When Is the Best Time to Trim Live Oaks in the Coastal Bend?
By M&S Tree Service · Portland, TX
Live oaks are the signature tree of the Coastal Bend. They're in nearly every front yard from Portland to Calallen, and sooner or later most of them need a trim: limbs on the roof, branches scraping the truck in the driveway, dead wood waiting for the next storm.
The short answer: avoid February through June
Texas A&M Forest Service recommends avoiding pruning oaks from February through June. Those are the months when the sap beetles that spread oak wilt are most active, and fresh cuts attract them. Oak wilt is one of the most destructive tree diseases in Texas, and live oaks are especially vulnerable because their roots grow together and the disease can spread from tree to tree underground.
The Forest Service also recommends painting every fresh wound on an oak with a wound dressing or latex paint, any time of year. It's one of the few cases where painting a cut is recommended.
What about a limb that can't wait?
Safety comes first. A cracked limb hanging over the bedroom doesn't wait for July. If an oak has to be cut during the risky months, the cuts should be painted right away.
What a good oak trim looks like
- Dead and broken limbs come out first, since they're the ones that fall in a storm.
- Limbs resting on or hanging over the roof get lifted.
- Low limbs over the driveway, sidewalk and street get raised for clearance.
- Crossing and crowded branches are thinned so wind can move through the canopy.
- The tree still looks like a live oak when it's done. No topping.
How often do live oaks need trimming?
It depends on the tree and how close it is to the house. Many homeowners have their oaks looked at every couple of years to keep the limbs off the roof. A tree out in the open with nothing under it may need very little.
