Yellow Crimson and Crimson Sweet watermelons are very similar, but have subtle differences. Beyond the color of the flesh being yellow instead of the traditional red, yellow crimson watermelons have a honey or apricot-like sweetness.

Giving water at the right time is what makes a melon sweet.
While they’re growing, watermelons will need a lot of water. However, too much water can dilute the flavor. So when it’s almost time to harvest, decrease the amount of water. The last week before harvesting, you can stop watering.

If you tap on it, a ripe watermelon will have a hollow sound. This method can take some practice and careful listening. When growing your own watermelon, checking the tendrils can be a more successful indicator. When the tendril closest to the melon withers and turns brown, the melon is ripe.

Select a fully ripe watermelon to save seeds from. Slice the watermelon open and remove the large dark seeds from the yellow flesh. Wash the seeds, then lay them out for about a week until the seeds are completely dry. Store the seeds in a cool, dry location to plant again.
