Watermelon Seed Planting Information:

Watermelons require a lot of space and a sunny location on your garden. Plant 5 to 7 seeds in a diameter outdoors in hills. Planting should occur 1 to 2 weeks after last frost. Plants grow 1 ft tall and vines spread up to 6 ft.

Soil Requirements:

Requires fertile soil in a well drained location in the garden. Apply much and grass clippings, or straw around base of plant. Add well-rotted manure and compost to soil.

Water Requirements:

Water well during dry and hot spells. Make sure plants get 1" water per week.

Fertilizer Requirements:

Use RootBlast, Vegetable Alive, and Slow Release Fertilizer when transplanting outdoors. Apply Miracle Gro every two weeks.

Harvest Tips:

Protect ripening watermelons from damp ground by placing them on boards. Tap the watermelon with your knuckles, and if it sounds hollow, it's ready. Cut watermelons carefully from plants to prevent damaging the vines.
