Oak WIlt

Oak Wilt is one of the most destructive tree diseases in Texas. It’s caused by a fungus that cuts off the flow of water inside the tree, and once it takes hold, it spreads quickly through connected root systems and by beetles attracted to fresh wounds. You’ll often see the top of the canopy turn brown or bronze first, while the rest of the tree looks fine. Then, within weeks, entire sections start dying off.

Live oaks and red oaks are especially at risk, and once the fungus spreads through roots, it can move from one tree to the next like wildfire. That’s why catching it early is critical. Infected trees can’t usually be saved, but surrounding ones can if the disease is stopped in time.

Professional root trenching, proper pruning timing, and disease management are key to keeping oak wilt from spreading. If you notice your oak’s leaves browning early or one side of the canopy thinning out, it’s time to get an inspection before it spreads to others on your property.
