Question
I want to grow begonia plants.  If I want to plant them outside in early April, when do I plant the seeds.

Answer
Hi Anna,
Thanx for your question.  Begonia seeds are tiny, like dust.  They should be planted on top of soil in a pot indoors about 12 weeks before the last frost. The should be kept warm about 75-80癋/24-27癈.  Begonias are not cold hardy so don't plant them outdoors if temperatures are still falling below 50癋/10癈.  I hope this helps.
