Planting & Care
  • Watermelons germinate in warm temperatures of 60°F to 95°F
  • Direct seed after last frost and the soil has warmed to an ideal 70°F and above. Plant seeds in hills 1/2 inch deep, 6 seeds per hill. Thin to 2 to 3 plants per hill. Space hills 4 to 6 feet apart.
  • Or sow seeds in rows - spacing plants 3 feet apart and rows 8 feet apart
  • When growing in areas with cooler temperatures or a shorter growing season, select varieties that are fast growing or start plants indoors 3 to 4 weeks before planting outside
  • When starting indoors, plant seed in individual peat pots so not to damage this plant's tender roots. Melons do not transplant well when their roots are disturbed. Set 2 to 3 plants per hill. Space hills 4 to 6 feet apart. Or set in rows, spacing plants 3 feet apart in rows 8 feet apart.
  • Mulch soil around plants to retain moisture and suppress weeds
  • Use a floating row cover to protect young plants from a late frost, to combat insects and to warm the soil. Remove once plants begin to flower to allow for bees to pollinate.
