Tree Care Resources
Trees do not always make it obvious when something is wrong. A thinning canopy, broken branch, unusual leaf color, insect activity, storm damage, or declining growth can have several possible causes.
The Tree Pros resource library is here to help Denver-area property owners understand what they are seeing, what may require attention, and when it makes sense to call a Certified Arborist. Our guides are based on decades of professional tree care experience and the conditions trees face along Colorado's Front Range.
What Are You Seeing?
Start with what you are seeing and follow the path to the right Tree Pros service.
Learn about canopy thinning, discoloration, dead branches, unusual growth, drought stress, disease symptoms, and other signs of decline.
Learn what to look for after heavy snow, wind, or severe weather and when tree damage may require immediate professional attention.
Learn when pruning helps, what proper pruning should accomplish, and why removing more branches is not always better.
Learn what arborists consider when deciding whether a tree can be preserved or whether removal is the practical option.
Learn about insect symptoms, bark problems, canopy decline, and common pest concerns affecting trees in the Denver metro.
Some tree problems are difficult to diagnose from symptoms alone. An arborist evaluation can help identify what is happening before treatment or removal is considered.

Local Tree Knowledge
Tree care in Denver comes with its own set of challenges. Dry air, periods of drought, compacted urban soils, heavy spring snow, strong winds, rapid weather changes, insects, disease, and mature trees growing close to homes and streets can all affect tree health and structure.
The purpose of these resources is to explain those issues in plain language so property owners can recognize potential problems earlier and make better decisions about their trees.
Tree Pros has served the Denver metro since 2003, and founder Paul Goin has worked professionally in tree care since 1981. Our educational content reflects that experience without turning every article into a sales pitch.
