Troubleshooting
Moon and Stars Watermelon problems — and how to fix them
Moon and Stars Watermelon (Citrullus lanatus 'Moon and Stars') 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.
Long season requirement
These large heirloom melons need a long hot summer; in cooler regions start indoors and choose your warmest site.
Ripeness judgement
Picked too early they never sweeten; harvest when the ground spot is creamy-yellow and the nearest tendril has dried.
Anthracnose and mildew
Foliar disease in humid weather causes leaf lesions; rotate crops, water at the base, and remove affected leaves.
Cucumber beetles and bacterial wilt
Beetles damage seedlings and spread wilt; use row covers on young plants until flowering begins.
