Plant watermelon from late spring to early summer, once soil temperatures reach 70° F or above. Space watermelon 3 to 5 feet apart in nutrient-rich, well-drained soil with a pH of 6.0 to 6.8.

Depending on the variety of watermelon, it can take between 70 and 100 days to go from planting to harvest.
