Black Diamond watermelons are an excellent late-season open-pollinated variety for home and market growers. The dark blue-green rind is tough and bruise resistant, and the flesh is bright red with great flavor, sweet and firm. These melons average 14" across, weigh 40 pounds, and are a popular shipping melon in the South. Ready in about 85 days. Sowing: In cool climates, Black Diamond watermelon seeds should be started indoors, but no sooner than a month before transplanting; plant three seeds per peat pot, 1/4" deep. Provide heat to keep the soil at least 80-85 degrees F. Cut off all but the strongest seedling as soon as true leaves appear, and transplant about a week after frost; put two or three plants in each hill with a 6-8' space in all directions. Gardeners in warm climates will be able to direct sow watermelons as soon as the soil temperature reaches at least 75 degrees F, planting six seeds per hill with 6-8' of space in all directions. Thin to the strongest two or three plants as soon as the seedlings appear. Black Diamond watermelon seeds should be planted in full sun and rich, loose soil. Young seedlings may benefit from black plastic to warm up the soil.
