Harvesting and Storage Tips

Checking a watermelon to figure out if it’s ripe is an essential first step of the harvesting process.

Rather than thumping a crimson sweet watermelon to figure out when it’s ripe, check the color of its stem.

When the stem and the tendrils surrounding the stem are brown and start to shrivel up, the watermelon is ready to harvest! If the stem is green, this means the watermelon is still growing. Don’t pick it yet!

Other clues can help you figure out if it’s time to pick your watermelon. For example, the color of the rind tells you when it’s ready to harvest.

A fully ripe watermelon will likely fade to a slightly duller green, while an unripe watermelon will have more of a sheen.

You can also look at the underbelly of the watermelon to evaluate its ripeness. There should be a bald spot that is a particular color.

If the bald spot is yellow, then it’s ready to be picked. A green or white bald spot means it needs to keep growing.

Once you’ve harvested your watermelon, it’s important to know how to store it properly so it will keep for as long as possible.
