🌳 It’s the Best Time to Prune Your Oak Trees!
If you’ve been thinking about trimming your oak trees, now is the ideal time. In Helotes and San Antonio, the safest window for pruning is late fall through winter, especially December and January.
🍂 Why Winter Pruning Is Best
Oaks are dormant, so pruning causes less stress.
Beetles that spread Oak Wilt are barely active.
No leaves = cleaner, safer, more accurate pruning.
🛑 What to Know About Oak Wilt
Oak Wilt is a serious fungal disease that spreads through sap-feeding beetles and connected roots. Pruning in the wrong season (especially spring) increases the risk dramatically.
🛡️ How to Prevent Oak Wilt
Stick to the Nov–Jan pruning window.
If you must prune at another time, paint every cut immediately.
Keep tools clean and disinfected.
Don’t leave cut wood piled up near other oaks.
📄Oak trimming is prohibited Feb 1–May 31 unless done by a licensed tree company following city guidelines.
🌱 When to Call a Pro
If you suspect Oak Wilt or notice unusual leaf drop, discoloration, or sudden die-off, it’s smart to get a certified arborist or professional tree service to evaluate your trees.
Bottom line: Winter is the safest and healthiest time to prune your oaks. 🌳💚
