Fertilizer application rules
When growing seedlings on the windowsill, tomatoes require several dressings. Mandatory fertilizers are applied in the following sequence:
- after growing up 2-3 large leaves;
- the following dressings are applied with an interval of 10-12 days;
- final top dressing is necessary 5-7 days before planting seedlings in a greenhouse or open soil.
A universal fertilizer is prepared from the following components:
- wood ash;
- organic liquid top dressing.
Organic (3 tbsp. l.) and ash (1 handful) must be diluted with water (10 l), the composition is thoroughly mixed.
With a lack of nitrogenous compounds, the foliage of tomatoes acquires a yellowish tint, the veins become reddish. To prevent nitrogen deficiency, it is recommended to spray the foliage with a mullein solution. The organic composition (1 l) is diluted in 10 l of pure water. Watering is carried out at the rate of 0.5 liters of solution per 1 plant. Dosage is reduced for small seedlings.
With the appearance of small spots of a golden hue on the leaves and deformation of the foliage, tomatoes need to increase the concentration of calcium in the soil. The seedlings are sprayed with ash infusion diluted in water (10 l) calcium nitrate (20 g) or water after boiling chicken eggs.
With an insufficient amount of iron, the leaves of tomatoes become yellow. With a deficiency of this mineral, chlorosis appears between the veins on the leaves, the plates acquire a brown hue, then brighten. It is necessary to spray the foliage with a solution of iron (sulfate) with a concentration of 0.25%.
Folding the sheets inward indicates a lack of fluoride. It is possible to compensate for the lack of a mineral by spraying seedlings with a superphosphate extract. You will need to dissolve the substance (20 tbsp. l.) in hot water (3 l), the composition is placed in a place with a high air temperature and stirred regularly. After 24 hours, the substance will dissolve. Suspension (150 g) is diluted in water (10 l), mixed with nitrogenous fertilizing to improve absorption by plants.
With an insufficient amount of potassium, tomato leaves begin to deform, the lower leaves are damaged. It will be necessary to add potassium sulfate (15 g) diluted in water (10 l) to the soil.
Top dressing options
With pale foliage and the appearance of a gray-green tint on the foliage, weakening of the shoots, the plants lack copper. To compensate for the lack of substance, it is worth feeding the seedlings with a solution of copper sulfate. The substance (1-2 g) is diluted in water (10 l). You can use copper sulfate (20-25 g), diluted in water (10 g).
When a large number of stepchildren are formed, the plants lack boron. The deficiency can be eliminated using a boric acid solution made in a proportion of 5 g of substance per 10 liters of water.
With a lack of magnesium, the foliage of the seedlings turns pale, light green and golden spots appear near the veins, the petioles become brittle. It is recommended to spray the foliage with magnesium nitrate (1 tsp) dissolved in water (10 l). l.).
To prevent the lack of mineral components, the seedlings are sprayed with an infusion of onion husks. You can use nettle leaves by filling the jar with them to 2/3 and adding heated water, the infusion is left for 2-3 hours. The composition is filtered, used for spraying tomato seedlings.
Before hardening the seedlings before planting in open soil, it is required to spray the foliage with a solution of the Zircon preparation to increase the immunity of the plant culture.
For stable growth of seedlings, it is required to provide plants with good illumination of the place, timely watering of the bushes.
To prevent the deficiency of mineral components, foliar feeding is carried out. A weakly concentrated solution of potassium permanganate is useful. You can use a solution of milk and water in a ratio of 1:10. 10-12 drops of iodine are added to the composition.
