Plan the fall garden
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.
-
Keep heat-survivor crops productive

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.
