Fall in Houston doesn't look like fall anywhere else. The leaves don't turn until November, if they turn at all. The temperatures stay warm well into October. And most homeowners are still running their AC when the rest of the country is raking leaves.
But even in Southeast Texas, the season shift matters for your trees — and October is actually one of the best months of the year to get ahead of things. Hurricane season starts winding down. The worst of the summer heat is behind us. And cooler soil temperatures make fall one of the best times for certain tree work, new plantings, and getting eyes on anything that took a beating this past storm season.
Here's what Houston homeowners should be thinking about for their trees this fall.
First: Do a Post-Storm-Season Walk
If you haven't done it yet, walk your property and look at your trees with fresh eyes.
2026 threw a lot at the Houston area. Between the heavy rains earlier this summer, Tropical Storm Bertha in the Gulf, and whatever else rolled through your neighborhood between June and now, your trees may be carrying damage that isn't obvious from the back porch.
What to look for:
Cracks or splits in major limbs or the trunk that weren't there before
Leaning that seems new, even a subtle shift in a large tree's angle is worth noting
Hanging or partially attached limbs, these are the ones that come down on their own, usually at the worst time
Fungal growth at the base, mushrooms or shelf fungus appearing after a wet summer is a sign of internal decay
Thinning or dying sections of canopy that may have been stressed by flooding or heat and are now showing it
Anything that catches your attention is worth a professional look before winter. The last thing you want is to head into the holidays with a compromised tree over your roof.
October and November Are the Best Months to Trim Your Oaks
This one is important and not enough Houston homeowners know it.
Live oaks and other oak species should not be trimmed between February and June; that's peak activity for the sap beetles that spread oak wilt, and fresh pruning cuts during those months are one of the primary ways the disease moves from tree to tree in Houston neighborhoods.
Fall and winter are a completely different story. Once temperatures drop and beetle activity slows, trimming oak trees is not only safe; it's ideal. The tree is putting less energy into active growth, wounds compartmentalize better, and any structural issues that developed over the summer can be addressed without the oak wilt risk that comes with spring pruning.
If your oaks need attention, deadwood removal, crown thinning, clearance from the roofline, schedule it now. By the time spring rolls around and the window closes again, you'll be glad you did.
Fall Is the Right Time to Plant New Trees
If you've been thinking about adding trees to your property, October through December is the best planting window in the Houston area. Here's why it works:
The heat stress that makes summer planting so hard on new trees is gone. Cooler temperatures and higher rainfall give new root systems the chance to establish before the following summer's heat arrives. A tree planted in October or November has six months to get rooted before it faces its first Houston summer, compared to a spring planting that might face brutal heat just eight weeks in.
Live oaks, cedar elms, shumard oaks, bald cypresses, and most native Texas species all transplant well in fall. If you've got a spot in your yard that needs a tree, now is the time to put one in.
Get Your Trees Ready Before the Holidays
This is a practical one that catches a lot of homeowners off guard.
November and December are peak demand months for tree service in Houston. Homeowners suddenly realize they have a dead tree hanging over the driveway when family is about to visit, or a storm takes something down on Thanksgiving weekend and they need emergency response with every crew in town already booked.
The homeowners who handle things in October, while schedules are still open and there's no weather urgency, get the work done on their timeline at normal rates, with their pick of appointment slots. The ones who wait until December are competing with everyone else who waited.
If you've got trees you've been meaning to have trimmed, assessed, or removed, October is genuinely the best month to make that call.
A Note on Crepe Myrtles: Don't Touch Them Yet
Every fall we get calls from homeowners who want to cut their crepe myrtles back before winter. The thinking makes sense — it's a dormant period, clean things up, start fresh in spring.
The problem is that heavy pruning on crepe myrtles in fall and early winter can stimulate new growth that gets damaged by a cold snap. The right time to prune crepe myrtles in the Houston area is late February to early March, just before new growth starts pushing. At that point you can see exactly what you're working with and make clean cuts above healthy wood.
For now, leave them alone. Deadhead the spent seed clusters if you want to clean up the appearance, but hold off on any structural cuts until late winter.
What to Do If You Lost Trees This Storm Season
If you had trees come down or had to have damaged trees removed, this fall is a good time to think about what to put back in their place.
The spot where a tree stood for decades now has established soil structure, root channels, and a microclimate shaped by years of shade and leaf drop. Replanting in that spot with a species appropriate for Houston's conditions gives a new tree a real head start.
If you want guidance on what species makes sense for a specific location on your property — sun exposure, drainage, proximity to structures, soil conditions — that's exactly the kind of conversation worth having with a professional before you go to the nursery.
