Frequently Asked Questions

What does a certified arborist do that a regular tree service doesn't?
A certified arborist has completed ISA-accredited training in tree biology, soil science, pest and disease identification, and proper pruning techniques. They can diagnose health issues, recommend treatments, and perform pruning in ways that protect the tree's long-term structure, rather than just cutting for clearance or aesthetics.
Can an arborist help save a tree that looks like it's dying?
In many cases, yes. Dying appearances can result from treatable conditions like nutrient deficiencies, soil compaction, fungal infections, or pest damage that an arborist can identify and address. The sooner you get a professional assessment, the better the chances of an effective intervention.
How do I know if my Denver tree has bark beetles or another pest problem?
Signs include pitch tubes or resin on the bark, small entry holes, yellowing or browning needles on conifers, and D-shaped exit holes associated with emerald ash borer. A certified arborist can confirm the pest, assess the extent of damage, and recommend treatment options while there's still time to act.
Is it worth paying more for a certified arborist versus a standard tree crew?
For straightforward removal of a dead or hazardous tree, a qualified tree service crew often does the job just fine. But for health assessments, disease treatment, or pruning on valuable or mature trees, the expertise of a certified arborist can prevent costly mistakes and extend the life of trees you want to keep.
What are the most common tree diseases affecting Denver properties?
Cytospora canker on spruces, fire blight on fruit and ornamental trees, and various root rot fungi are among the more common problems Denver arborists encounter. Drought stress also weakens trees and makes them more vulnerable to secondary infections and pest attack, which is an ongoing concern along the Front Range.
Do arborists offer tree cabling or bracing for structurally weak trees?
Yes, cabling and bracing are established arboricultural techniques used to support trees with split trunks, heavy co-dominant leaders, or other structural vulnerabilities. It's often a viable alternative to removing a tree that's otherwise healthy but has a mechanical weakness that poses some risk.
