Wikipedia Abstract

Quercus rubra, commonly called northern red oak, or champion oak, (syn. Quercus borealis), is an oak in the red oak group (Quercus section Lobatae). It is a native of North America, in the eastern and central United States and southeast and south-central Canada. It grows from the north end of the Great Lakes, east to Nova Scotia, south as far as Georgia, Alabama, and Louisiana, and west to Oklahoma, Kansas, Nebraska, and Minnesota. It has been introduced to small areas in Western Europe, where it can frequently be seen cultivated in gardens and parks. It prefers good soil that is slightly acidic. Often simply called red oak, northern red oak is so named to distinguish it from southern red oak (Q. falcata), also known as the Spanish oak. It is also the state tree of New Jersey and the provi

Usage [3]  A mulch of the leaves repels slugs, grubs etc, though fresh leaves should not be used as these can inhibit plant growth; 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; Tannin is obtained from the bark; A reddish-brown dye can be obtained from the bark; Wood - coarse-grained, hard, strong, heavy, not durable; It weighs 41lb per cubic foot; An important lumber source in America, it is highly valued for flooring, furniture, veneer, construction etc;
