Understanding Spider Mites
If you’ve ever noticed dusty, bronzed foliage on a spruce, pale speckles on leaves, or extremely fine webbing between needles or under leaves, there’s a good chance you’ve encountered spider mites. They’re one of the most common and damaging landscape pests in Colorado—and they’re tiny enough that most homeowners don’t realize they’re there until damage is already visible.

Soil Health and Organic Amendments: What Colorado Homeowners Need to Know
Most people think of tree care as pruning, watering, or fertilizing. But the truth is this:
The health of your soil is the foundation of the health of your trees. If the soil is compacted, lifeless, or low in organic matter—which is extremely common in Colorado—trees struggle no matter how much you water or fertilize.

Understanding Scale Insects in Colorado
When Colorado homeowners notice sticky leaves, black sooty mold, or patches of dying branches, they often assume it’s a fungus or lack of water. In many cases, the real culprit is a pest you almost never see: scale insects. Scale are silent feeders—small, immobile insects that attach themselves to twigs…

Why Tree Topping Is Dangerous
Tree topping is one of the most harmful—and unfortunately most common—pruning mistakes we see in residential landscapes. It’s often done with good intentions: a homeowner wants a shorter, safer, or “cleaner-looking” tree. But topping actually creates the opposite result. It makes trees weaker, uglier, and more likely to fail, while costing more money long term.

How Drought Stresses Trees Differently Than Heat
It’s easy to think that drought and heat are the same kind of stress for trees. After all, both usually happen in summer, both cause leaves to wilt or brown, and both are linked to water problems. But as an arborist, one of the most important lessons I teach homeowners is this: Drought and heat are two very different kinds of stress — and trees respond to them differently.

Why Hiring a Professional Tree Care Company with Certified Arborists Matters
Most homeowners call a tree service company when a tree becomes a problem—after a storm, when roots start lifting pavement, or when branches threaten the roof. But the truth is, tree care is a science, and the health of your trees affects your property long before issues become visible. That’s why hiring a professional tree care company staffed with certified arborists…

Dutch Elm Disease Back In Colorado
For many Colorado neighborhoods, mature elm trees are more than just landscaping—they are history. American elm and Siberian elm were widely planted in the early and mid-1900s for their fast growth, beautiful arching canopies, and deep shade. But today, elm populations face a serious threat: Dutch Elm Disease, one of the most destructive tree diseases in North America.

Soil Compaction in New Construction Sites
If you live in a recently built home—or are planning to plant a tree in a new development—you’ve probably noticed that landscape trees don’t always thrive the way they should. Even with watering, fertilizer, and good intentions, young trees often struggle, stunt, or decline early in new construction areas. In most cases, the underlying issue isn’t the tree—it’s the soil.

Understanding Fire Blight
If you’ve ever seen a branch tip on your flowering pear or crabapple suddenly turn black and curl over like a hooked cane, you’ve likely seen fire blight—one of the most destructive bacterial diseases affecting ornamental and fruit trees. Fire blight can ruin spring blossoms, kill young shoots, and spread into branches, and over time it can severely damage or kill the tree.
