I want to start some seeds indoors this spring. How soon can I sow broccoli and tomato?
For broccoli, start eight weeks before the last spring frost. The seed will sprout in three to 10 days at 70 to 80 degrees F. Then cool seedlings to 60 to 70 degrees F. Tomatoes require less time, from five to seven weeks before the last spring frost. Seeds sprout in six to 14 days at 75 to 80 degrees. Grow seedlings at 60 to 75 degrees F.
