See all the characteristics
It is always very difficult to find a good variety of tomatoes for those regions where summer is short and cool. Nevertheless, such varieties are. Especially for the described conditions was created by domestic breeders, a cold-resistant tomato with the speaker name Leningradsky chill.

The main stages of growing seedlings at home
Preparation of seeds
Basic preparation methods: Warming, disinfection, soaking in growth stimulants, bubbling, hardening, germination. These technicians are aimed at different results and have a different purpose.
