When to plant seedlings in 2026

When sowing any seedlings, it is important to consider several nuances. First: the quality of the soil and planting material will determine what kind of seedlings you get. It is important that the soil is not acidic.

«It is important to remember that pots must have drainage. It is worth preventatively watering the soil with potassium permanganate for additional disinfection,» explained Lyudmila Shubina, an agronomist and candidate of agricultural sciences. «Each crop has its own age when seedlings should be transplanted to a permanent place. For cucumbers, for example, it is 30 days, for peppers 65–75 days, for tomatoes it can be 50 days.»

Both too young and overgrown seedlings will deprive the gardener of part of the harvest. Therefore, planting dates are very important to consider.
In the European part of the country and in the Urals, these dates shift by 1–2 weeks due to earlier planting, meaning sowing can be done earlier. One must be guided by the climate.
«In Siberia, the threat of late frosts remains until June 10, so there is no need to hurry either with planting seedlings or with sowing them,» the agronomist warned.
