Winter is when most pruning here should happen. Structure is visible without leaves, plants are dormant, and for oaks it is the only genuinely safe window.
Oaks: this is the window
The Texas A&M Forest Service asks homeowners to avoid pruning oaks from February through June because that is when the beetles spreading oak wilt are most active. Late fall through January is the safe stretch.

Paint every oak wound immediately regardless of month. If your oaks need work, this is the season to schedule it rather than waiting until they look untidy in spring.
What benefits from a winter cut
Deciduous shade trees, for structure and deadwood removal. Fruit trees, for shape and productivity. Roses, cut back hard in late winter before spring growth. Ornamental grasses, cut to a few inches before new growth appears, which is also when muhly and other grasses stop looking good.
Summer-flowering shrubs that bloom on new wood can be pruned now. Spring bloomers cannot, and that is where people go wrong.
What to leave alone
Spring-flowering shrubs and trees set their buds the previous year. Pruning them in winter removes the flowers you were waiting for. Redbuds, Texas mountain laurel and spring-blooming spirea should be pruned right after they finish blooming, not before.
Tender plants damaged by a freeze should also be left until the risk of further freezes has passed. That brown material is insulation, and cutting it early exposes what is alive underneath.
Never top a tree
Cutting a canopy back to stubs, including the crape myrtle version done every winter across Central Texas, forces weak regrowth, invites decay and permanently ruins structure. A properly pruned crape myrtle needs very little: remove suckers, crossing branches and deadwood.
The general rule is to remove no more than about a quarter of the canopy in one season, and to cut just outside the branch collar so the tree can seal the wound. Anything more aggressive is stress the tree pays for later. See tree care if the work is beyond ladder height.
Tools and cuts
Bypass pruners for anything up to about half an inch, loppers to an inch and a half, a pruning saw beyond that. Anvil pruners crush stems rather than slicing and should be left for deadwood.
Clean cuts matter because the plant seals a clean wound far faster than a torn one. Sharpen before the season and clean blades between plants if you are cutting anything diseased, since pruners spread problems efficiently.
Cut just outside the branch collar, the slightly swollen ring where a branch meets the trunk. Cutting flush removes the tissue the tree uses to seal, and leaving a long stub gives decay somewhere to start.
How much to remove
The working limit is about a quarter of the canopy in one season, and less on a stressed or mature tree. Removing more forces a flush of weak growth that costs the tree energy it needed for roots.
Shrubs tolerate harder cutting. Many Central Texas natives, including salvias, lantana and rock rose, respond well to being cut back substantially in late winter, and they come back denser for it.
The exception is anything already stressed by drought. A tree that struggled through a hot summer should be pruned lightly if at all, because it needs its leaf area to rebuild reserves.
The crape myrtle problem
Every winter across Central Texas crape myrtles get topped to stubs. It is so widespread that people assume it is correct. It is not, and it permanently damages the tree.
Topping forces weak shoots from the cut points, which are poorly attached and break in storms. It ruins the natural vase shape and the smooth exfoliating bark that is the main reason to plant the tree.
Correct crape myrtle pruning is minimal: remove suckers at the base, crossing branches, and deadwood. Thin the interior lightly if it is congested. That is the entire job, and a properly grown crape myrtle needs almost nothing else for decades.
Common questions we get about this
Three come up almost every time.
Can I do this myself? Usually part of it. The diagnostic work and the finishing details are where experience shows, and the preparation underneath is where shortcuts cost the most. Most homeowners who do it themselves succeed on the visible work and struggle with base preparation, drainage and timing.
When is the best time? In Central Texas, almost always autumn. Soil is still warm, air has cooled, and anything planted or installed has months to settle before summer stress arrives. Spring works but races the heat.
What does it cost? Any number quoted without seeing the property is a guess, because our two soils, the slope and the access change the work substantially within a few miles. What we can say is that the invisible preparation is where the real cost sits, and where the cheapest bid has usually economized.
