    Melons and watermelons are full of vitamin C, and are among the most prized in the vegetable garden. Weather is very important. The warmer it is, the sweeter the melons will be.

Thin to one seedling per pot. Transplant watermelon plants outdoors after all risk of frost in rows 4-6’ apart with 36”(melons) – 48”(watermelon) between plants. For direct seeding, wait till all risk of frost has passed and soil has warmed.
