Harvest:
A ripe melon will develop a circular crack where the stem attaches to the fruit. Ripe melons will have a sweet aroma at the stem end. Ripe melons will slip easily off the stem; a half-ripe melon will require more pressure and may come off with half the stem attached. Leave melons on the vine until they are ripe.
