Black Diamond is an heirloom, open-pollinated variety of watermelon. For generations, Black Diamond watermelons have been a popular choice for both commercial and home growers for many reasons. Black Diamond watermelon plants produce vigorous vines, which often yield fruits weighing in excess of 50 lbs. Due to the large size of fruits, gardeners can expect this plant to require a long growing season in order to harvest fully ripe melons. Mature melons have very hard rinds and sweet, pink-red flesh. Growing Black Diamond watermelon plants is very similar to growing other varieties. Since all watermelon plants thrive in sunny locations, at least 6-8 hours of sun each day is imperative. Additionally, those wishing to plant Black Diamond will need to ensure a long growing season, as this variety may take at least 90 days to reach maturity.
