Watermelon-Black Diamond Seed

$2.99

Watermelon 'Black Diamond' is a large, high-yielding variety known for its dark green rind, juicy red flesh, and sweet flavor. Maturing in about 80-90 days, it produces round to oblong fruits weighing 30-50 pounds. Thriving in full sun with well-drained, nutrient-rich soil, sow seeds directly outdoors 1 inch deep, spacing plants 3-5 feet apart in rows 6-8 feet apart after the last frost. Keep soil consistently moist but not waterlogged. Harvest when the underside turns yellow, and the tendrils near the stem dry out. Perfect for fresh eating, ‘Black Diamond’ is a classic summer favorite.
