Timely and proper nutrition is the key to a good strawberry harvest. She should receive fertilizer at least three times a year: in spring, at the beginning of the growing season, in summer, during flowering and in autumn, before preparing for winter. But, for some reason, most gardeners ignore such an important stage of feeding during the flowering period of strawberries - after all, it is then that she needs additional strength. In this review, we will consider how to feed strawberries during flowering with boric acid and iodine.

Why it is imperative to feed strawberries during the flowering period

Strawberries need nutrients all year round. This is especially true when it is grown in the same place for many years in a row. Additional nutrition is especially important during the flowering period, since the entire harvest depends on how the ovaries and inflorescences are formed.

The main purpose of top dressing is to restore the balance of nutrients in the soil. Choosing the right fertilizer depends on many factors, such as:

  • Soil composition.
  • Weather.
  • Plant condition.
  • The age of the plant.

During the flowering period, strawberries are actively developing and require special attention, care and attention. There are a large number of special mineral fertilizers, but folk fertilizers such as ash, boric acid, manure, herbal infusions, iodine, and chicken droppings are still popular.

Agrochemicals cannot be used during flowering, as they can accumulate in berries and subsequently cause poisoning in humans.

Agrochemicals are fertilizers of chemical or biological origin, which are used to nourish plants, soil, and also for pest control. Incorrect use at excessive dosages can do more harm than good.

During the flowering period, it is better to fertilize strawberries with organic matter by root or sub-root method. Root top dressing - the solution is applied to the soil, and foliar top dressing - the bushes are irrigated from above with nutrient compounds.

Top dressing during flowering must be done with only one type of fertilizer and once.

Apply all fertilizers only in diluted form and strictly adhering to the proportions. With all the safety of the funds, you need to try as much as possible not to get on the flowers and berries - spray only the stems and leaves, best of all the lower ones. Fertilizers should be applied to wet soil - the next day after heavy rain or watering and during daylight hours.

If strawberries are fed during flowering, then a large yield of large and tasty berries is guaranteed, because it is during this period that the greatest susceptibility to fertilization.

Boric acid for feeding strawberries during flowering in spring

Feeding strawberries with boric acid during flowering improves the nutrition of the ovaries and increases the plant's resistance to adverse weather conditions, as for potatoes and tomatoes. The fruits become sweeter and denser, so they do not crack from moisture. Boric acid works best as a fertilizer on sod-podzolic and peat soils.

Boric acid is an antiseptic that is sold in a pharmacy and has the following form: solution or powder. Usually, recipes indicate the dosage of boric acid in grams, and if you use an alcohol solution, then you need to determine in how many milliliters of solution there is 1 gram of boric acid. There is no standard, since solutions are produced with different boron contents. If powder is used in horticulture, then it must first be dissolved in a small amount of hot water.

Boric acid has neither color, nor taste, nor smell - this is its danger, because it belongs to poisons and its overdose can only be determined by the negative consequences.

Strawberries are perennials that require bright sun, rich and moist soil, which often grows mold and mildew. They negatively affect the taste and quality of the fruit, and in order to prevent this, it is necessary to treat its bushes with a solution of boric acid.

This must be done precisely during the flowering period - the first treatment, as soon as the buds begin to open, and the second at the end of flowering. There should be a break of approximately 10 days between them.

Boron deficiency signs

Strawberries are also treated with boric acid when they lack boron - an important trace element necessary for the normal life of the plant. This is reflected in the fact that:

  • Leaves dry around the edges.
  • The plant becomes lethargic even with good watering.
  • Leaves are deformed and crumble.

To feed strawberries, take 1 g of boric acid and 1 g of potassium permanganate per 10 liters of water. With this solution, you need to water the plants only at the beginning of flowering, or after the plant has ceased to bear fruit.

Fertilizer recipe

Also an effective recipe for such root feeding: 2 grams of boric acid, 2 grams of potassium permanganate and 1 glass of ash are dissolved in 10 liters of water - it has a double effect, since ash is an organic potassium phosphate fertilizer.

Use water not chlorinated, but purified by boiling or a filter, and it is also necessary to carefully adhere to the dosages so as not to harm the plant.

Boric acid as a fertilizer contributes to the supply of oxygen to the roots, it improves metabolic processes and increases the quality of potassium penetration from the soil into all plant fibers, which affects the shelf life of fruits.

To prepare the watering solution you need to take 1 sachet of pharmaceutical boric acid (10 grams) and dilute it in 30 liters of water. It is necessary to process this solution according to the already known rule - on the lower leaves.

Iodine is an irreplaceable remedy for strawberry care, recipes and recommendations

Iodine is a well-known antiseptic that is usually used for domestic purposes: disinfection of wounds and cuts. But it turns out that its use in the garden and vegetable garden can protect against many diseases, such as the appearance of late blight, rot, powdery mildew and more.

To get a good harvest of strawberries, iodine must be used as a fertilizer, because thanks to this:

  • plant immunity increases, they become more resistant to disease
  • more efficiently budding process;
  • increases number of ovaries;
  • improved safety and keeping quality of fruits;
  • yield increases, and the fruits become large and tasty.

Solution preparation, proportions

Iodine is a trace element that is found in many microorganisms and its presence in strawberry bites depends on whether it is in the soil and groundwater, if not, additional feeding is needed. Its lack is determined by such external signs - a delay in fruiting, rotting of the ovaries, the appearance of powdery mildew, gray rot.

The safe limit for the concentration of iodine in the plant is 0.1 mg per 1 liter of water - in recalculation, this is 20 drops for root feeding and 10 drops for spraying.

For root fertilization, it is better to make warm solutions and add wood ash to increase efficiency. With such an enriched liquid, you need to pour 500 ml under one get the desired result.

For the yield and quality of the fruit, it is necessary to process the plants with iodine during the flowering period. It is better to carry out this procedure in cloudy weather, or at night, since iodine in a duet with the bright sun can burn the leaves.

For root fertilization, you can use the following solution: Pour 1 glass of wood ash with 2 glasses of boiling water - leave for 2 hours. Add to this tincture 2 grams of potassium permanganate (not a solution, but crystals), 3 grams of boric acid, 10 drops of iodine and pour 10 liters of warm, settled (necessarily dechlorinated) water. The principle of the fertilization process: 1 250 ml glass under one bush.

The only drawback of precisely pharmaceutical iodine is that it is practically unable to enrich the soil. That is, they can only fertilize strawberries, and to enrich the soil, it is better to use mineral fertilizers with iodine, but not during flowering, but in spring.

Strawberries must be fertilized during flowering and this must be done only with organic and proven means. Iodine and boric acid are safe and effective remedies - the main thing is to adhere to dosages and recommendations for use, and then strawberries will delight you with a rich harvest of delicious and sweet berries.

Feeding strawberries with boric acid and iodine: how to breed and spray

Boric acid is a popular medicine that has found its use today for the treatment of various vegetable and ornamental crops. Thanks to it, it is possible not only to protect the plant from pathogenic microbes, but also to increase the yield and sugar content of the fruits. Boric acid is especially often used to process strawberries.... Such treatments can improve the taste of the berry.

In addition, they are less susceptible to rot and cracking due to excessive moisture. And although boron is not an alternative to any kind of fertilizer, it is considered a vital element for flora. But it will be possible to get a positive effect from such treatment only if the dosage and basic rules are observed.

Strawberry feeding rules

It is the spring feeding of strawberries that determines the quality of the future harvest. For this purpose, you can use mineral and organic substances, alternating between them.

When applying fertilizers, you must be guided by the following rules:

  1. In the first year of life, strawberries are not fed, since during planting, the holes were filled with fertilizers.
  2. In the second year, the first feeding is carried out when young leaves appear, around mid-April. It is best to use mullein or chicken droppings.
  3. During flowering, a second feeding is carried out with mineral fertilizers or folk remedies.
  4. The third time the strawberries are fed after harvest.
  5. The fourth feeding is carried out in late summer or early autumn.
  6. The fifth time, fertilizers are applied at the end of October before wintering.

For the best effect, root and foliar dressings are used alternately. The greatest need for nutrients is experienced by plants 2, 3 and 4 years of age. In the 5th year, old bushes are replaced with new ones.

During the budding period, plants require potassium. It is this element that should prevail in the second and third feeding before and during flowering. In order for nutrients to better penetrate to the roots, you should first loosen the soil around the berry bushes.

It is imperative to observe the dosage of fertilizers. If you overfeed the strawberries, it will fatten and will not tie the fruit. Due to a significant excess of fertilizer concentration, the roots can get burned and the plant will die. The nutrient solution is applied only to moist soil. Fertilizers in granules should not fall directly into the root zone, so that the thin suction roots that deliver nutrients and moisture to the plant are not damaged.

Recipe for feeding strawberries with boric acid: proportions of the drug

To make this simple yet very healthy spring strawberry dressing, we only need 2 ingredients. This is boric acid and ordinary water.

You can feed strawberries with boric acid no more than 3 times a season, while observing a break of 2 weeks, otherwise you can provoke an overdose of boron in strawberries. An excess of boron in strawberries is fraught with a slowdown in the growth of the root system of the plant, a deterioration in the development of the vegetative part, the appearance of burns on the leaves, manifested by yellow spots. The optimal scheme for feeding strawberries with boric acid is as follows:

  • first feeding - before flowering during the formation of young leaves
  • during flowering, until the buds have blossomed
  • at the beginning of the setting of berries.

It is worth noting that strawberries can be given both root and foliar feeding with boron.

Watering strawberries with boric acid in spring during flowering (root feeding)

Watering strawberries with boric acid in spring during flowering

Root feeding of strawberries with boric acid can be done both before flowering and during flowering, during the period of setting and even at the beginning of fruiting.

Root dressing is best done in the early morning or evening, but most importantly - on already moistened soil. If the soil is dry, the plants will be less able to absorb nutrients, and, even worse, the roots can get burned.

To prepare root dressing, we dilute 5 grams of boric acid in 10 liters of water and water the strawberry bushes under the root at the rate of 200 ml of solution per 1 bush.

Boric acid treatment of strawberries in spring during flowering

Foliar feeding of strawberries with boric acid is advisable to use if there is an acute deficiency of boron in plants. How to determine the lack of boron in strawberries, we told earlier.

It is worth noting that foliar dressing is absorbed by plants faster, which means that they begin to work faster. After all, the nutrient solution goes straight to where it is needed: flowers and ovaries.

Many gardeners have this question: is it possible to spray strawberries with boric acid during flowering and the formation of ovaries? The answer is yes, you can, the main thing is not to overfeed the plants and not to exceed the dose of fertilizer. Ideally, spray before the buds are full, at the very beginning of the flowering period.

To treat strawberries with boric acid, it is necessary to dilute 2 g of powder in 10 liters of water and spray the bushes. In this case, it is important to process the leaves on both sides. Processing should be carried out on a dry, windless day, either early in the morning or in the evening, after sunset, so that the leaves do not get burned.

Fertilizer in the fall - preparation for winter

Feeding strawberries in autumn is most important for young bushes. A feature of feeding this season is a decrease in nitrogen intake, so as not to provoke the growth of shoots before the onset of cold weather, and an increase in the proportion of potassium. Before applying, you should inspect the bushes to determine the need for nutrients. The presence of dry and spotted leaves and small fruits indicate a lack of nutrition, and whitish spots and sluggish foliage indicate an overdose.

In August, strawberries begin to lay flower buds of the future harvest. At this time, it is recommended to feed it with urea, and a rotted mullein is introduced under the roots. In order not to overdo it with organic matter, you need to take into account the soil on which the culture grows, how much humus is contained in the substrate.

At the beginning of autumn, it is advisable to feed the strawberries using liquid fertilizers, and in October it is better to use dry preparations.

After the last autumn fertilization, the rows are mulched with straw, sawdust, sheet compost or other insulating materials.

You can understand that a strawberry plantation is experiencing boric starvation by several signs.

First of all, you should take a closer look at the foliage. With a small presence of boron, the leaves become curved, and their edges begin to die off.

A plant starving for this element stops knitting, the berries on it are smaller, as a result of which the total yield of the plot with strawberries is significantly reduced.

The lack of boron can also be determined by the taste of the berries: they become more watery, the sweetness is not felt at all.

The better to feed strawberries during flowering and fruiting, fertilization rules

It is known that without feeding strawberries, there will be no good harvest of berries. Fertilizers must be applied during the entire growing season, including during flowering and fruiting.At this time, plants also need nutrients, as during the growth period. Find out how you can feed strawberries during flowering and fruiting, in what doses to apply fertilizers.

Why feed strawberries

In order for the berries to form, reach a characteristic size, taste, aroma and color, become juicy, you need to provide the bushes with food in the amount they need. Especially large-fruited and very prolific varieties, as well as remontant strawberry varieties, need additional fertilizing during flowering and fruiting.

The number of applications depends on how fertile the soil is and the age of the plants. When planting strawberries, as you know, fertilizers are applied either during the preparation of the site, or directly into the holes. This amount is enough for the whole year, no more fertilization is required. But then fertilizer must be applied every year, because the land is depleted.

Rules for root and foliar feeding of strawberries

Root irrigation is carried out by dissolving fertilizers in water and watering the plant with a solution or scattering granules over the soil surface and then burying them into it by shallow loosening. Then watering is carried out.

Root feeding with a solution of mineral fertilizers is carried out only after the previous irrigation with plain water. This must be done so that the concentrated liquid does not burn the roots. Watering time is evening or morning. Moreover, if during the application of fertilizer it got on the leaves, it is important to wash off the preparations with clean water from them.

A solution for foliar spraying is prepared by taking 2 times less granules than for root irrigation. Sprayed in cloudy, but not rainy weather, without wind, be sure to wet the underside of the leaves. Foliar dressing is also carried out on the leaves of flowering strawberries with boric acid.

Top dressing of strawberries during budding and during flowering

At this time, the foundation for the future harvest is laid. Top dressing of strawberries in the spring before flowering is carried out with ordinary ash. It contains all trace elements, with the exception of nitrogen.

Ash should be from burning only vegetation, but not stove, not from burning wood with paint, plastic, newspapers. It is scattered around each bush, spending a handful of powder on it.

Then slightly loosen with a hoe and watered on top.

Spring feeding with ammonia (end of the first - beginning of the second spring month) reduces the risk of diseases, infectious and fungal, promotes the growth of strawberry greens. Composition: for 10 liters of 40 ml of alcohol and 1 liter of soapy water. The solution is applied at the root. Treatment with ammonia is also carried out after harvesting the fruit. The composition of the dressing: for 10 liters of 40 ml of ammonia and 5 drops of iodine.

Strawberries throw out peduncles, depending on the variety and climate of the area, throughout May. For good flowering, she needs potassium, zinc, boron and magnesium. The easiest way is to feed Victoria with potassium nitrate, which contains this element and nitrogen. The solution is prepared from 1 tsp. substances per 10 liters of water, pouring 0.5 liters under each strawberry.

Saltpeter can be replaced with potassium monophosphate (take 1 tbsp. L. Per 10 l), potassium sulfate (sprinkle 25-30 g per 1 sq. M.), Superphosphate (no more than 40 g per 1 sq. M.). Another recipe: take 2 g of potassium sulfate and potassium permanganate and 1 g of boric acid per 1 liter of water. Potassium humate can be used.

It is better not to use chlorine-containing potash fertilizers.

It is possible at this time - before flowering - to use the preparation Ovary, in which substances are selected that contribute to an increase in the number of peduncles and increased formation of an ovary. The drug works even with bad summer insects in cold or rainy weather. To attract bees, you can spray the plants with water and honey (1 tablespoon per 1 liter).

You can feed flowering strawberries using Agros, Kemira Lux, Rubin, Hera, MagBor, etc. From folk remedies known for their effectiveness, feeding strawberries during the flowering period can be done with a yeast solution. In addition to them, the infusion can be prepared from weeds, use a solution of boric acid or an iodine solution.

Top dressing of garden strawberries during the formation of the ovary and fruiting

Foliar spraying with mineral fertilizers, when the strawberry bears fruit, is not carried out. Only root applications remain.

You can feed the strawberry bushes after flowering with complex fertilizers, but those gardeners who adhere to more ecological growing of berries prefer preparations made from natural products, for example, from the waste products of earthworms.

They may not be as fast-acting, but they are completely harmless. For feeding strawberries during the fruiting period, use Gummy Universal and Gummy Potassium.

Recipes for folk remedies for feeding strawberries

It is no secret that vegetable growers who prefer to grow crops without chemicals have long and successfully used products prepared according to popular recipes to feed their plants. Ingredients for their preparation can always be found on your farm.

Nettle infusion

Young spring nettle is an excellent green food for cultivated plants.

To feed the garden strawberries, an infusion is prepared: freshly picked grass is cut into pieces, placed in a bucket or in a small barrel in dense layers, water is poured into them, some crackers or old jam are added and placed in a warm place for 1 week to ferment.

Before watering, the nettle infusion is diluted with water 1 to 10. The liquid is poured under the root of the bush, 0.5 liters per unit. Top dressing is effective before flowering. Plants can be sprayed with this solution during the fruiting phase. You need to take 0.5 liters of solution per bucket.

Bird droppings or cow dung

Infusions based on these components show good performance on sandy loams and loams with a low salt content. They are prepared in a standard way: diluting 1 part of mullein in 10 liters of water or 1 part of bird droppings in 15 liters of water.

Top dressing is applied in early spring, adding urea (1 box of matches per 10 liters of water) and 0.5 tbsp. wood ash. During budding, the bushes are watered with the same solution. After 10 days, water the mullein with the working solution, without other fertilizers. When the fruits begin to pour, watering is no longer carried out with these infusions, since an excess of nitrogen leads to the appearance of gray rot and wateriness of the fruits.


Yeast solution can be prepared from both fresh and dry yeast. The composition of the folk remedy in both cases will be different.

WayRecipe remedy
1Take 100 g of yeast per 10 l of warm water. Insist for only 1 day. Water 0.3-0.4 liters under the bush.
2Take 5 g of dry granules, 0.5 l of heated water, 1 tbsp. l. Sahara. Insist 3-4 hours, then pour into 10 liters of water. Water the strawberries in 1-1.5 tbsp. for each plant.
3In a 15 liter container, put 1 liter of chopped nettle, 1 handful of dry bread, 1 tbsp. l. yeast. Insist 2 days. Consumption - 1 tbsp. on a strawberry bush.

Yeast feeding is carried out 2 times: before flowering and at the end of the strawberry collection.

Wood ash

This is an excellent fertilizer, it is often watered and processed with all garden crops and strawberries as well. When feeding strawberries with ash, the soil is saturated with all the chemical elements necessary for it.

When to applyHow to apply
In April and early next monthScatter on the ground near the bush, loosen and water. The norm is 1 handful per plant.
During the period of berry growthPrepare infusion: 1 tbsp. Dissolve ash powder in 1 liter of hot water, leave to infuse for 2 days. Pour the liquid into 9 liters of water, pour 0.5 liters on strawberries.

Ash not only feeds the plants, but can also protect them from gray mold damage. In the cold and wet season, dust the strawberries with sifted powder to reduce the likelihood of illness.

Boric acid

You can fertilize strawberries with this tool during flowering. From this, many fruits are tied on it, the flowers are not sprinkled, the berries become denser and sweeter, the plants become more resistant to powdery mildew, bacteriosis, late blight.

From boric acid, you can prepare funds according to the following recipes

Dissolve 2 g of the drug in 10 l of waterStrawberries are fed with boric acid during flowering on the leaf. Preparation of a solution with acid: 0.5 tsp. dissolve first in a small amount of hot water, then pour into a bucket of water. Spraying with boron increases the yield by 1/3.
Dissolve a little acid in 10 liters (on the edge of a knife) and a little potassium permanganate crystalsAt the beginning of flowering, watered with 0.3 liters under the bush.
Add 1 tbsp to the same composition. ashWater in the budding phase, at the root.

The boron element helps garden and horticultural crops to extract and assimilate chemical elements and other nutrients from the soil, increasing productivity.

Strawberries are sprayed with iodine solution, starting from the budding stage. In total, 3 sprays are made with an interval of 1-1.5 weeks. Recipe: drip 7-9 drops of alcoholic tincture into 10 liters. Spraying with iodine will not only feed the bushes, but also protect them from some diseases.

Feeding strawberries is essential if you want to get a good harvest. You can use various fertilizers of mineral or organic nature, prepare products according to recipes common among the people.
