Troubleshooting
Ground Cherry problems — and how to fix them
Ground Cherry (Physalis pruinosa) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Telling when fruit is ripe
Berries are only sweet and safe when fully ripe and the husk turns papery; fruit naturally drops to the ground when ready. Discard green, unripe berries.
Flower and fruit drop
Triggered by drought stress or temperature extremes during bloom. Keep moisture even and mulch the root zone.
Sprawling, messy habit
Stems flop and dropped fruit can rot on damp soil. Mulch underneath, leave room to spread, and harvest fallen fruit promptly.
Flea beetles and aphids
Chew small holes in leaves or cluster on new growth. Use row cover early in the season and rinse or treat aphids with insecticidal soap.
