How to Know When Ice Box Watermelons Are Ripe

Icebox watermelon is a small variety of watermelon that typically weighs between 8 and 10 pounds. It became readily available to consumers in 2005. Because of its size, it fits well in the refrigerator, hence the name. An icebox watermelon -- like all watermelons --is best harvested when ripe. Expect to harvest an icebox watermelon approximately 78 days after planting, making sure it meets several criteria first to ensure it is ripe enough for picking.
