Black Dimond Watermelon

Black Diamond Watermelon is a classic heirloom variety known for its enormous size and striking appearance. These watermelons feature smooth, dark green—almost black—rinds that protect their sweet, juicy, bright red flesh inside. Fruits typically weigh 30–50 pounds or more, making them a favorite for gardeners who love big harvests. Black Diamond watermelons mature in about 85–100 days and thrive in full sun with rich, well-drained soil. They require plenty of space for their vigorous vines and consistent watering for optimal growth. This variety is prized for its old-fashioned sweetness and crisp texture, perfect for summer picnics and refreshing desserts. Packed with hydration and nutrients, Black Diamond remains a beloved choice for home gardens and traditional Southern growing.
