Most shade trees benefit from pruning during late winter dormancy (December through February) when branch structure is visible and disease transmission risk is lowest. Spring-flowering ornamentals should be pruned immediately after blooming. Deadwood removal and hazard limb pruning can be performed any time of year. We recommend avoiding heavy pruning during the active growing season (May through August).

ISA-Certified Arborists provide evidence-based tree care grounded in arboricultural science. For services involving structural pruning, pest and disease diagnosis, risk assessment, and removal of large trees near structures, professional arborist oversight ensures the work is performed correctly and safely. Our arborists also identify developing problems that untrained workers would miss.

If you have green or white ash trees in good health, preventive trunk injection treatment is the most cost-effective approach. Treatment is significantly less expensive than removal and replacement, and effective treatments can protect trees for 2–3 years per application cycle. Trees already showing significant canopy decline (more than 50% dieback) may be past the point where treatment is viable.

Common signs of a potentially hazardous tree include visible trunk cracks, large cavities or decay, codominant stems leaning apart, mushroom or fungal growth at the base, recent soil heaving near the root plate, and significant deadwood in the canopy. If you notice any of these conditions on a tree near your home or outdoor living areas, a professional risk assessment provides objective evaluation and documented recommendations.

Yes. Many Aurora neighborhoods are HOA-governed with specific landscape and tree care requirements. We coordinate with HOA management for removal approvals, provide documentation when required, and ensure our work meets community standards. Our arborists can also provide written recommendations that support removal or treatment requests submitted to HOA boards.

Drought-adapted species that tolerate alkaline clay soils perform best in Aurora. Proven performers include bur oak, Kentucky coffeetree, hackberry, honeylocust, northern catalpa, and Shumard oak for shade trees. For smaller ornamental trees, Tatarian maple, Amur maple, and hawthorn varieties handle Aurora's conditions well. Native conifers including ponderosa pine, pinyon pine, and Rocky Mountain juniper are excellent choices for evergreen screening and windbreaks.
