No gardener or vegetable grower will argue with the fact that it is necessary to prepare for sowing seedlings in advance.
First of all, it is worth carefully examining the existing inventory - what is left over from last year and what would not hurt to purchase this year.
First of all, this concerns cassettes that are used for growing many crops – the same pepper.
Last year's containers, as well as new ones, should be treated - first rinsed in water, and then in a solution of potassium permanganate.
Attention should also be paid to the soil mixture.
If you are preparing it yourself, most likely the necessary components – soil, ash, humus, sand, etc. – are stored in a cold place, from where they should be moved to a warm place.
Be sure to check the seeds you plan to plant for their availability and quality.
Finally, start preparing the place where the containers with tomato, pepper and eggplant seedlings will be located in the future, and inspect your fertilizer supplies to make sure you have enough of everything.
