Troubleshooting
Miniature Pumpkin problems — and how to fix them
Miniature Pumpkin (Cucurbita pepo 'Jack Be Little') 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.
Powdery mildew
White powdery coating on older leaves, especially late season. Space plants widely, avoid overhead watering, and treat early with potassium bicarbonate or neem oil spray.
Squash bugs
Grey-brown insects and bronze egg clusters on leaf undersides cause wilting. Remove eggs by hand, apply neem oil, and use row cover early in the season before flowers open.
Blossom drop
Male flowers naturally drop after releasing pollen. If female flowers drop (identifiable by the tiny proto-fruit at the base), the cause is usually temperature extremes above 35°C (95°F) or insufficient pollinator activity — hand pollinate in the morning.
