  1. Plant fall tomatoes & peppers

    Late August is your fall transplant window. Pick heat-tolerant determinate tomatoes (Heatmaster, Solar Fire, Phoenix). They'll set fruit through fall.

  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.

  3. Refresh mulch & drip lines

    Check drip irrigation for clogs (afternoon thunderstorm grit). Top off mulch in all beds before the cool-season crops go in.

Thai Basil 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.

Thai Basil needs ~1,516 GDD — county provides 7,808 GDD Excellent fit
