Whether you’re picking it off of the vine or off of a shelf at the grocery store, you’ll want to follow these tips for choosing the right watermelon. . First, pick up a watermelon that is uniform and feels heavy for its size. You want to avoid ones that have any blemishes like bumps or dents. Turn it in your hands so that you can see the “field spot“. This is the discolored part of the melon where it sat in the field. It starts off white and becomes yellowish when it’s ripe and at its full sweetness. Look for the yellow spot when picking out the watermelon. This will be a very juicy watermelon! Another tip is to look at the stem if there is one. A dry stem indicates that it’s ripe, while a green stem indicates that it wasn’t ready yet.
