Oak galls are excrescences that are sometimes produced in great numbers on the tree and are caused by the activity of the larvae of different insects. The insects live inside these galls, obtaining their nutrient therein. When the insect pupates and leaves, the gall can be used as a rich source of tannin, that can also be used as a dyestuff. The bark has been boiled with hemlock (Tsuga sp.?) and soft maple bark (Acer spp), and the liquid used to remove rust. he mixture was also believed to prevent rust.Wood - close-grained, strong, hard, tough, heavy. It weighs 48lb per cubic foot. Trees do not self-prune and dead branches remain on the trees for many years. This does mean that the wood is usually quite knotty. The wood is of some importance commercially, it is used for construction, furniture, interior finishes etc, as well as for fencing and fuel.

Prefers warmer summers than are usually experienced in Britain, trees often grow poorly in this country and fail to properly ripen their wood resulting in frost damage overwinter. A relatively fast-growing tree in the wild, living 300 - 350 years, though it is relatively shallow-rooted and is considerably more susceptible to forest fires than most other oaks. This species is one of the best of the white oaks for growing in this country. However, it is said that the seed is rarely formed in Britain. The tree flowers on new growth produced in spring, the seed ripening in its first year. Trees do not commence bearing until about 25 - 30 years old, large crops being produced every 3 - 5 years. Intolerant of root disturbance, trees should be planted in their permanent positions whilst young. The seed of this species is attached to the tree by unusually long (by oak tree standards) stems. Hybridizes freely with other members of the genus.Plants in this genus are notably resistant to honey fungus.
