"Black Diamond" grows on average 30-50 pound watermelon with some reaching up to 125 pounds. The dark, blue-green thick rind hides the sweet, firm bright-red flesh. These tough vigorous vines are widely used throughout the South. Start seed indoors 4 weeks before transplanting outdoors. Take care not to disturb roots when transplanting. Or, sow 6 seeds over a hill 9 to 12 inches tall and 2 feet across. When plants are 3 inches tall, thin by cutting to 3 plants per hill. Use a balanced fertilizer to increase yields. Ferry-Morse Seeds have been sold continuously since 1856 and are guaranteed to grow. Made in the USA.
