About Watermelon

Watermelons love heat space and sun — they are a rewarding crop but need a long warm season.

Start indoors 4 weeks before last frost. Transplant carefully — watermelons hate root disturbance. Give them maximum space. Use black plastic mulch to warm soil. Choose icebox varieties for containers.
