthesis of carbohydrates, promotes the development of the root system. The element is necessary throughout the growing season, especially before flowering. Added with superphosphates.
• Nitrogen is indispensable in the formation of proteins and chlorophyll. Apply in spring and June. The main sources are manure, urea, ammonium nitrate.
• Potassium – helps absorb carbon dioxide and participates in protein synthesis. The element is necessary for the formation of flowers and ovaries. It enters the soil with potassium sulfate and potassium chloride.

Attention. It takes a week for seedlings to adapt to a new location. Fertilizing applied earlier than this period will not be absorbed by the root system that has not taken root.

Young plants are responsive to growth stimulants and organic fertilizers. Recommended for use:

• “Biohumus” is a liquid nutrient composition with minerals, enzymes, and growth hormones. It improves soil health and strengthens plant immunity.
• "Agrkola" - water-soluble granules of universal fertilizer contain a balanced complex of chemical elements for the development of vegetables.
• "Rossa" - liquid fertilizer contains mineral elements and humic substances. You will need 2 tbsp. spoons into a bucket of water.
• Folk remedies are also suitable for the first feeding. Mullein infusion is diluted at the rate of 1 kg per 10 liters of water. 1-2 liters of the composition are poured onto the bush.

How to properly fertilize:

• Fertilizer is used after watering.
• The drugs are diluted according to the instructions, without exceeding the dosage.
• The evening time is selected for depositing funds.
• Fertilizing is done at the root, without getting on the leaves.

What is the best way to fertilize before flowering?

During the flowering phase, the plant spends a lot of energy on forming buds. To reduce the amount of barren flowers and ensure fruit growth, fertilizers are applied a second time. What kind of feeding do zucchini like before flowering? At the budding stage, the maximum amount of potassium and phosphorus is required. The optimal ratio of nutritional components is selected in the “Bud” preparation. It stimulates the formation of flowers and ovaries.

Organic fertilizer "Effecton" is close in composition to manure. Its advantage is the absence of harmful microorganisms found in natural organic matter. The drug saturates the soil with micronutrients. You will need 20 g of concentrate per 10 liters of water. Complete feeding is provided by the introduction of herbal infusion. The cut grass is filled with water and kept for 2 weeks. The green mass is diluted with water 1:10, and each bush is watered with 2 liters. During flowering, fertilizing with ash is effective. The product is rich in potassium and rare trace elements. Their wood ash is prepared as a separate infusion or added to the herbal mixture.

Feeding and care during fruiting

Inexperienced gardeners are advised whether it is necessary to feed the crop at the fruiting stage? As the crop begins to ripen, the crop requires abundant nutrition. It takes all available reserves from the soil. When the growth rate of pumpkin bushes slows down, you should feed:

• “Nitrophoska” is a complex fertilizer that increases yields by 50-70%. Take 30 g per bucket of water, consumption per plant is 1 liter.
• A complex of microelements will provide the following combination: 1 tbsp. a spoonful of superphosphates, ammonium nitrate and potassium fertilizer. The components are diluted in 10 liters of water.
• Don't forget about wood ash. It is diluted in 30 g per bucket of water and applied at the root.

Farmers know how to feed zucchini during flowering and fruiting. Folk remedies perfectly stimulate the growth of culture. Among the drugs that help increase the yield in the garden beds are boric acid, ammonia, iodine and yeast.

Information. Frequent harvesting of pumpkins activates the formation of new fruits.

Tips from an experienced gardener can be found in the informational video at the end of the article.

Foliar feeding

During the period of flowering and ovary formation, it is recommended to perform 1-2 foliar feedings. Nutrient compositions are quickly absorbed by leaves and stems; the procedure is recommended on heavy clay soils. What to use:

• “Biohumus” is a liquid preparation diluted in a proportion of 5 ml per 4 liters of water. Can be used every 7-10 days.
• “Bud” - a growth stimulator that promotes the formation of flowers and fruits, recommended for use in bad weather. Consumption 20 g per 10 liters of water.
• Urea - 7-8 g of the substance is diluted in 5 liters of water, used during the fruiting period.

The procedure is performed in the evening; a household spray bottle is suitable for spraying.

Autumn soil preparation for planting

In order for zucchini to grow well, develop and produce a generous harvest, they need to create the right conditions. This heat-loving garden crop loves well-lit, sunny places, protected from wind and drafts: even with partial shading, fruiting is greatly delayed. In addition, plants love rich, nutritious, well-cultivated soils, so beds for zucchini begin to be prepared in advance, ideally in the fall.

The best predecessors for them are garlic, onions, early cabbage, beans, and peas. A less desirable choice is beds where vegetables of the nightshade family, as well as carrots, were previously planted. And it is not at all recommended to grow plants after vegetables that belong to the same family - cucumbers and pumpkins. All these crops remove the same elements from the soil, which leads to rapid depletion of the soil. Zucchini is returned to its original place after at least 3-5 years have passed.

Preparation of the bed begins with removing weeds and, if necessary, liming. It is carried out on acidic soils 1-2 weeks before applying basic fertilizers and digging. Next, 4-7 kg of organic matter is added per 1 m2 of land. Manure, humus, and compost are used. On heavy clay soils, sawdust and sand are added. In sandy areas there is fertile soil + peat.

Ash (up to 0.2 kg per 1 m2) or superphosphate (at a dosage of 40-50 g) and potassium sulfate (at a dosage of 20-30 g) are used as phosphorus-potassium fertilizers. If there is not enough organic matter, you can additionally use urea (15-20 g). They are scattered evenly over the area, and then it is dug up deeply. In spring, the area is only leveled with a rake.

On sandy soils, where nutrients are quickly washed into deeper layers, it is more effective to apply mineral supplements in the spring at planting or shortly before.

Fertilizer for zucchini

Pumpkin crop is demanding in terms of nutrition throughout the entire growing season. During flowering and fruiting, the need for mineral and organic substances increases several times. How to fertilize zucchini for a good harvest? Vegetables are responsive to fertilizing, which is applied 3 times during cultivation.

Optimal conditions for crop growth are created even before planting. Soil preparation begins in autumn. Manure and compost are placed in the ground, which by spring has time to decompose and enrich the soil with useful components. What fertilizers to apply when planting depends on the type of soil:

1. Sandy and sandy loam soil is poor in nutrients; 4 kg of humus or compost, 50 g of wood ash and superphosphates per square meter are added to it. m. Such soil contains little magnesium; its deficiency is replenished with magnesium oxide or sulfate 3 g/sq.m.
2. Peat bogs require 2 kg of compost, 50 g of ash, 1 teaspoon each of superphosphate and potassium sulfate. It is recommended to use ready-made fertilizers "Agricola-5", "Rossa". The preparations are complex mineral fertilizers. They do not contain chlorine, and the amount of microelements is specially selected for melons. Agricola-5 contains: nitrogen (13%), phosphorus (20%), potassium (20%), boron, copper, zinc and magnesium.
3. Clay soil and loams need to improve the soil structure. Before planting, add 2-3 kg of peat, sawdust and humus. Ash and superphosphates – 25-30 g per square meter. m. You can use liquid potassium humate. Fertilizer is a plant growth stimulator, improves the absorption of beneficial elements by the root system, and strengthens the immune system.

Information. In zucchini, the root system diverges over a considerable distance, so it is recommended to apply fertilizer to the garden bed, and not to individual holes.

Many gardeners create warm beds and add compost to their base. Organic plant debris makes an excellent fertilizer and warms the soil as it decomposes.

Stages of seasonal fertilization

Depending on the goals and timing, several stages can be distinguished when feeding zucchini is applied.

Spring feeding

In the fall, the soil is dug up. In the spring, the procedure is repeated, weeds are removed and humus or compost is added. Do not use fresh manure as it can burn the roots of the plant. For 1 m2 of land you will need up to 3 kg of organic matter. To this add 20 g of nitrophoska and 2 tbsp. l. potassium

First feeding

It is carried out when young shoots appear approximately 10 days after seed germination. The goal is to strengthen the roots and stimulate growth. Nitrogen is used in the form of organic matter and mineral fertilizers. Dosage is 2 times less than indicated in the instructions for adult crops.

After landing in the ground

7 days after planting in a permanent place, you need to decide how to feed the zucchini for growth in open ground. During this period, it is recommended to use inorganic substances with a predominance of nitrogen in the composition, which helps the plant grow green mass.

When flowering

In June or July (depending on the region), when inflorescences appear, potassium fertilizers are used. You can use ready-made mixtures or prepare an infusion with the addition of ash.

After flowering

Fertilizer for zucchini must contain an NPK complex. Mineral mixtures are already formulated in the required proportions, so it is more convenient to use ready-made formulations.

During fruiting

During this period, you should carefully choose what to fertilize zucchini for a good harvest, in order to avoid the accumulation of nitrates in vegetables. It is better to choose formulations without nitrogen or with minimal nitrogen content. Potassium preparations, superphosphate, and urea are used. The purpose of feeding is to improve the size and taste, quality and keeping quality of products.

What to water with

Plant feeding begins after the appearance of 2 true leaves. Regardless of where the crop is grown in pots, seedlings or open ground. To ensure that the substances are well absorbed by the plant and do not cause burns to the roots, they are dissolved in a large amount of water. The crop needs mineral and organic substances; they are added in the form of a solution, combined with watering. How do experienced gardeners fertilize zucchini for a good harvest?

Iodine

Feeding zucchini with iodine helps maintain plant immunity and improves fruit development. In micronutrient-rich soil, the leaves are always green and the flowers bloom profusely. You will need 40 drops of pharmaceutical preparation per 10 liters of water. To prevent fruit rot, pumpkin crops are watered with iodine solution 2 weeks after planting. The second time the drug is applied during flowering.

Ammonia

Ammonia is a chemical compound of nitrogen and hydrogen and is used to make fertilizers. In the growth phase, ammonia promotes a rapid increase in green mass. The nitrogen contained in it is easily absorbed by plants. When using ammonia for zucchini, precautions should be taken. Before breeding, you must wear rubber gloves. It is better to perform the procedure outdoors rather than indoors.

Attention. The use of the drug in the recommended dosage is beneficial; excess nitrogen provokes the occurrence of diseases.

Feeding zucchini with ammonia helps to avoid many problems:

• Yellowing and drying of leaves in the lower part of the bush.
• Fragility of stems.
• Insufficient amount of ovary.

The drug is diluted in the proportion of 3 tbsp. spoons into a bucket of water. It is used for seedlings and adult plants.

Folk remedies and methods of feeding them

To improve the structural characteristics of the soil and increase the yield, experienced gardeners alternate the application of complex mineral fertilizers, organic matter and folk remedies. The latter, due to the fact that they are always at hand, for this reason can be used quite often, let us consider in more detail.

Ash

A natural fertilizer that contains almost all the nutrients that zucchini needs, with the exception of nitrogen. If manure was added to the garden bed in the fall, enriching the soil with nitrogen, the ash can be used as the only fertilizer.

Ash successfully reduces soil acidity levels. 1 kg of wood ash is equal in effectiveness to superphosphate or lime, which are also often used as deoxidizers.

Ash is introduced into the soil in the following ways:

1. In dry, granular form, according to the scheme: 2 tbsp. spoons into the hole during planting, 0.5 kg per m² in the fall for digging.
2. An aqueous solution – 2 large glasses per 10 liters of water.

You can soak the seeds in an ash solution (2 tablespoons per 1 liter of water) before planting.

Important! Only wood ash is suitable for fertilizing plants.

Yeast

Yeasts secrete unique substances that are beneficial for all plants. Zucchini, for example, responds to them with active root growth, and as a result, a rich harvest.

Yeast, like ash, can be added dry or in an aqueous solution. The second method, according to reviews, is more effective, but you shouldn’t dismiss the first one either.

Remember! Yeast can only grow in warm conditions. For this reason, yeast feeding should be carried out exclusively in warm weather.

Solutions options:

• With live yeast . Dissolve 100-120 g of yeast in a liter of warm water. Leave for 1-2 hours. Afterwards, add it to a container of water. Water immediately.
• With dry, granulated yeast . Pour a small packet of yeast (10 g) into 10 liters of water at room temperature, add 4-5 tbsp. spoons of sugar, mix. Leave for 2 hours in a warm, sunny place and you can water.

An alternative to fermentation yeast can be crackers, dry bread crusts, and old jam. With these ingredients, the fertilizing will take a little longer to prepare, about 5-7 days, but will not lose its effectiveness.

Herbal infusion

Also, like the previous ones, it is used for feeding vegetables. The main advantages of fertilizer are ease of preparation and lack of financial costs for purchase. Herbal infusion is usually prepared in large quantities at once. The ideal capacity is a 100-150 liter barrel. Fill it halfway with fresh herbs, top up with water and leave until fermentation occurs.

In the summer, in the heat, fermentation occurs quite actively, especially at first. The liquid begins to bubble and even foam, and after a couple of weeks the solution will be ready for use. It is possible to speed up the process if you add a jar of jam or some crackers to the infusion. The finished infusion becomes transparent. The infused liquid is diluted with water in a ratio of 1:2. You can also add 1 large glass of ash per 10 liters of solution.

The herbal infusion usually contains mowed lawn grass or weeds from the garden, collected after weeding, but the best infusion is made from nettles and legume stems. If possible, it is better to use them.

Iodine

The value of iodine for zucchini is that the substance can be used not only as a top dressing. Iodine is an excellent preventative against rot. Also, the substance helps strengthen the immunity of garden plants and has a positive effect on the development of fruits.

The water solution for irrigation is prepared in a couple of minutes. Add 40 drops of iodine into a bucket of lukewarm water and mix. Use immediately. The first watering of zucchini is carried out 14 days after planting, the second - during flowering.

Ammonia

Ammonia, a compound of nitrogen and hydrogen, is essentially an excellent fertilizer for plants that need these substances. Fertilizing with ammonia leads to rapid growth of leaves and greenery.

Watering zucchini with an aqueous solution of ammonia will help avoid such common problems as:

• drying of the lower leaves;
• stem fragility;
• poor formation of ovaries.

Preparation of the solution: add 3 tbsp to a bucket of water. spoons of ammonia, mix thoroughly. Use immediately.

Boric acid

Boron has a positive effect on plants during the flowering period. Like the previous solutions, the boron solution is prepared in a couple of minutes and costs practically nothing in terms of financial costs.

The spraying solution is prepared in the proportion of 1 g of substance per 1 liter of water. Stir until the boron is completely dissolved.

In rainy and damp weather, spraying is not carried out, because the solution will instantly be washed off the leaves and will not bring any benefit. Also, spraying should not be carried out on a sunny day so that the plants do not get burned. The ideal time for the procedure is morning or evening, before sunset, after the midday heat has subsided.

Boron treatment can be carried out repeatedly. Once a week, throughout the entire flowering period. Experienced gardeners note the positive effect of spraying with boron on the taste and quality of fruits, due to an increase in vitamin C and carotene in zucchini.

To summarize, there are a lot of options for feeding this valuable vegetable. With due diligence, even a novice gardener will have a good harvest. The main thing is to fertilize on time.

Do zucchini like manure?

Organic matter is the best fertilizer for melons; when growing them in compost or manure beds, you can do without additional fertilizing. Manure contains much more chemical elements than any complex mineral fertilizer. In addition, they are in an easily digestible chelated form. To fertilize the garden, use horse, cow, sheep or rabbit manure. It contains microorganisms that form humus. The release of carbon dioxide during decomposition stimulates photosynthesis and contributes to the heating of the earth. Manure has an alkaline reaction; when added, the acidity is neutralized.

Advice. Fresh manure can only be used for feeding, diluting it with water. Use fertilizer in the recommended proportion; its excess will worsen the shelf life of vegetables.

Completely rotted dry manure is called humus. It can be added to the ground in the spring or used as mulch. Humus contains less nutrients than manure, but it does not burn the plants.

Transplanting

In regions with cool climates, zucchini is grown from seedlings. She is planted in an open area after a month. A guideline could be 4-6 leaves on a bush.

The holes are placed at a distance of 60 cm from each other, in a checkerboard pattern. This planting scheme promotes better ventilation of seedlings, fruits and soil:

• For zucchini, fertilizing is introduced already at planting. Use complex fertilizer “Nitrophoska”. For 1 hole 5 g, granules are mixed with soil. It should be damp. The bottom is dusted with ash;
• you can introduce calcium nitrate, 5 g;
• add vermicompost and sapropel, 20 g each. Organic matter is usually chosen for improving the garden bed;
• when introducing mineral fertilizers, succinic acid is used; crush 1 tablet

After planting the seedlings, local watering is carried out. Water can also be used before planting seedlings in the ground.

What to feed during flowering

The period of budding and flowering lays the foundation for a rich harvest. To ensure that the plant receives all the necessary nutrients, root and foliar feeding is carried out. A deficiency of necessary elements leads to various problems:

• female flowers do not set;
• there are a lot of barren flowers on the bushes;
• small pumpkins become deformed;
• the ovary rots.

It is important to choose the right fertilizer, otherwise the plant will begin to grow green mass, to the detriment of flowering. You should choose formulations with a reduced nitrogen content, and the amount of phosphorus and potassium should be increased. The following recipes are recommended:

• Take 2 cups of ash, dissolve in 10 liters of water and leave for 2 days. Water at the root.
• Dilute chicken manure in warm water at a rate of 1:20, fertilize after rain or irrigation. For each bush, 1 liter of solution is used. The litter can be replaced with mullein 1:10.
• The drug "Effecton" is a biologically active fertilizer based on compost. Contains useful enzymes that improve the process of photosynthesis. For root feeding you will need 200 g per 10 liters of water. When spraying leaves, it is enough to dissolve 20-30 g in a bucket of water.
• Mix 40 g of superphosphates and 35 g of potassium nitrate, dilute in 10 liters of water. Use after watering; this volume is enough for 6-8 plants.
• Nettle infusion is another option than watering zucchini for intensive flowering. You can use any herb, but nettle composition is considered the most useful. Plants are infused in a container with water for 7-10 days. Before adding, the fermented composition is diluted with warm water 1:10.

During the flowering period, gardeners advise foliar feeding with Nitroammophoska. Granules containing all essential minerals are dissolved in warm water (10 g per 5 l). Treatment is carried out in the evening so that the composition is absorbed by the plant and does not evaporate.

Development of leaves and stems

To ensure that seedlings gain green mass well, nitrates are used. Plants require nitrogen fertilizers throughout the growing season. For the development of leaves and stems, it is better to use mineral complexes:

Fertilizers are diluted according to the instructions. Up to 1 liter of liquid is injected under each bush. The solution is injected along the rim of the hole. It is undesirable for the liquid to come into contact with the stem. For zucchini, foliar feeding is always carried out.

As a nitrogen fertilizer, use a solution of mullein 1:3 or a solution of bird droppings 1:10. It's organic. It is difficult and time-consuming for seedlings to assimilate. It is better to replace it with urea. One plant requires 2 g/l.

Feeding zucchini with yeast

Experienced farmers know about the benefits of baker's yeast for garden and vegetable crops. They stimulate the development of roots and above-ground parts of plants. Yeasts serve as catalysts for the decomposition of organic matter in the soil and create a favorable environment for the growth of microflora. The product contains proteins, minerals, vitamins and amino acids. Is it possible to feed zucchini with yeast in open ground? This procedure is beneficial for vegetables. It can be carried out immediately after planting seedlings to improve the survival rate of seedlings.

Dry or pressed baker's yeast is used as fertilizer. Their action is the same, only the methods of preparing the fertilizer differ. Several recipes are offered:

• The yeast briquette is diluted in warm water in a ratio of 1:5. The mixture is infused for 12 hours, then diluted 1:10 and watered the bushes.
• The dry product (10 g) is dissolved in a bucket of warm water, 50 g of sugar is added to speed up the fermentation reaction. After 2 hours the composition is ready for use. Before watering, dilute 1:5.
• 100 g of yeast, 100 g of sugar are placed in a 3 liter jar and filled with warm water. Leave for 1 week. The fermented mixture is used in the amount of 1 glass per bucket of water.

The use of yeast requires compliance with certain conditions:

• Make sure the soil is warm before feeding your zucchini. Yeast does not work in cold soil.
• You should not use yeast mixture often. It increases nitrogen concentration but leads to potassium and calcium deficiency.
• The yeast mixture can be supplemented with bread crumbs, ash, and nettle infusion.

The root system of zucchini, thanks to the action of yeast fungi, grows many lateral processes. They provide the plant with abundant nutrition.

Signs of macro and micronutrient deficiency

The situation when zucchini does not grow, begins to change shape or becomes deformed is familiar to many summer residents. The reason for the changes lies in the balance of plant nutrition. Common fruit defects:

• lines and streaks on the peel indicate a lack of boron;
• fruit rotting can be caused by iodine deficiency;
• lack of potassium leads to the formation of a spherical tip;
• narrowing of the central part of the zucchini means calcium deficiency.

A tapered tip of a lighter shade than the rest of the fruit signals a nitrogen deficiency. It should also be taken into account that zucchini is a light-loving plant. Bushes growing in the shade develop poorly.

Fertilizing zucchini with urea

Almost half of urea consists of nitrogen. This element is basic for the growth and development of any plant. Is it possible to use urea (carbamide) to feed zucchini in open ground? The opinions of farmers are divided; there are supporters and opponents of fertilizer. Pros of urea:

• quickly absorbed by the plant;
• increases crop yield;
• eliminates pests and diseases.

If urea is applied in excess, negative consequences arise: ammonia gas is formed, which damages the plant. Urea is produced in the form of dry granules. Is it possible to water zucchini with urea? A solution prepared according to the instructions, 15 g per 10 liters of water, is used for root feeding. Fertilizer can be applied in the spring in dry form, incorporating it into the soil. Urea combines well with potash fertilizers. Before feeding the plant, pour 50 g of ash into the ground.

Feeding zucchini with ash

Wood ash contains many micro and macroelements in an easily accessible form. This valuable fertilizer is applied dry into the hole when planting seeds or seedlings. Novice gardeners don’t know whether zucchini likes ash? Its application is part of a bountiful harvest. Why fertilizer is useful:

• it improves the soil, helps reduce acidity;
• wood ash is an excellent remedy against pests and plant diseases;
• The composition contains useful elements - phosphorus, potassium, magnesium, sodium.

During the growing season, it is better to feed the plant with an infusion of ash. It’s easy to prepare: 1 cup of the product is dissolved in 10 liters of warm water. After a day, the infusion is ready; before feeding the vegetables, it is thoroughly stirred. The composition is especially effective during the flowering of zucchini. Is it possible to fertilize the soil with ash during fruiting? It’s even necessary; together with compost or chicken manure, it enriches the soil with essential elements. Fertilizers applied during the fruiting stage affect the taste of pumpkins. Wood ash does not impair the taste of the vegetable.

How does fertilizing affect growth and fruiting?

The composition of the soil when growing zucchini is important throughout the growing season. But during flowering and fruit ripening, the need for nutrients increases several times. Growing zucchini needs potassium and phosphorus most of all. Popular additives: “Effecton”, superphosphate. The absence of the necessary elements can lead to the formation of barren flowers; the ovaries will form deformed or may simply rot during the growth stage.

It is better to refrain from nitrogen-containing mixtures, as they provoke active growth of green mass. In addition, excess nitrogen slows down the growing season and the fruits will ripen at a later date.

Treatment of zucchini with boric acid

Boron is an important chemical element for melons and melons. It improves potassium absorption and stimulates protein synthesis. When there is a lack of a microelement, the leaves of plants turn yellow and the number of flowers decreases. Boron strengthens the crop's immunity and increases resistance to drought and cold. How to feed a bush with boric acid? It is necessary to dissolve the substance in hot water (in cold water the process does not work well). For poor soil, 10 g per 10 liters of water is recommended. There is 0.5 liter of solution per plant.

Is it possible to spray the composition on zucchini leaves? Foliar feeding is a common option. To carry it out, a solution of a lower concentration of 1 g per 10 liters of water is prepared. Treatment is carried out in the evening or in the morning so that drops of the composition do not cause a burn on the leaves.

Advice. Before the procedure, check the weather; rain will wash the drug off the leaves.

Boron is beneficial for zucchini fruits, it improves their taste and increases their sugar content.
