Instructions

Start Black Diamond Heirloom Watermelon seeds indoors 4 weeks before transplanting outdoors. Take care not to disturb roots when transplanting. Or, sow a few seeds over a hill 9"-12" tall and 2' across. When plants are 3" tall, thin by cutting to 3 plants per hill. Use a balanced fertilizer to increase yield.

Planting Depth: 1"

Seed Spacing: Sow Black Diamond Heirloom Watermelon seeds roughly 8' apart, keeping rows approximately 6' apart.

Suggestions

Choose a site with good drainage, good air circulation and full sun. Watermelon is ready to harvest when skin on underside turns yellow and a thump with your knuckles produces a hollow sound.
