Growing Information

• Days to maturity: 80-90 days from direct sowing
• Planting: Direct sow after last frost when soil temperature reaches 70°F; plant seeds 1 inch deep in hills of 4-6 seeds, 6-8 feet apart
• Spacing: Hills 6-8 feet apart; thin to 2-3 plants per hill
• Sun: Full sun (8+ hours daily)
• Zones: 3-11 (warm-season annual, requires long hot summer)

Harvest & Use

Harvest when the tendril nearest the fruit turns brown, the bottom spot turns creamy yellow, and the melon sounds hollow when thumped. Melons don't ripen after picking, so timing is crucial. The bright red, crisp flesh is incredibly sweet and juicy – perfect for fresh eating, fruit salads, smoothies, or grilling. Each vine produces 2-4 melons. Store whole melons at room temperature for up to 2 weeks, or refrigerate cut melon for 3-5 days.

Care Tips

Crimson Sweet watermelons thrive in hot weather and rich, well-drained soil. Water deeply and consistently – about 1-2 inches per week – especially during flowering and fruit development, then reduce watering as melons ripen for sweeter flavor. Mulch with straw to conserve moisture, suppress weeds, and keep fruit clean. Side-dress with compost when vines begin to run. Vines can spread 10-15 feet, so provide ample space. Companion plant with corn, beans, or nasturtiums for garden diversity.
