Don't limit yourself to buying seeds, soil and pots for seedlings. You can't do without them, but no one will give you a 100% guarantee that you will grow strong seedlings.
Include the following medications in your priority shopping list.
Anastasia Kovrizhnykh, an expert of the online publication "BelNovosti", a scientist agronomist and landscape designer, told us what preparations need to be purchased for sowing and at the beginning of the summer cottage season in general.

Vitamins
These are preparations that contain macro- and microelements, as well as essential amino acids that will help seedlings survive transplantation and protect them from diseases (for example, aminosil).
Microbiological preparations
It is imperative to stock up on additives that contain beneficial soil microorganisms.
They protect against the spread of pathogens and improve the condition of the soil, increasing fertility (for example, atlas).
Biofungicides
These are preparations based on Trichoderma, which destroy pathogenic fungi, protecting against rot, anthracnose and other diseases (for example, gliocladin, phytosporin-M, etc.).
Stimulants and growth regulators
The preparations help seedlings develop and recover after transplantation. Kornevin is in demand among gardeners.
It would be a good idea to purchase means to prevent seedlings from stretching – growth regulators. They prevent stretching and promote root development.
Pest control
These can be either biological preparations (phytoverm) or more powerful insecticides.
It won’t be superfluous to have Epin-extra, which helps gardeners during transplantation and temperature changes, as well as succinic acid.
It helps improve the condition of soil microflora.
