Look for color.

Of course, the exterior of a watermelon should appear mostly green—but green isn't the only color to consider when on the hunt for the best watermelon at the grocery store. One way to ensure you're picking a watermelon that's ripe and ready to serve is to examine the yellowish spot on its rind.

Known as the watermelon underbelly or ground spot, this coloring inconsistency occurs on the underside of watermelons due to their former positioning while still growing on the vine. Receiving the least amount of sunlight, the yellow pigmentation develops on the side of the watermelon that had direct contact with the ground.

"The underbelly, or ground spot, should not be orange," says Manaker. Elaborating further, she explains that a watermelon is likely overripe if the underbelly looks sunflower yellow or nearly orange. If its ground spot appears too light or even white, the watermelon might be underripe—and if so, will probably taste more like a cucumber. "Butter yellow is ideal."

Location is key.

When shopping for watermelon at the grocery store, you should take note of where the watermelons are located within the produce department.

"Watermelon is a hydrating fruit that is loaded with key nutrients and has a natural sweetness with no added sugar," says Manaker. "When shopping for watermelon, one tip is to make sure your melon isn't housed near the bananas at the store."

Why? According to Manaker, bananas emit an ethylene gas that can cause the watermelons to spoil more quickly. It's also important to make sure there is some distance between your watermelon and any ethylene-emitting produce you might have when storing your fruit at home.

"Make sure you keep your watermelon away from bananas once you're home, too," says Manaker.

Don't focus on the pattern.

Rumor has it that there is a correlation between watermelon ripeness and the stripes that appear on the watermelon's rind. However, Manaker explains that this is simply untrue.

"Despite what you may hear on social media, striping is not an indicator of ripeness," says Manaker. "The reality is, some watermelon varieties don't even have stripes, and others naturally contain thick ones."

No matter how the external pattern appears, you can always enjoy a whole watermelon in its entirety.

"Remember that the entire watermelon is edible," advises Manaker. "The juice, seeds, and even rind can be enjoyed, making it a sustainable choice."

Don't rely on stems.

While a dried watermelon stem can indicate ripeness, a green one might mean you have a watermelon that was prematurely cut from the vine. But contrary to popular belief, watermelon stems do not always comes off the vine with the fruit when they are first harvested.

"Some people say to look for a dried stem, but not all watermelons are cut with excess stem even showing," explains Manaker.

A particularly labor-intensive task, watermelon harvesters known as "cutters" inspect each melon's color and size to ensure quality and ripeness prior to removing them from the vine.

"So, that [method] is a favorite of a particular farmer—not something we can use at the store," says Manaker.

Mother Nature may still have her own agenda.

As much as you can prepare to take home the best watermelon, this mysterious melon may still fool you. So, don't beat yourself up if after trying every trick to pick the best watermelon, you still end up stuck with a lemon.

"Even if you follow all of the rules for picking the best watermelon, on occasion, Mother Nature can trick you," says Manaker. "You can still be stuck with a less-than-ideal watermelon, even if it checks all of the 'best' boxes."
