Pests and Diseases
Scarlet oak is susceptible to oak wilt as well as heart rot, caused by Stereum gausapatum. Pests come primarily in the form of defoliators, but heavy infestations of the gouty oak gall wasp can cause the death of the tree.
The wood is generally marketed as red oak, but is of inferior quality, being somewhat weaker and not forming as large as a tree.
The acorns of this tree are a favorite food for gray squirrels, chipmunks, mice and birds, especially blue jays.
