Beat the summer heat

📌 Shade-cloth tender crops, water deeply at dawn, mulch heavily, and grow heat-lovers like okra, sweet potato, and Malabar spinach. Solarize empty beds for fall.
General July tasks
These apply broadly regardless of zone — a useful checklist alongside the zone-specific tasks above.

⚠ Watch-outs for July
- ⚠Heat stress causes tomatoes to drop blossoms and lose flavor — mulch and water consistently
- ⚠Powdery mildew starts on squash, cucumbers, and phlox in July — treat at first sign
- ⚠Squash vine borers emerge in most zones — check stem bases and treat if found
- ⚠Water early in the morning to reduce evaporation and fungal disease
