  2. Direct-sow brassicas indoors or in shade

    Broccoli, cauliflower, cabbage, Brussels sprouts germinate better in cooler conditions. Start indoors or under shade cloth, transplant in September.

Microgreens Heat Requirements (GDD)

What are Growing Degree Days (GDD)?

Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.

Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.

Microgreens needs ~192 GDD — county provides 4,441 GDD Excellent fit
