Maintenance
🧺 Harvest
Harvest these now
These crops are coming ripe — pick regularly to keep plants productive.
Tomatoes
Pick as fruit colors up; harvest every 2–3 days to keep plants producing.
Peppers
Pick green or leave to ripen to red/yellow for sweeter flavor.
Eggplant
Harvest while skin is glossy; dull skin means it is past prime.
Tomatillos
Pick when fruit fills and splits the papery husk.
Sweet corn
Harvest when silks brown and kernels squirt milky juice when pressed.
Winter squash & pumpkins
Cure after the rind hardens and resists a thumbnail; harvest before hard frost.
Melons
Cantaloupe slips from the vine when ripe; watermelon sounds hollow.
Potatoes
Dig "new" potatoes after flowering; leave the rest until tops die back for storage.
🛠️ Maintenance
Keep the garden growing
Mid-season upkeep keeps plants healthy and productive.
📌 Water deeply and less often, mulch to hold moisture, side-dress heavy feeders, scout for pests, and succession-sow quick crops.
General July tasks
These apply broadly regardless of zone — a useful checklist alongside the zone-specific tasks above.
- ✓Harvest cucumbers, beans, and summer squash every 2–3 days to keep plants producing
- ✓Direct sow fall brassica crops: broccoli, cabbage, kale (cold and temperate zones)
- ✓Start fall tomato transplants indoors (Zone 9–10)
- ✓Deep water fruit trees and berry bushes in heat
- ✓Harvest and dry herbs before they flower
- ✓Apply second application of granular fertilizer to heavy feeders
- ✓Pull spent cool-season crops and replant with warm-season crops or cover crop
- ✓Harvest garlic when bottom leaves brown; cure in warm, airy location
⚠ 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
