100 Black Diamond Watermelon Seeds - 14 grams. Non-GMO and Heirloom variety.

Black Diamond watermelons are a late-season open-pollinated variety popular among home and market growers. The tough and bruise-resistant dark blue-green rind encases bright red, sweet, and firm flesh with a great flavor. These melons reach an average size of 14" across and can weigh up to 40 pounds, making them a preferred shipping melon in the Southern region. They are ready for harvest in approximately 85 days.

Sowing Instructions: For those in cooler climates, it is recommended to start Black Diamond watermelon seeds indoors about a month before transplanting. Plant three seeds per peat pot, 1/4" deep, and provide enough heat to maintain a soil temperature of 80-85 degrees Fahrenheit. Once true leaves appear, select the healthiest seedling and transplant it about a week after the last frost. Space two or three plants in each hill, with 6-8 feet of space in all directions.

If you are in a warmer climate, you can directly sow the watermelon seeds once the soil temperature reaches a minimum of 75 degrees Fahrenheit. Plant six seeds per hill, and thin to the two or three strongest seedlings once they sprout. Ensure that the plants are in full sun and planted in rich, loose soil. Consider using black plastic to help warm up the soil for young seedlings.

Get your hands on these sweet Black Diamond Watermelon seeds to grow your own delicious melons in your vegetable garden. Purchase in bulk for a bountiful harvest.
