Can plant onions

If the greenhouse is not heated, the plants are planted in a certain time. In April, you can plant onions and dill, cabbage and radishes for seedlings, while to protect against frosts it is recommended to close them with thin non -woven material. In early May, the seedlings of cucumbers, tomatoes and eggplants are planted for hardening, but only for a day — at night they are cleaned in warmer places. The final planting of seedlings occurs no earlier than the end of May.
