In the summer, to choose a naturally sweet ripe watermelon, you don't need to tap it; just look at one specific spot and you can tell right away.

How to choose a naturally sweet ripe watermelon:

1. Look at the spot on the bottom of the watermelon:

   • Location: This is the area where the watermelon touches the ground as it grows. A ripe watermelon will have a yellow or light orange color on this spot. This indicates that the watermelon has ripened naturally and will be sweet. If this area is green, it suggests that the watermelon hasn't fully ripened and may not be sweet.

2. Feel the watermelon’s skin:

   • Touch: A naturally sweet watermelon will have a slightly firm and taut skin, without deep dents or mushiness. When you gently press on the skin, it should not feel overly soft, indicating that the watermelon has matured and ripened properly.

3. Check the shape of the watermelon:

   • Shape: A ripe watermelon typically has a round and even shape, without any irregularities or bumps. A well-balanced watermelon, with a good proportion between length and width, generally indicates better quality and ripeness.

Tips when choosing a watermelon:

• Avoid selecting watermelons with overly shiny skins, as this could be a sign of chemical treatment.

• Opt for a watermelon that is medium-sized, not too large, as large watermelons typically contain less sugar and may not be as high in quality as medium-sized ones.

Conclusion:

To choose a naturally sweet watermelon, simply pay attention to the color of the spot on the bottom, check the tautness of the skin, and select a well-proportioned fruit. These are simple tips that will help you buy a sweet and delicious watermelon without needing to tap it.
