When to plant broccoli

Start seeds indoors 8 weeks to 10 weeks before the last spring frost. Plant outside 2 weeks to 4 weeks before the last spring frost. For a fall crop, transplant 10 weeks to 12 weeks before the first fall frost. Fall broccoli is often sweeter than spring broccoli, since it matures in cool weather.

Hardy: shrugs off frost.
