Therefore, it is very important to pour enough water into the furrow holes before sowing the seeds - it will not interfere. After planting the seeds, the area can be covered with plastic wrap. As soon as the shoots appear, the film is removed.

Older plants can be planted in other places.We must not forget about fertilizer, for which the most common mullein or mineral complex fertilizers will do.

Three years ago I planted asters in my garden. They pleased me with the flowering, but the next year I didn’t succeed with planting. What a surprise it was when, closer to autumn, I saw these colorful flowers again... They bloomed the same way this year. Is that possible?
Why isn't it possible? It’s just that seeds have formed on the asters that you planted. The seeds fell into the ground and sprouted on their own the next year.
