Live oak trees (Quercus virginiana) are a true Texas treasure. Their sprawling branches and evergreen leaves make them a stunning centerpiece in any yard. But like any living thing, they need a little care to stay healthy and strong.
Fall and Seasonal Care for Live Oaks
Pruning:
Late fall through early winter is the best time to prune live oaks. Doing it during the dormant season helps reduce the risk of spreading oak wilt, a dangerous fungal disease carried by beetles.
Watering:
Live oaks love deep, slow watering. Make sure the water reaches the roots, especially during dry spells, to help the tree build strong, healthy roots.
Mulching:
A 2-3 inch layer of mulch around the base of the tree can work wonders. It keeps the soil moist, protects roots, and prevents grass or weeds from competing for nutrients.
Protecting Your Tree from Disease
North Texas live oaks can face several threats:
- Oak Wilt: A deadly fungus that spreads through roots and beetles, blocking water flow in the tree.
- Hypoxylon Canker: Targets stressed trees, causing bark lesions and dieback.
- Anthracnose: Leads to leaf spots and early leaf drop, especially during wet springs.
- Root Rot: Fungi like Armillaria can decay roots, weakening the tree.
