Use an Airtight Container Place cut watermelon in an airtight container to lock in moisture and keep it fresh. It also prevents it from absorbing fridge odors.
Refrigerate Immediately Once the watermelon is cut, refrigerate it right away to slow down spoilage and maintain its juicy texture.
Wrap with Plastic Film If you don’t have a container, wrap large pieces of watermelon tightly with plastic wrap to minimize air exposure.
Store at 40°F or Below Keep cut watermelon at or below 40°F in the fridge to preserve its flavor and prevent bacterial growth.
Keep It Away from Ethylene-Producing Fruits Avoid storing watermelon near fruits like apples or bananas, which emit ethylene gas that can make the watermelon spoil faster.
Eat Within 3-4 Days Cut watermelon is best consumed within 3-4 days. After this, it may lose its freshness and taste.
Freeze for Long-Term Storage For extended storage, freeze the watermelon by cutting it into cubes and placing it in a single layer on a baking sheet before transferring it to a freezer bag.
