The key to keeping cut watermelon fresh is to keep it cool and dry. You see, when watermelon is exposed to heat and moisture, it becomes a breeding ground for bacteria and mold, which can cause it to spoil quickly. By storing it in the fridge, you're essentially putting the brakes on this process and keeping your watermelon fresh for up to 3-5 days.
But here's the thing: you don't need to refrigerate watermelon if you're planning to eat it within a day or two. In fact, watermelon can be stored at room temperature for a short period of time without losing its flavor or texture. Just make sure to keep it away from direct sunlight and heat sources, and you're good to go!
