Boric acid as a fertilizer for strawberries in spring. Boric acid for plants, application or how to make the product effective!? Action and basic rules of use

Caring for garden strawberries consists of many activities, but in the spring it is important to pay special attention to feeding. To a greater extent, it should contain nitrogen to stimulate the growth of foliage and shoots. Often during this period, yeast, herbal infusions, ash, as well as drugs from the pharmacy: boric acid or even iodine are used to fertilize strawberries. Recipes and recommendations from summer residents in the video will help you prepare solutions of the correct concentration.

Folk remedies for strawberries: yeast, ash, herbal infusions

It is believed that in the first year after rooting there is no need to feed the bushes. After all, the necessary fertilizer is applied immediately before planting. Strawberries need additional nutrition starting from the age of 2 years. And you need to act according to this scheme:

  • in the 2nd and 4th years - the addition of organic matter and minerals;
  • in the 3rd year - only minerals are required.

Since strawberries should be transplanted to a new place every 4-5 years, this scenario can be repeated every time.

When the snow melts and warm weather sets in, you need to plan the first spring feeding of the plant. It usually falls in March-April. Some summer residents use fresh yeast to fertilize strawberries during this period. You can prepare the solution like this:

  • dilute a pack weighing 1 kg in 5 liters of warm water;
  • add 0.5 liters of mixture for each bush.

An alternative to “live” yeast is dry yeast. From these, the solution is prepared as follows:

  • 1 sachet and 2 tbsp. l. sugar is mixed with warm water. You only need a little of it;
  • add this to a bucket of water;
  • stand for 2 hours.

Attention! The yeast mixture saturates garden strawberries with copper, calcium, potassium, phosphorus and other elements, thanks to which the plant develops well.

Another common component of spring feeding is ash. It contains potassium, phosphorus, and other useful substances. Some gardeners pour a handful of dry ash into the rows while mulching the soil. Do this before watering or on the eve of rain.

You can use an ash solution. For this:

  1. Pour 1 liter of hot water into a container containing 1 tbsp. ash.
  2. Leave for 24 hours.
  3. Add water to make 10 liters of solution.
  4. Mix well and pour over the strawberries. For 1 sq. m of planting you will need 1 liter of mixture.

Infusions of various herbs are also popular as supplements. In the spring, for these purposes, you can take young nettle, which enriches garden strawberries with vitamins. 1 bucket of herbs is poured with warm water and left for 3-4 days. Another way is to leave the nettle under pressure for 1-2 weeks. During this time, the mass must be stirred daily. Before use, dilute every 0.5 liter of fermented infusion in a bucket of water.

Recipes for “pharmacy” fertilizers with boric acid and iodine

Since iodine is an antiseptic, it is quite capable of preventing the development of certain diseases on strawberry bushes. Summer residents note the effectiveness of the medicine against various fungi and bacteria. One-time spring feeding should be done after pruning the foliage. The plant is watered with water to which iodine has been added (you need to take 15 drops per bucket). If you add 1 tbsp to the same mixture. homemade serum, you can treat garden strawberry bushes leaf by leaf, i.e. spray.

Attention! When using iodine, strictly follow the proportions.

Fertilizing garden strawberries with boric acid helps increase yield and improve the taste of sweet berries. Such feeding is especially important in cases where the plant itself signals a boron deficiency by showing curved leaves. If you want to do foliar feeding, mix 5 g of boric acid with a bucket of water. In early spring, water the strawberry beds with a solution consisting of:

  • 1 g boric acid;
  • the same amount of potassium permanganate;
  • buckets of water.

This volume is enough for 30-40 bushes of the crop.

Advice. To dissolve boric acid, use hot water, and to bring the mixture to the desired volume, use warm or cool water.

Another recipe for spring feeding suggests mixing 1 tsp in a bucket of water. boric acid, 30 drops of iodine and 1 tbsp. ash. Another option is to add 0.5 tsp to the same amount of liquid. boric acid, 1 tbsp. urea, 3 g of potassium permanganate and 0.5 tbsp. ash. There are many options, but what to use is up to you.

Boric acid for plants, application or how to make the product effective!?

Boric acid for plants, the use of which is quite widespread, is often used by gardeners to feed tomatoes, cucumbers, peppers, garden roses, indoor plants and other garden and vegetable crops. Spraying plants during flowering and not only has a positive effect, but first you need to correctly measure and dilute such fertilizer...

Boric acid for plants - what is the effect of use?

Boric acid for plants, application and benefits - in its chemical composition, in addition to boron, there is oxygen and hydrogen, which are vital for all living things. What is boron useful for? It promotes the formation of chlorophyll, which gives plants a green color, stimulates growth, promotes better rooting of seedlings, participates in the ovary process, and strengthens the plant as a whole.

Spraying plants with boric acid helps restore life to wilted leaves, increases survival in unfavorable conditions and fights infections and pests. Hydrogen peroxide added to the soil reduces the shedding of flower stalks, has a beneficial effect on yields and adds sweetness to the soil. If you are the owner of a wetland with a high acid content, you cannot do without this fertilizer.

Despite the fact that the substance belongs to the class of acids, it is the safest chemical compound that can be used in the garden, it is almost impossible to get burned and it is very difficult to harm the plant, the product does not acidify the soil. However, once it enters the body, it takes a long time to be eliminated. Garden plants are classified into three groups according to the need for fertilizing with boric acid:

  • high degree – for cabbage, apple trees, svela
  • medium – stone fruit trees, carrots, all types of salads
  • low – legumes, herbs, potatoes, strawberries,

Everything is good in moderation - an excess of boron is also undesirable, and an indicator of plant oversaturation will be dome-shaped foliage with dried edges, yellowing of old leaves (if this is not a seasonal need).

A large concentration of the element contained in the grass accumulates in the bodies of animals, which is fraught with the development of various chronic diseases. This raises the question - how to use boric acid powder to fertilize and not harm.

Boric acid for vegetables - how much and when?

Do no harm - not empty words, but practical guidance for any gardener. To benefit plants, it is important to maintain the dosage of boric acid when fertilizing and spraying tomatoes, cucumbers, cabbage, strawberries, roses, indoor and other crops.

Boric acid is used for rapid germination and survival of seeds. A composition is prepared from 5 liters of water and 1 gram of a substance in which the seeds are soaked before planting in the ground - tomatoes, carrots, onions, beets are left for 24 hours, melons, cabbage - up to 12 hours. It is recommended to water the planting holes with the remainder of the mixture.

Spraying strawberries with boric acid will get rid of aphids, ants and other pests, and during flowering it will help increase the number of ovaries; the fertilizer also promotes abundant flowering and increases the amount of sugar in the berries. To combat gray mold and during flowering of strawberries, feed the soil with a composition of 2 g of boric acid, 2 g of potassium permanganate, 15 g of iodine and 1 cup of ash (dilute all components in a bucket of water and let stand for 2.5-3 hours, then spray ). To increase the yield, before flowering begins, it is necessary to fertilize the soil with such a solution - 10 g of acid, 10 g of manganese, 10 liters of water.

A lack of boron affects fruit trees, as a result, the fruits are deformed, become unnaturally dense, and the leaves wrinkle. To replenish the microelement supply, the tree must be sprayed with a 0.2% acid solution. 2-5 liters are consumed per tree, depending on the size of the crown, processing is carried out from the bottom up before and during flowering.

Boric acid for cucumbers is a guarantee of abundant flowering and ovaries; for better results, apply a mixture of 5 g of the substance per 10 liters of water to the root zone before flowering and repeat the treatment, only after spraying the plant’s ovaries, after 5-7 days. The same recipe is suitable for eggplants, peppers and zucchini.

To ensure that new grape seedlings are well accepted in a new place, treat them with 5 grams of peroxide and 10 liters of water; spray the vine with the same composition during bud setting, which will increase the yield by 20%. Chlorotic spots on the foliage are a sign of boron starvation; in early spring and during preparation for winter it will save you from many problems.

Tomatoes need a high boron content throughout the growing season, so spraying tomatoes with boric acid powder improves the absorption of minerals and promotes abundant flowering. If tomatoes germinate in conditions of high humidity, the substance will prevent rotting. When the plant is treated with the composition, the yield increases by 20%, and the taste noticeably improves. It is good to soak tomato seedlings in 2% before planting - the bushes will tolerate transplanting more easily and will grow faster.

Boric acid has proven itself well for indoor plants and garden flowers; a 1% solution (1 g per 1 l) is used for fertilizing; if other elements are added to boron, the concentration is halved. To stimulate budding and flowering, plants are sprayed with a useful composition once every two weeks. Boric acid is very good for orchids - the plant should be sprayed during the release of the arrow and after flowering to stimulate subsequent flowering.

For roses, the mixture is used to prevent fungal infections and aphids, and before planting, it is worth placing the seedlings for a few minutes in a 2% solution. Gladioli and dahlias are fed with 2% product during the appearance of the third or fourth leaves and during flowering. The procedure is performed in the evening once every two to three weeks.

Use of boric acid in the garden

How to dilute boric acid for plants?

  • The substance dissolves exclusively in boiling water; for complete dissolution, the required amount is diluted in a small amount of liquid, then diluted with the required amount of water.
  • To measure 2 g, you need to take the amount on the tip of a knife (you will get a 2% solution per liter of liquid)
  • A teaspoon holds 5 grams of boric acid, a heaping spoon holds 6, and a partial spoon holds 4. Therefore, to measure 1 gram, you need to take ¼ of a partial teaspoon of powder
  • If the fertilizer is planned to be used in combination with other components, the concentrate must be halved

In the garden, fertilizer is used several times per season. To prepare the soil for planting, water the ground with a mixture of 2 g of the drug per 10 liters of water. For 10 sq. m. you will need a bucket of mixture. This treatment will enrich the soil with boron and neutralize it from pests and fungi.

The second treatment occurs during growth, with a 1% composition in the form of foliar feeding. Spraying is carried out at the time of bud formation, flowering and fruit formation, with a mixture of 5 grams of the drug (1 teaspoon) per bucket of water. Irrigation should be done in calm weather in the morning or before sunset. Despite the slight harmfulness of the substance, it is better to protect yourself with rubber gloves, boots and a respirator.

Now you know how to properly use boric acid for plants in the garden and on the windowsill.

Boric acid is often used by summer residents to get the maximum yield of strawberries. In some cases, fertilizing is forced if the plants do not have enough boron. A lack of a microelement can be recognized by yellowing of the edges, dying, curling of leaves (necrosis), as well as the formation of a large number of asymmetrical berries.

With a lack of boron, the root system begins to rot, as a result of which the plant does not receive sufficient nutrients and water from the soil.

Boron is involved in the movement and accumulation of sugars in a number of fruit and berry crops, including strawberries. It promotes better absorption of calcium from the soil by the plant, improves and restores the root system of garden strawberries.

In sandy and sandy loam soils, this important element is washed out of the ground by 85%. When grown in such soil, strawberries will almost certainly need boron.

Boron deficiency most often occurs during rainy seasons. The level of boron in the soil also decreases each time after the liming procedure.

Typical signs of boron starvation:

  • Stopping the development of ovaries.
  • The appearance of necrosis on the shoots.
  • Grinding berries.
  • Noticeable reduction in yield.
  • Uneven ripening of berries.
  • High water content and low sugar content of fruits.

When and how to process?

Boron is well absorbed by strawberries in solid and liquid form. It is advisable to treat garden strawberries with boric acid shortly before flowering, when buds begin to form.

Dissolve 2 g of boric acid in a 10 liter bucket of water. Water at the root on pre-moistened soil. 200 ml of working solution is poured under each bush.

For better dissolution, first dilute the specified amount of acid in a small volume of hot water. Mix the resulting composition with the remaining volume of water at a lower temperature (warm or room temperature).

When foliar feeding, the concentration of boric acid in water is reduced by 4 times, to 0.5 g per 10 liters of water. The first spraying is also carried out during the period of active budding, the second - at the time of flowering, and the third - during fruiting.

This microelement is very well absorbed by strawberries through the leaf blades.

The application of boron can be done in conjunction with fertilizing with other mineral and organic fertilizers.

Processing result:

  • Increase in berry yield by 20%.
  • Increased resistance to disease.
  • Improving the taste of berries, reducing their wateriness. The fruits become sweeter.
  • Formation of more ovaries.
  • Increased resistance to adverse weather conditions (heat, cold snaps, temperature changes).

The decision on what to feed strawberries during flowering is made by the summer resident taking into account the type of soil, the needs of the crop and the approach to cultivation. The addition of mineral and complex compounds solves the problem of shortage of any element, and if handled correctly, does not cause harm to health.


Summer residents successfully regulate the sweetness of the berry and the duration of its storage by applying fertilizers. If the moment is chosen correctly and the dose is correctly calculated, there will be no harm to human and plant health. Fertilizing strawberries during flowering not only improves their taste, but also prevents the appearance of diseases and pests. There are several basic rules in this matter.

  1. You can feed the bushes during the flowering period once with any of the selected recipes.
  2. If you feed the plants with organic matter, it is absolutely safe and the harvest will remain healthy. But measure and proportion remain an important criterion; an excess of fertilizers does not always go unnoticed.
  3. Any fertilizer works at full strength when it gets into moist soil. It is optimal to carry out this procedure after heavy rain or watering.
  4. When watering, you should carefully examine the foliage of the bush for drops of solution. Do not allow liquid solution to accumulate on greens or berries if it has been prepared for watering.

Fertilizing strawberries during flowering with folk remedies

In the home medicine cabinet, in the kitchen and in the garden itself there will always be products that will replace fertilizers from the store and save money. Fertilizing strawberries during flowering is carried out by watering or spraying. To do this, solutions are prepared from yeast, ammonia, and other means that are not related to agrochemicals or fertilizers are used. With the right concentration, their effectiveness is almost the same, and the risk of overdoing is reduced to zero.

The plantings should be fed twice a season to get a large harvest. Suitable for many garden crops; live and dry work equally well.


A lack of boron leads to yellowing of the edges of the foliage, and the greenery gradually begins to curl and die. The berries become asymmetrical and the roots rot. On sandy and sandy loam soils, boron is almost always washed out by 85%. Therefore, for such soils, preparations with boron are indicated during heavy, prolonged rains or after liming the soil. Boron is perfectly absorbed by strawberries in liquid and solid forms.

Boric acid for strawberries during flowering is applied in parallel with other mineral and organic fertilizers. This should be done immediately after the formation of buds begins.


An excellent solution for feeding strawberries during flowering is wood ash. It is a potassium-phosphorus fertilizer containing a large amount of microelements. These elements are important for the formation of fruits and berries, therefore they should be added during the bud opening period. Ash for strawberries during flowering can be added in dry or dissolved form.


Ammonia promotes the growth of green mass and increased productivity. It plays the role of preventing the appearance of insects and diseases. They work with ammonia in three passes: in early spring to prevent pests, during flowering for final protection from insects and the laying of berries, the third time you can feed after harvesting to restore the strength of the bush.

Ammonia for strawberries during flowering is prepared according to the recipe: mix ten liters of water with three tablespoons of ammonia. The dosage for the second application is in such a concentration that it can cause burns to the foliage. If after watering drops of the product are visible on the foliage, you need to re-water with clean water and wash off the residue. This will increase the quality and quantity of the harvest and get rid of remaining insects.


Mullein is actively used by summer residents, because it helps to achieve a plentiful and large harvest. During the flowering period, you can feed according to an effective scheme.


Fertilizing strawberries during flowering with mineral fertilizers

Industrial powders and granules are at the same time assistants to the summer resident, and can become a source of problems if handled incorrectly. The number of applications, their processing time and proper selection are the basic rules for obtaining a high-quality harvest. The lack of one or another element will certainly affect the size of the berries and the condition of the foliage. If they are not in the soil, fertilizing strawberries during the flowering period will save the harvest.

Urea will provide the bushes with a good set of green mass, and this is the key to rapid growth and budding. During the flowering period, it is advisable to feed one leaf at a time. This period lasts about four weeks, and the plants have time to use up the entire volume of nutrients without storing them in reserve in the berries.


Apply in the form of granules directly into the hole if the bushes change their place of growth. The first treatment is done with the appearance of the first greenery, if there has been no replanting. Secondary nitroammophoska for strawberries during flowering is used for all plants. Before the ovaries form, you need to spray or water the plantings. 30 g of the substance are diluted in a ten-liter bucket. To feed the plant, pour in half a liter. For spraying, the concentration can be reduced slightly. This is the answer to the question of what to feed strawberries during flowering in summer or spring.


Potassium helps strawberries more easily withstand high temperatures in the summer. The plant will absorb it from the soil. For calcareous soils, potassium starvation of strawberries is a frequent phenomenon, because the increased content of calcium and magnesium simply displaces potassium. An excess of the element is also bad for strawberries, because then a magnesium deficiency begins. Potassium for strawberries during flowering should come from high-quality fertilizer formulations. Cheap ones contain chlorine, which will negatively affect the harvest.

The optimal formula for safely feeding strawberries during flowering is considered to be the composition. If the bushes have a blue-green coloring of the foliage, and growth is significantly slower, then potassium starvation has begun. A teaspoon of potassium magnesia per bucket of water is enough to obtain a safe composition. Half a liter of the prepared solution is poured under the bush.


This mineral fertilizer is a source of potassium and nitrogen. Potassium nitrate for strawberries during the flowering period is used in the form of a solution for watering or spraying.

When and how to feed strawberries with boric acid and iodine?

Gardeners are very careful about their planted plants in the garden and care for them in every possible way. So they take proper care of the strawberries so that they grow healthy and have a good harvest. It needs to be fertilized more than three times a year. The first time this must be done during planting and its growing season, the second time it must be done during the flowering period, when the blossoming flowers are already visible, the third time it must be fertilized in the autumn, before going under the snow.

Still, there are those who simply planted a plant, ignore it and simply water it, thinking that everything will grow by itself. But they do not take into account the fact that feeding during the flowering process of a plant is a very important stage for them. After all, during the flowering period they require more vitamins and nutrients.

Why is fertilizing carried out precisely during the flowering of the plant?

In fact, the plant requires nutrients all year round. This is especially necessary to do if strawberries have been growing in the same place for more than one year. Since it takes all the nutrients from the soil in the first year, the rest of the time it will have a deficiency of useful components for growth and health, it will develop slowly. Additional fertilizing during flowering is necessary to ensure good formation of stems, ovaries and inflorescences, because the quality of the resulting harvest will depend on this. The purpose of artificial feeding with additional fertilizers is to restore the imbalance in the soil.

Gardeners and gardeners have many of their own fertilizing recipes in their reserves, thanks to which their garden blooms beautifully and produces a bountiful harvest. For strawberries, there are also a huge number of different inexpensive folk methods of fertilizing, which many still use.

Folk methods for fertilizing plants in the garden are considered to be ash; usually they simply throw it away after cleaning the stove; boric acid, which is excellent against fungal diseases; iodine, which is not so expensive and is familiar to everyone for its medicinal properties; chicken feces

All of the above can be classified as agrochemicals. Since they are among the fertilizers of natural biological production. I use agrochemicals in gardens as fertilizing and protection against insects for plants, restoring soil balance, which allows us to grow a bountiful harvest. But you should be careful with such fertilizers, because with the wrong dosage you can aggravate the situation and even kill the plants.

Boric acid as a plant feed (strawberry)

It is best to feed strawberries during flowering, since at this moment they will be able to get enough of all the substances and get stronger.

If you use boric acid as a fertilizer, the stability of strawberries in bad weather will increase, the ovaries will be juicier and healthier. The beneficial properties of borax acid double when used on peat or soddy-podzolic soil.

Fertilizer preparation:

  • To prepare the necessary liquid you will need: Boric acid, which can be purchased at any pharmacy, it is sold (in doses) in the form of powder and liquid, potassium permanganate, which can also be purchased at the pharmacy.
  • Add one gram of boric acid and potassium permanganate to a ten-liter bucket filled with water (10 l).
  • The solution is ready, it can be used in early summer during flowering or in the fall after harvesting.

This solution supplies plants with oxygen, improves their nutrition with potassium from the soil, and improves their growth. Thanks to this feeding, the shelf life of the resulting fruits will be much longer.

Feeding with iodine

Iodine is commonly used to disinfect wounds on the human body and cuts. This medicine is indispensable in every first aid kit. But as it turns out, it can also be used in the garden to obtain a bountiful harvest. Iodine can prevent plant diseases, their rotting, the appearance of powdery mildew and many other diseases.

If you fertilize strawberry bushes with an iodine solution, the plant will bloom and bear fruit much better, since its immunity becomes much better, it actively resists diseases, it blooms faster and there are many more buds. In addition, a person receives an excellent and tasty harvest.

A lack of iodine in the soil can be noticed by how the plant grows; if the process is slow, then the plant’s body has an iodine deficiency, which can be prevented by fertilizing with a special solution. Iodine is not an expensive drug, so it can be purchased at any pharmacy at an affordable price.

Preparation of fertilizer with the addition of iodine:

  • For root feeding, add 1 mg of iodine to 10 liters of water and stir, then water the plants with it.
  • For spraying them, 10 drops per liter of water are suitable.

In both cases, it is necessary to use warm and non-chlorinated water. After watering and spraying, you can sprinkle the plants on the woody area, which will also have a great effect on their growth.
