QUESTION: How can you tell when a watermelon is ready to harvest?
It’s tempting to cut that beautiful watermelon from the vine as soon as it looks like it’s big enough, but size is not the only clue to ripeness. Before you cut the melon from the vine, turn it over and note the color of the ground spot – where the melon rests on the ground. The spot should be creamy yellow. If it’s white, the watermelon is not ripe enough to cut.
A tendril grows at the end of the watermelon. If it’s still green, wait a few more days before you harvest. If it is half-dead, it’s likely the melon is ripe. The age-old method of giving the fruit a thump may also work; a ripe watermelon sounds hollow when you thump it.
Cantaloupes and other small melons don’t have the tendril or a significant soil spot, like watermelons, but there are other clues to gauge its ripeness. Cantaloupes develop a golden color under the netted rinds when the melon is ripe. They also soften at the end opposite the stem when they ripen, which you can feel if you press gently. Ripe cantaloupes also have a sweet fragrance, and the melon will separate easily from the vine.
