The plant is self fertile. Interestingly, the male and female flower parts are found on different flowers. Both flower sexes are found on the same tree which allows for the self-fertility. Very adaptable to soils and pH variables. Likes moisture.
Best grown in USDA zones 5 through 8, black mulberry prefers warm, moist, well-drained soil. Keep the tree watered regularly, especially during dry spells. Water well beyond the canopy to keep the roots moist and avoid premature fruit drop. As with other mulberry species, stake young trees to keep them stable until the trunk is strong enough to support the canopy. Black mulberry can grow in highly acidic to highly alkaline soils and will grow in loamy, sandy or clay soils. Choose a planting site that gets full to partial sun. Avoid planting where fruit drops might stain cars or other items.
A delicious slightly acid flavor, it makes an excellent dessert fruit. The fruit is juicy and refreshing, though it must be used as soon as it is ripe (from mid-August to September) otherwise it will start to rot. The fruit falls from the tree as soon as it is fully ripe. It is best, therefore, to grow the tree in short grass to cushion the fall of the fruit but to still make it possible to find and harvest. The fruit can also be dried and ground into a powder. The fruit is up to 1 inch in diameter. There is a wealth of recipes available for these delicious berries. Mulberry wine included.
