Question: How well will I do growing watermelons in a home garden? When should they be planted?

Answer: Watermelons take large amounts of garden space, often as much as 100 square feet per plant. Grow them only if you can give them that room to grow. Plant them a week or two after the last killing freeze date for your area. Watermelons are not as productive in fall gardens. They really prefer the hot days of early summer.
