Black Diamond Watermelon is a bold and dramatic heirloom with deep, dark green-almost-black skin and brilliant, sweet red flesh that can grow to a staggering 50 pounds under ideal conditions. The thick rind protects the sweet, dense interior remarkably well, making it a classic choice for market growers and home gardeners who want a truly impressive harvest. Grown in light, sandy soil with consistent watering, these melons develop exceptional sweetness and a classic, satisfying crunch.
