Planting & Care

Sow Charleston Grey Watermelon seeds directly outdoors after the last frost date, when soil has warmed to at least 70°F. Plant seeds 1 inch deep in hills or rows, spacing 3-5 feet apart. For earlier harvests, start seeds indoors 3-4 weeks before transplanting, using biodegradable pots to avoid root disturbance. Keep soil evenly moist during germination and establishment. Once vines begin to run, water deeply once a week, providing about 1-2 inches of water per week. Mulch to retain moisture and suppress weeds. Fertilize lightly when vines start to spread, and reduce watering as fruits mature to concentrate sweetness.
