The Q&A Archives: Germinating Annuals

Question: When is the best time to plant most annuals for early summer bloom if I start them in a unheated grenhouse? In Washington it rarely freezes past mid-January. I have a heated propagation box (6' x 2') that is covered with glass. I would like to plant Geraniums and to enjoy in June if possible. Last year they did not bloom until July or August.

The seed should be covered..
