Bur Oaks are hardy oak trees that are native to this area of Texas. Bur Oaks have a very long life span and, once established, can live over 150 years. They are not only drought tolerant, but also thrive in soils that are alkaline, acidic, loam, clay and areas with poor drainage. The tree’s unique characteristics include large, dark, curvy leaves; a corky, rough bark; and large, ping-pong-ball-sized acorns. As one of the white oak variety, they are very fire resistant. In the fall, the leaves turn copper and yellow in color. The leaves are quite large and can grow to 8”-12” in length. The Bur Oak’s majestic limb structure makes it one of the premier shade trees in North Texas. The canopy is dense, round and spreading. Little pruning is necessary to allow it to thrive and strengthen. With a deep root system and a tap root that can reach 14’ by the time they have reached maturity, Bur Oaks can be difficult to transplant. Additionally, their roots are rarely a problem for sidewalks, curbs and foundations. While they may have a variety of insects from time to time, they are rarely a serious threat and can be managed with horticultural sprays. Their acorns of up to 1” long or more are the largest of any oak in North America and are very desirable to wildlife in the area. Bur Oaks have been measured as tall as 75’ with an 80” diameter trunk and a canopy stretching over 100’.
