Reasons to plant
Native to Central Texas, Texas live oak is extremely heat tolerant. It also adapts well to various soil types in North Central Texas. Large varieties offer deep shade.
Texas live oaks grow well from the seed (acorn) if allowed to germinate in moist, warm soil. Seed development is vulnerable to insects, animals, and birds.
Texas live oaks prefer rocky, well-drained soil, and can be difficult to maintain in an environment of overly-watered turf grass. Pests include insect galls. But the galls are harmless. They require regular pruning and must be monitored for oak wilt. Oak wilt is a fungus that has killed millions of oak trees in Texas.
