How to Freeze Watermelon

This easy step by step guide with pictures shows how to freeze watermelon at home to preserve this sweet melon for the months to come. Frozen watermelon is wonderful in smoothies and sorbet for a healthy treat.

Watermelons are easy to grow in the home garden during the warmer months as long as you have the room. They will need 1 yard x 1 yard (1m x 1 m) of space for the vines to spread out. For more information see this guide to Growing Watermelons from Seed.

You may find several watermelons are ready to be picked at once which makes freezing a great option. Watermelons are ripe when the stem or leaves begin to wither and die off.

If you are not able to grow your own then specials can be found in the middle to late summer. It is usually cheaper to buy whole watermelons than cut. Simply freeze any you can’t eat.
