The calendar matters more than the technique

If you take one thing from this page: do not prune oaks in North Texas between February and June.

That is the period when the sap-feeding beetles that carry oak wilt are most active, and a fresh pruning wound on an oak is exactly what they are looking for. Denton County is oak country — post oak, live oak, red oak — and oak wilt spreads not only above ground by beetle but below ground through the grafted root systems that connect neighbouring oaks. One infected tree can take others with it.

The rules that follow from that:

  • Schedule oak work outside February to June wherever the situation allows.
  • Paint every oak wound immediately, year-round. Not just in season, and not just the big cuts.
  • If storm damage forces a cut during the risk window, it gets sealed on the spot as part of proper protocol.

A crew that turns up in April with a chainsaw and no paint is a crew that has not worked in Texas long.

What good trimming is actually for

Trimming is not about making a tree smaller. It is about structure, health and clearance:

Crown cleaning — removing deadwood, crossing branches, broken and diseased material. The baseline maintenance every mature tree needs periodically.

Crown raising — lifting the lower canopy off the roof, the driveway, the walkway. A handful of significant cuts, usually the most immediately noticeable.

Crown thinning — selectively reducing interior density so light and wind pass through. This is the labour-intensive one: many small, deliberate cuts spread through the canopy. It is also what makes a mature tree look cared for rather than cut back.

Structural pruning on young trees — the highest-value work nobody asks for. A few correct cuts on a young tree prevents the weak unions and co-dominant stems that become expensive problems in twenty years.

Shrub and hedge work — shaping, rejuvenation on overgrown material, and cutting back to restore lines.

Local rules that catch people out

Tree ordinances in this service area are real and they have teeth.

Flower Mound requires a removal permit for protected trees. The process can involve a tree survey, mitigation or replacement planting, and Council review for specimen trees — and post oaks are held to a lower specimen threshold than most species, meaning a post oak becomes “specimen” at a smaller size than you would expect.

Argyle likewise requires a permit to remove a protected tree, with a site plan showing exact location, caliper, height and species. Argyle is also a Tree City USA community, and the town has been running a rebate that pays residents back for planting qualifying trees — worth knowing before you remove one.

Requirements differ between towns and get amended. We confirm what applies at your address before anything comes down.

Argyle is a post oak town, measurably

The Town of Argyle commissioned an urban forest study that surveyed fifty field plots. It found post oak making up around thirty percent of the town’s tree population and accounting for the largest single share of its tree value — hundreds of millions of dollars’ worth by the study’s own valuation.

That matters practically because post oaks are unforgiving. They resent root-zone disturbance, soil compaction, grade change and overwatering. A large share of post oak decline around here is not disease at all — it is a driveway extension, a raised bed, or an irrigation zone that was installed with good intentions inside the root zone.

If you have mature post oaks, the most valuable thing we can do is often to advise on what not to do near them.

The other regional problem: iron chlorosis

Yellowing leaves with green veins on an otherwise healthy-looking tree usually means iron chlorosis. It is widespread here because alkaline Blackland clay locks up iron and makes it unavailable to the roots — so the iron is present in the soil, the tree just cannot get at it. Red oaks and pin oaks planted in this region are especially prone. Treatment is available and it is not exotic.

Common Questions

Questions We Get About This Work

When should oaks be pruned in North Texas?

Not between February and June. That is the high-risk window for oak wilt, when the beetles that spread the fungus are active and a fresh cut is an open invitation. Outside that window is far safer, and any oak wound made at any time of year should be painted immediately — a step crews from outside Texas routinely skip. If an oak has to be cut during the risk window because of storm damage or a genuine hazard, it can be done, with sealing protocol, and it costs more for good reason.

What is oak wilt and how worried should I be?

It is a fungal disease that spreads between oaks both above ground via beetles and below ground through connected root systems, and it kills. Denton County is oak country, so it is a real regional risk rather than a theoretical one. The Argyle urban forest study put oak wilt exposure at a meaningful share of the town tree population by value. Treatment exists — macro-infusion, which runs into the high hundreds or low thousands per tree — but it is a save, not a cure. Pruning at the right time of year is far cheaper than treating.

Do I need a permit to remove a tree?

Possibly, and this surprises people who assume a tree on their own property is entirely their business. Flower Mound requires a permit for protected trees, with a tree survey, mitigation or replacement requirements, and Council-level review for specimen trees — with post oaks held to a lower specimen threshold than most species. Argyle also requires a permit for protected trees, with a site plan showing caliper, height and species. Rules differ by city and change; we check before anything is cut.

What is the difference between thinning and raising?

Crown cleaning removes deadwood, crossing limbs and broken material — the baseline. Crown raising lifts the canopy off a roof, drive or walkway, which is a small number of large cuts. Crown thinning selectively reduces interior density to let light and wind through, which is many small precise cuts throughout the canopy and is the most labour-intensive of the three. They are different jobs at different prices, and a quote that just says "trim" is not telling you which one you are getting.

Is haul-off included?

In ours, yes. It is worth asking every bidder, because debris removal is not consistently priced as a separate line and that is a common way two quotes end up looking different for the same work.

Can you top my tree to make it smaller?

We will not. Topping — cutting main limbs back to stubs — is genuinely damaging: it triggers weak regrowth, opens large wounds that decay, and permanently compromises the structure. If a tree is too large for its location the honest answers are proper reduction pruning, or removal and replanting something appropriate. Anybody who agrees to top a healthy tree is taking your money to shorten its life.
