Oak Wilt: Austin's Biggest Tree Threat
Oak wilt has killed tens of thousands of live oaks across Central Texas. Austin sits in the epicenter. If you have live oaks on your property, this section is required reading.
Oak Wilt Prevention Rules
- • Never prune oaks February 1 – June 30. Sap beetles are active and spread the fungus through fresh wounds.
- • Paint all oak wounds immediately — even storm damage. Use pruning sealer or latex paint. This blocks beetle access.
- • Sanitize tools between trees. The fungus transfers on dirty equipment. Use 10% bleach or Lysol.
- • Don't move firewood from infected areas. The fungus lives in dead wood and spreads when transported.
- • Watch for symptoms: veinal necrosis (brown patterns following leaf veins), rapid leaf drop, dead branches.
Propiconazole injection ($200–$500/tree) can protect healthy oaks near infected trees. It's not a cure — it's a preventive treatment that buys 2–3 years of protection. If you spot oak wilt symptoms, call a certified arborist immediately. Early trench barriers ($3,000–$10,000) can stop the underground root-graft spread to nearby oaks.
Austin's Heritage Tree Rules
The City of Austin protects large trees through its Land Development Code. Here's what you need to know:
| Category | Trunk Diameter | Permit Required? | Notes |
|---|---|---|---|
| Protected Tree | 8–19 inches | Yes, for removal | Mitigation may apply |
| Heritage Tree | 19+ inches | Yes, strict review | Denial possible, replacement trees required |
| Small Tree | Under 8 inches | No | Free to remove |
Trunk diameter is measured at 4.5 feet above ground (DBH — diameter at breast height). Your arborist handles the permit application and will tell you if your tree qualifies for removal. The process takes 2–4 weeks. Removing a heritage tree without a permit carries fines of $500–$10,000.
Common Austin Trees & Their Needs
Live Oak
Austin's signature tree. Trim July–January only. Watch for oak wilt. Mature specimens are almost always heritage trees. Never top. Structural pruning every 3–5 years.
Pecan
Texas state tree. Heavy nut production creates debris. Trim dead wood annually. Susceptible to pecan scab in wet years. Large specimens need professional care.
Cedar Elm
Native, drought-tough and fast growing. Needs structural pruning when young to prevent weak branch unions. Handles Austin's alkaline soil better than any other large shade tree.
Crape Myrtle
Don't commit crape murder. Light pruning of seed pods, suckers and crossing branches. Never cut back to stubs. If it's too big, replace it with a smaller variety instead of hacking it annually.
Tree Service Questions — Austin, TX
What is oak wilt and why does it matter in Austin?
Oak wilt is a fungal disease that kills live oaks — Austin's most iconic shade trees. It spreads two ways: through root grafts between nearby oaks (underground) and through sap-feeding beetles that visit fresh pruning wounds (above ground). Once a tree is infected, it can die within weeks. There's no cure, only prevention and containment. Austin has lost thousands of live oaks to this disease. That's why the February–June pruning ban exists.
Does Austin require a permit to remove trees?
Yes, for protected trees. Any tree with a trunk diameter of 19 inches or more (measured 4.5 ft above ground) is a "heritage tree" requiring a City of Austin permit before removal. The permit costs $50–$200 and takes 2–4 weeks. If approved, you may need to plant replacement trees (mitigation). Removing a heritage tree without a permit carries fines of $500–$10,000 per violation. Your arborist should handle the permit process.
How often should I trim my trees in Austin?
Every 3–5 years for healthy mature trees. Young trees benefit from structural pruning every 1–2 years to establish good branch architecture. Dead or hazardous limbs should be removed immediately regardless of season (even oaks — but paint the wound during oak wilt season). After major storms, schedule an inspection to check for hidden damage. Don't wait until a weakened limb falls on your roof.
Should I hire an arborist or a tree trimmer?
For mature live oaks, heritage trees or anything near power lines — hire an ISA-certified arborist. They understand tree biology, disease management and proper pruning techniques. For small ornamental trees and crape myrtles, a general tree trimmer is fine. Never hire anyone who recommends topping a tree (cutting the top off). That's hack work that damages the tree permanently. A good arborist costs 20–30% more but protects your investment.
What about crape myrtle pruning in Austin?
Don't commit "crape murder" — the ugly practice of cutting crape myrtles down to stumps every winter. It produces weak, thin growth and ruins the tree's natural shape. Proper crape myrtle pruning removes seed pods, crossing branches and suckers at the base. Light thinning, not butchering. If your crape myrtle is too big for its space, replace it with a smaller variety — don't hack it down annually.
