Boron is one of the most essential trace elements for nightshade plants. Let's talk about how to properly process tomatoes with boric acid, how safe the substance is, what nuances you should not forget about when diluting the solution.
What gives boric acid to tomatoes?
Boron helps tomatoes develop properly. The microelement increases the flow of sugar to the plant, this increases the yield and improves the taste of vegetables. In addition, spraying with a solution of boric acid stimulates the development of roots and bushes.
Boron treatment helps to preserve the ovaries and promotes the formation of new shoots.
Why do tomatoes need boron?
Feeding is carried out several times during the season. Seeds must be treated before sowing, as this procedure protects seedlings from infections. During flowering, foliar spraying enhances the formation of inflorescences and restrains their shedding. During the fruiting period, it helps to protect tomatoes from spoilage, improves taste properties.
Signs of a lack of a substance
The lack of a trace element is typical for depleted sandy or sandy soil. In such soil, boron usually does not linger, and crops feel its deficiency.
Plants that need boron are as follows:
- stems become brittle;
- leaf plates lose color, deform;
- the tops are covered with brown or light spots;
- the stem turns black or dries up;
- culture blooms poorly;
- inflorescences and ovaries fall off.
Proper preparation of the composition
Before diluting boric acid, read the instructions on the package.
To prepare the composition, use warm water, as the substance does not dissolve in cold liquid.
Make sure that the crystals dissolve well, otherwise burns may form on the leaves. Carry out the treatment with a cooled solution.
Sequential processing steps
Boron is used for seed processing, spraying and watering. When twisting the leaves on the bushes, they should be irrigated; if the foliage crumbles - irrigate with the prepared solution.
Seed processing
Seed treatment with boric acid is a good prevention of many diseases. Sequencing:
- Take the substance (0.2 g), dilute in warm liquid (1 l).
- Drain the composition into any dishes.
- Put the seeds on cheesecloth and place in liquid.
- Leave the seeds in the solution for a day.
Before planting seedlings in a permanent place, treat the soil with a solution of boric acid (2 g / bucket of water).
Watering
Perform root dressing with this solution: dilute the dry matter (10 g) in a bucket of liquid. Before carrying out the procedure, water the soil abundantly with water so as not to damage the root system.
Moisten the earth with a solution next to the bushes and in the aisles. One liter of the composition is enough to process 1 square. m of soil.
spraying
The most effective is foliar processing. For the procedure, use a spray bottle.
The process is carried out in three stages:
- The area is treated with a solution of potassium permanganate.
- After about seven days, a solution of boric acid is applied.
- After seven days, they are treated with iodine solution.
To protect against late blight, spray tomatoes with a solution consisting of 1 tsp. l. boron and water (10 l). To preserve the inflorescences, the following composition is suitable: a substance (10 g) per bucket of liquid.
Carry out treatments in calm weather at an air temperature of +25 °C.
Boric acid is an effective and inexpensive top dressing for tomatoes. Increasing the dosage of boron in the solution will not bring the desired results - on the contrary, the bushes may die from an overdose. Fertilize tomatoes with boron only during flowering and fruiting. When used correctly, boric acid will help increase yields and protect plantings from disease.
