Watermelons are warm season fruits that grow on sprawling vines. Due to their vining habit, watermelons need lots of room and are not very well suited to small garden spaces. The plants have large leaves that protect the younger melons on the vine

Plant after danger of frost has passed. Side-dress with nitrogen fertilizer when vines begin to run. Fertilize well and keep soil moist at all times. Placing a mat of straw under the watermelon will prevent the bottom of the watermelon from rotting as it continues to grow.

Watermelons are long crops and mature in 70-100 days from seed. They can be grown from either seed or transplants. Young transplants are typically 21-28 days old. Transplants will produce watermelons 2-4 weeks earlier than watermelons planted by seed directly into the garden.
