1, look at the shape; When you buy watermelons in the supermarket, you will see that watermelons have various shapes, but we must choose oval or round watermelons when choosing. If the watermelon has a big side and a small side, or some strange shapes, it's best not to buy it, because it doesn't grow well and tastes much worse.

2. Look at the vines; Whether watermelon is fresh or not can be judged by its vines. Like the two watermelons in the picture, one vine has disappeared and the other vine has completely withered. Both watermelons have been picked for a long time, and they are not fresh. We should choose bright green melon vines, and it is better to bend them slightly, so that watermelons will grow better and taste better.

3, look at the color; The color of watermelon is also more important, so be sure to choose a watermelon with clear texture. When choosing watermelon, you will also find a yellow area on the watermelon, which is the dark side of watermelon, that is, the place where the sun can't shine. When choosing watermelons, choose watermelons with small dark edges, which will receive more sunshine, grow better and taste sweeter.
