    Make a planting map for August. Tomatoes, peppers, brassicas, lettuce, root crops all go in over the next 8 weeks. Soil amendments and irrigation prep happen now.

  2. Keep heat-survivor crops productive

    Daily harvest of okra and southern peas keeps plants producing. Let pods over-mature and the plant stops setting new fruit.

  3. Watch for hurricane prep season

    August-October is hurricane season. Stake young trees, secure rain barrels, and plan how to protect tender transplants from high winds.

Cabbage 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.

Cabbage needs ~1,340 GDD — county provides 4,522 GDD Excellent fit
