Tree trimming and pruning in Greeley, CO

Pruning done for a reason

Good pruning starts with a question: what is this cut supposed to achieve? In Greeley there are usually four answers.

Crown thinning for wind

This is the one that matters most here. Greeley sits in open plains country with almost no natural windbreak, and chinook events regularly push 60 to 80 mph down off the foothills. A tree carrying a dense, unthinned crown catches that wind like a sail, and the failure point is usually a weak union it has carried for years.

Selectively removing interior branches lets wind pass through rather than push against the canopy. Done properly it takes out no more than a fifth of the live crown in a season and leaves the tree looking untouched from the street.

Deadwood removal

Dead limbs come out whenever they are found. They are the pieces most likely to drop without warning, and they are also the entry point for decay organisms into the living wood.

Clearance

Branches rubbing shingles, blocking a driveway sightline, growing into a service drop or hanging over a neighbour's fence. Straightforward work, but worth doing before the branch does damage rather than after.

Structural pruning on young trees

The cheapest tree work you will ever buy. Correcting a competing leader or a narrow, included-bark union on a ten-year-old tree takes twenty minutes. Dealing with the same defect on a forty-year-old tree means a crane, or a removal.

When to prune in Northern Colorado

Late winter through early spring — roughly February to early April — is best for most species. The tree is dormant, its architecture is visible without leaves, and cuts close before insects become active.

Two exceptions worth knowing. Elms and oaks have timing restrictions to avoid attracting the beetles that spread Dutch elm disease and oak wilt, so those get pruned in the dormant season only. And anything hazardous — a cracked limb, storm damage, a branch resting on the roof — is dealt with immediately regardless of the calendar.

How we cut

Every cut is made just outside the branch collar — the slightly raised ring where the branch meets the stem. That collar contains the tissue the tree uses to seal the wound. Cutting flush to the trunk removes it and leaves a wound the tree cannot close properly. It is a small detail and it is the clearest sign of whether the person on your property knows the trade.

We do not paint or seal cuts. Wound dressings were standard practice for decades and the research has been clear for a long time that they trap moisture and slow the tree's own compartmentalisation.

Questions we get about this

How often should trees be pruned?

Young trees benefit from a light structural prune every two to three years. Mature trees typically need attention every three to five years, sooner if they are large, dense, or sit over a house. Deadwood can be removed any time it appears.

Will thinning hurt the tree?

Not if it is done in proportion. Removing up to about a fifth of the live crown in a season is well within what a healthy mature tree tolerates. Problems come from over-thinning, lion-tailing, and topping.

Can you prune around power lines?

Only outside the 10-foot zone around energised lines. Very few tree services are authorised to work closer than that. If branches are contacting a line, call Xcel Energy, who handle utility line clearance.

My tree looks too big for the yard. Can you just cut the top off?

No, and no reputable arborist will. Topping produces weak regrowth and large wounds that never close, leaving you with a more dangerous tree. A proper crown reduction can take some height off while keeping the structure sound, or the tree can be removed and replaced with a species that fits.

Do you clean up the branches?

Yes, included. Brush is chipped and hauled, the area is raked, and we leave the site clean.
