The most important task is to find a watermelon that has no cracks, bruises, or other signs of damage on its surface. Otherwise, the whole exercise will be for nothing.

You shouldn’t select a very large watermelon if you want to keep it for a long time. The most appropriate size in this case is one that weighs around 4 kg (9 lbs).

It’s also best to go for a variety of watermelon that ripens slowly and has a thick skin.

The watermelon you intend to keep for a long time shouldn’t be very ripe — they’re more likely to go off.
