Oak Wilt FAQ
What is oak wilt and why does the POA care about it?
Oak wilt is a fungal disease that kills oak trees. It spreads tree to tree through connected root systems and by sap-feeding beetles that carry spores to fresh cuts. Live oaks, the most common oak in our neighborhood, share root systems, so one infected tree can kill its neighbors. An outbreak affects the whole community, not just one lot.

When can I trim my oak trees?
Avoid pruning oaks from February 1 through June 30. This is when the beetles that spread the fungus are most active. The safest windows are the coldest part of winter and the hottest part of summer.

Do I really need to paint pruning cuts?
Yes. Paint every cut or wound on an oak immediately, within minutes, not hours. Any latex or wound paint works. This applies year-round, and it applies to accidental damage too, like a mower or equipment scrape.

Does this apply to storm damage?
Yes. If a limb breaks in a storm, paint the wound as soon as it's safe to do so.

Can I bring in firewood?
Be careful with oak firewood from unknown sources. Infected red oak logs can carry fungal mats that spread spores. If you buy oak firewood, make sure it's well seasoned (dried at least one full year), and never stack unseasoned oak near healthy trees.

What are the signs of oak wilt?
In live oaks, look for leaves with yellow or brown veins while the rest of the leaf stays green (called veinal necrosis). Red oaks often wilt quickly and drop leaves that turn brown from the outer edge inward. Rapid canopy thinning or a tree dying within weeks is a red flag.

What do I do if I suspect oak wilt on my property or a neighbor's?
Report it. Email the POA at poaskyline@gmail.com and consider a site visit from a Texas A&M Forest Service regional forester or an ISA-certified arborist with oak wilt experience. Early detection matters because trenching between root systems can stop the spread.

Does hiring a tree company get me off the hook?
No. Ask any crew working on your property whether they sanitize their equipment between jobs and paint cuts immediately. Some crews don't follow oak wilt protocols. You're responsible for what happens on your lot.
