If you’re like me, you’ve struggled with knowing when a watermelon is ripe. This is my third year growing watermelon, and I’ve just now figured it out. The old-timer’s method of tapping on the rind, listening for the “hollow sound,” just didn’t work for me. It’s too subjective. I thought I was a hopeless case on this until I saw a video from Colorado State by an extension employee who said she couldn’t get it right either, then proceeded to show a more objective way to know when a watermelon is ripe. Bingo! I’ve finally got it right. When is a watermelon ripe?
