As it tolerates soils that are light to heavy, wet to dry, Common Hackberry is an ideal street tree. Urban pollution, temperature fluctuations, and heavy winds are not a problem for this tree. It can also be used as a specimen plant, in a tree border, or to naturalize an open space.
The fruit is eaten by many animals, including Wild Turkey, Cedar Waxwings, Mockingbirds, Robins, and more.
Common Hackberry should be pruned by a trained arborist every 7-10 years for structure. Deformed branches (Witches Broom) can be removed if they are unsightly. As with all trees, maintaining a good mulch ring around the base will maintain good vigor.
We invite you to check out the Arborist For Hire lookup at the Wisconsin Arborist Association website to find an ISA Certified Arborist near you.
Common Hackberry often gets nipple gall, a deformed growth on the leaves caused by insects. This is a purely cosmetic issue and should be considered an ornamental disease.
Witches Broom, a deformity in new twig growth, is caused by the Gall Mite (Eriophyes spp.) and Powdery Mildew. Like Nipple Gall, this disease may be unsightly but will not kill the tree.
Common Hackberry is classified in the same family as Hops (Humulus spp.) and Marijuana (Cannabis spp.).
Hackberry is a corruption of the Scottish word ‘Hagberry’, the name for the Bird Cherry (Prunus avium) found in Britain.
The berries of the tree are edible and ripen in early September. Both the flesh and the seed can be eaten. Timber from Common Hackberry is weak and has poor rot resistance, but is sometimes used for crates and fencing.
Common Hackberry is a great addition to a bird garden and can be combined with Serviceberry, Eastern Redcedar, Coneflowers, and Chokeberry to provide food and cover year-round.
