To get a full-fledged juicy harvest, you need to follow not only basic recommendations, but also know certain tricks that will help you grow tomatoes that are tasty and in sufficient quantity.
Tomatoes are especially vulnerable during the period of flowering and the formation of ovaries, which, with a lack of certain substances and violation of growing conditions, can suddenly begin to fall off. It was at this time that boric acid, a white powdery substance without taste and smell, which must be properly diluted, will help the gardener to stimulate the tomato ovary.

Effect of boric acid on tomatoes
If tomatoes are grown in a greenhouse or indoors, such treatment almost mandatory for them. In the absence of insects, pollination for the formation of ovaries is problematic. Some try to do it on their own using brushes or other tools, but the process is painstaking and time-consuming.
Principle of action for fruit set
It is much easier to resort to spraying the bushes with boric acid. This can be done both during the period of bud setting and during flowering. Better yet, do it twice during the specified periods.
Important! Boric acid contributes to the formation of ovaries and an abundant, active flowering.
The procedure is simple to perform, has a number of additional indications for use:
- prevents shedding of ovaries;
- with an excess of moisture, the boron solution will prevent fruit rotting;
- the flow of sugar increases to the fruit.
Boron is an effective fertilizer for tomatoes, which improves the appearance of the crop, helps its growth and fruit ripening.
Boron deficiency signs
The absence or lack of boron can lead to the following consequences:
- the inability of culture to form ovaries, and hence the appearance of fruits;
- reducing the resistance of tomatoes to many diseases and resistance to pests.
This is how plants suffering from a lack of boron look like:
- the bushes actively bloom, but the ovary does not form on them (if the boron deficiency is small);
- the tops of the plants become light and begin to curl downward;
- the main point of growth dies;
- young leaves begin to curl, large ones darken and break;
- there is an abundant growth of stepchildren;
- if the fruit is still formed, dark brown spots are visible on them with signs of tissue death.
To remedy the situation, urgently treat the bushes with a boric acid solution.
Signs of an overabundance of boron
An excess of this substance also has a negative effect on tomatoes:
- the leaves begin to cast a characteristic gloss;
- brown spots appear on them;
- the spots grow rapidly, the leaf dies off;
- the middle of the leaves bends characteristically, forming a dome.
If during processing the dose of boric acid in the solution is greatly exaggerated, the leaves will fall off, as will the ovaries.
How to prepare a solution
It is important to know the features of the preparation of the solution so that spraying does not lead to negative consequences.
Correct proportions and instructions
To begin with, prepare the foundation. In a glass of hot water, dilute 1 tsp.powder without top. After making sure that the powder is completely dissolved, the base is diluted in 10 liters of warm water. The solution is ready for spraying when not even small particles are present. It should not be harvested for the future, as sediment may fall out over time.
Depending on the purpose of the procedure, the proportions may be different. To prevent shedding of ovaries, 1 g of boric acid is dissolved in 1 liter of hot water. After the solution has cooled, it is carefully sprayed with a spray bottle.
To combat late blight, add 1 tsp to a bucket of warm water. powder... For best results, a week before such treatment, it is recommended to spray the bushes with a weak solution of potassium permanganate.
Tomatoes can be processed after boron iodine solution: A few drops are enough for a bucket of water.
How to properly process tomatoes
Tomatoes are sprayed according to the rules:
- the procedure is carried out in the morning or evening hours, direct sunlight can burn the wet leaves of the bush;
- it is recommended to use a spray bottle with small nozzles, tomatoes should seem to be enveloped in a fog of small drops, large drops are destructive for a plant;
- all plant fragments are sprayed: flowers, ovaries, plant stem and its leaves;
- the leaves are sprayed so that the solution gets on the back side, for this the bush is slightly tilted during the procedure;
- the temperature of the solution and the soil should be approximately the same;
- it is important to strictly observe the proportions, otherwise there is a risk of plant death or cessation of growth;
- it is recommended to first make a test spraying on one plant, if there are no negative consequences, treat all the remaining bushes.
It is recommended to spray tomatoes with boric acid three times per season. The first processing is carried out at the end of June: this procedure will serve prevention of late blight. It is important to process the plants no earlier than 2 weeks after planting the seedlings in open ground. The second time is sprayed at the beginning of budding. The third and last spraying is done during active flowering.
When grown in greenhouse conditions, treatment of bushes with boric acid is more important than when cultivated in open ground. In enclosed spaces, pollination is slower and worse, so boron is vital for the bushes.
Other nuances are also taken into account:
- if the greenhouse is not ventilated, a less concentrated solution will be needed, it will stay on the plant longer anyway;
- keep in mind that when the solution is applied under the root, it will be absorbed by the plant longer;
- there are Dutch feeding technologies in which treatments are carried out regularly every 9-10 days;
- it is important that the water temperature does not differ from that which is maintained in the greenhouse.
- they spray strong, viable bushes that have already taken root in the open field;
- it is not recommended to process after and during precipitation or before a hot, dry day;
- the formation of fruits in different varieties occurs at different times, it is advisable to spend and feeding;
- foliar dressing in the open field is much more effective than root;
- even with a large number of ovaries, they must be nourished, otherwise they may suddenly fall off.
Tips and tricks from experienced summer residents
Experienced summer residents recommend:
- do not spray seedlings - for fragile bushes it is difficult to maintain the proportions of the solution, they are easy to destroy;
- use complex micronutrient fertilizers to feed seedlings, boron is also present in them;
- do not spray the plants with a hot solution; cool it before use;
- in windy weather, the procedure is not recommended;
- some successfully add a few drops of iodine and a little milk to the boric acid solution - this combination will protect tomatoes from pests and diseases.
Despite the fact that boric acid in small quantities is harmless to humans, it still belongs to toxic substances. Therefore, to work with boric acid, you need to protect yourself:
- spraying carry out in closed clothes;
- use a mask and gloves;
- boron is very flammable, so it cannot be stored next to an open fire;
- do not allow contact with eyes and light particles of the substance;
- remove the remaining solution after use;
- the longer the powder is stored, the more toxic it is, it is better to use fresh.
Gardeners who sprayed tomatoes with boric acid agree that the most important thing in this procedure is the observance of proportions and processing technology.
Sergey, Rostov: «On the advice of friends, I began to spray tomatoes with boric acid during budding and at first I miscalculated: I made too much concentration of the solution, and the treatment gave the opposite effect: there were almost no ovaries. In the second season, on the contrary, I prepared a too weak solution, it simply did not give any effect, although there was a harvest. But in the end, he achieved his goal - the processing was carried out strictly according to the rules, three times. And the result exceeded all expectations - I have never had such a tomato harvest ”.
Irina, Belgorod: “I grow tomatoes on the loggia, we don't have a summer cottage. I learned how to get fruit. Only very small and a little. I read about boric acid. I took a chance and do not regret it. The bushes have become much more abundant, there are more ovaries, the bush itself is much more viable. The harvest literally pleases the eye. "
Timofey, Moscow: “I have been using boric acid for a long time and not only for tomatoes. Potatoes respond well to such spraying. I do the processing only twice - during flowering and the appearance of ovaries. I saw how my neighbor's tomatoes began to dry out after too intensive processing. Everything needs a measure. And the acid powder is of different quality, there is overdried, it is less effective. However, before each season I try to buy new bags. It is not expensive at all, and boric acid itself can be purchased without any problems. "
Many summer residents and fans of growing tomatoes on the balcony use boric acid solution with great success and do not regret it. Inexpensive white powder improves bush growth and accelerates fruit ripening. Observe the specified proportions and processing times, then the harvest in your beds will be plentiful.
