Black Diamond Watermelon Seeds for Planting - Heirloom, Non-GMO
These 50 Black Diamond Watermelon Seeds, at 7 grams, are a non-GMO and heirloom variety. Black Diamond watermelons are an excellent late-season open-pollinated option for both home and market growers. The dark blue-green rind is tough and bruise resistant, while the flesh is bright red with great, sweet and firm flavor. These melons average 14 inches across, weigh around 40 pounds, and are a popular shipping melon in the South, ready in about 85 days.
For cooler climates, Black Diamond watermelon seeds should be started indoors no sooner than a month before transplanting. Plant three seeds per peat pot, 1/4 inch deep, and provide heat to keep the soil temperature at least 80-85 degrees Fahrenheit. As soon as true leaves appear, cut off all but the strongest seedling, then transplant about a week after the last expected frost, putting two or three plants in each hill with 6-8 feet of space in all directions.
Gardeners in warm climates can direct sow watermelons as soon as the soil temperature reaches at least 75 degrees Fahrenheit, planting six seeds per hill with 6-8 feet of space in all directions. Thin to the strongest two or three plants as soon as the seedlings appear. Black Diamond watermelon seeds should always be planted in full sun and rich, loose soil. Young seedlings may benefit from black plastic to help warm up the soil.
These sweet watermelon seeds are perfect for the garden or growing in bulk. The Black Diamond variety is known for its exceptional late-season performance, producing large, flavorful melons with a tough, bruise-resistant rind. Whether you're a home gardener or a commercial grower, these heirloom, non-GMO seeds offer a reliable and rewarding watermelon crop.
Remember to adjust planting methods based on your local climate - indoor seed starting for cooler regions, and direct sowing for warmer areas. Proper soil preparation, spacing, and thinning techniques will ensure the best possible results from your Black Diamond watermelon harvest.
