Maintenance
🧺 Harvest
Harvest these now
These crops are coming ripe — pick regularly to keep plants productive.
Pick as fruit colors up; harvest every 2–3 days to keep plants producing.
Pick green or leave to ripen to red/yellow for sweeter flavor.
Harvest while skin is glossy; dull skin means it is past prime.
Tomatillos
Pick when fruit fills and splits the papery husk.
Harvest when silks brown and kernels squirt milky juice when pressed.
Cure after the rind hardens and resists a thumbnail; harvest before hard frost.
Cantaloupe slips from the vine when ripe; watermelon sounds hollow.
Dig "new" potatoes after flowering; leave the rest until tops die back for storage.
🛠️ Maintenance

Mid-season upkeep keeps plants healthy and productive.
