It may be difficult to transplant because of a deep taproot. The wood is orange-yellow, hard, heavy and strong. Seldom used as a landscaping specimen, it is more suited to a woodland site. Never prune an oak tree while it has green leaves, for fear of spreading Oak Wilt, which can kill a tree in one season.
Do not prune Oaks during the growing season. Oaks are highly susceptible to Oak Wilt, which is spread by a sap beetle that is attracted to fresh wounds. Prune oaks only during the dormant season in winter after the leaves have fallen. Oak Wilt can kill a mature Oak within one season.
The common name is in reference to the colour of the bark on older trees.
Larval and foliar host for over 500 species of moths and butterflies, including duskywings and hairstreaks. Black Oak is in the Red Oak group, so the acorns are high in bitter tannins, but a preferred food nevertheless, for wild turkeys, jays, wild ducks, grouse, and of course, squirrels and chipmunks.
