Troubleshooting
Sugar Baby Watermelon problems — and how to fix them
Sugar Baby Watermelon (Citrullus lanatus 'Sugar Baby') 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.
Ripeness judgement
Watermelons do not sweeten after picking; harvest when the ground spot turns creamy-yellow and the tendril nearest the fruit dries.
Anthracnose and mildew
Leaf spots and lesions in humid weather; rotate crops, water at the base, and remove infected foliage.
Cucumber beetles
Feed on seedlings and flowers and spread bacterial wilt; protect young plants with row covers until flowering.
Poor fruit set
Cool weather or low bee activity drops flowers; hand-pollinate female blooms (those with a tiny fruit behind them) in the morning.
