Troubleshooting
Longleaf Ground Cherry problems — and how to fix them
Longleaf Ground Cherry (Physalis longifolia) 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.
Invasive self-seeding
Plants drop fruits freely and self-seed prolifically. In garden beds this can become weedy. Harvest fruits before husks split, or contain plants with edging. Rhizome spread is also possible.
Flea beetles
Small round holes in young leaves are the hallmark of flea beetle feeding. Row covers at transplant and diatomaceous earth around stems provide control without pesticides.
Verticillium wilt
Soil-borne wilt can cause sudden yellowing and collapse in hot weather. Practise 3–4 year rotation away from other Solanaceae. There are no resistant cultivars for this species.
