- throughout the entire period of growing tomato seedlings, it is necessary to monitor the soil moisture and not to allow either excessive wetting of the earthen coma, or its strong drying;
- if seedlings are stunted in growth or development, it is recommended to fertilize with special complex fertilizers for vegetable crops.

- the standard scheme for planting seedlings on ridges is approximately 40x60 cm;
- Before planting, the prepared planting holes must be abundantly moistened by spilling with water with the addition of potassium permanganate;
- planting depth depends on the height of the aerial part and the size of the root system of seedlings, but it is recommended to deepen the tomato bushes to the first true leaves, which will allow the plant to form additional roots that improve nutrition and increase the productivity of the garden crop;
- to the stage of full survival, it is desirable to provide plants with sufficient moisture and shading from the sun;
- after the plant takes root and starts to grow, it is best to form the aerial part in two stems;
- Further care for the vegetable crop consists in the timely implementation of irrigation measures, fertilizing, loosening, weeding and in the prophylactic treatments of tomato bushes in order to protect against diseases and plant parasites.
