Aurora Is a Hard Place to Be a Tree

Alkaline clay soils, high-altitude sun, wild swings between a 70-degree afternoon and an overnight freeze, and heavy spring snow loads on green ash and Siberian elm all put Aurora's trees under stress that Front Range homeowners rarely see coming. A tree that looks fine in June can be structurally compromised by August - and most people don't know their tree is in trouble until a limb drops on the driveway or a whole canopy thins out over one summer. By then the choices are fewer and more expensive. Waiting costs more.

The newest threat makes waiting even riskier: the emerald ash borer was confirmed in Aurora in September 2025 near Quincy Reservoir, and the city estimates roughly 110,000 ash trees here - about 90% of them on private property, which means the bill for that infestation lands on homeowners, not the city. Left untreated, an infested ash almost always dies, and dead ash wood turns brittle and dangerous to remove. A salesperson sees a removal; a certified arborist looks at your specific trees and tells you plainly what's healthy, what's at risk, and what can wait - with a written quote before anyone touches a saw.

Tree Removal

Safe, controlled takedowns for dead, hazardous, or declining trees, including tight-access Aurora lots and trees near homes and power lines. When removal is the right call, we say so; when it isn't, we tell you that too.

Tree Trimming & Pruning

Structural and health pruning to ANSI A300 standards that reduces storm risk and keeps mature trees strong instead of over-thinned.

Stump Grinding

Removes the trip hazard and re-sprout risk left after a removal, restoring usable yard space.

Pest & Disease Control

Diagnosis and treatment for the insects and diseases that hit Denver species hardest, from a Certified Spray Supervisor.

Lawn Fertilization & Weed Control

Turf care that complements a healthy canopy across your property.

Tree Injections

Targeted trunk-injection treatments, including EAB protection for high-value ash trees.

We also provide plant healthcare, deep-root fertilization, EAB treatment, arborist consulting,

commercial and HOA contracts — one certified team for the whole property.

Aurora's Trees, Neighborhoods, and Real Threats

Neighborhoods

We work across Aurora every week — Saddle Rock, Southshore, Tallyn's Reach, Murphy Creek, Green Valley Ranch East, Seven Hills, and the mature canopy of Heather Gardens. The species we see most are green ash, Siberian elm, cottonwood, honeylocust, maple, linden, crabapple, blue spruce, and Austrian pine. Each has its own vulnerabilities, and knowing them is the difference between a treatment that works and money spent guessing.

Emerald ash borer (EAB)

An invasive beetle whose larvae tunnel under ash bark and cut off the tree's ability to move water and nutrients, killing untreated ash trees over a few seasons. EAB attacks ash specifically. It was confirmed in Aurora in September 2025 near Quincy Reservoir, and because the city estimates roughly 110,000 ash trees here — about 90% on private property — the cost of that infestation lands on homeowners. Preventive trunk-injection treatment can protect a healthy ash that isn't yet heavily infested.

The Ips beetle (engraver beetle)

A bark beetle that attacks stressed or drought-weakened spruce and pine, boring into the inner bark and often introducing blue-stain fungus. The early sign is fading, reddening needles at the top or one side of the tree — so keeping conifers watered and fertilized is a frontline defense on the dry Front Range.

Which path fits your tree depends on the tree in front of us — that's why every job starts with a certified arborist walking your property, not a phone estimate.

Aurora Rules

Aurora City Code Sec. 26-528 makes it unlawful to operate a tree cutting, trimming, or removal business in the city except under the direction of a licensed arborist. When you hire us, that requirement is already met. For rules that apply to your own property, always confirm current permit requirements with the City of Aurora before removal, as codes can change. We'll walk you through what applies to your property during the assessment.

Do I need a permit or license to remove a tree in Aurora?

For rules that apply to your specific property, confirm current requirements with the City of Aurora before removal.

My ash tree looks fine — should I worry about emerald ash borer?

Because the city estimates about 110,000 ash trees here — roughly 90% on private property — an assessment now tells you whether trunk-injection treatment makes sense for your tree.

What areas of Aurora do you serve?

Are you insured?

Yes, Ironwood Earthcare is fully insured with both general liability and workers' compensation coverage. That protects you and your property throughout every job.

How do you decide whether to treat or remove a tree?

We base the decision on an on-site inspection of the tree's health, structure, and risk. A healthy or moderately declining tree with good structure is often a candidate for treatment, while a dead or hazardous tree is usually safer removed — and we tell you honestly which one you're looking at.

Why choose a certified arborist over a general tree service?

An ISA Certified Arborist is trained to diagnose tree health, not just cut branches, so you avoid unnecessary removals and improper cuts. Ironwood's work follows ANSI A300 standards, and founder Derek Stroden also holds a forestry degree and a state spray supervisor certification.
