Arbor Services

Trees are a valuable part of your commercial landscape—and they require specialized care to stay healthy in Colorado’s challenging conditions.

Keesen Landscape provides commercial arbor and tree care services throughout Denver, Colorado Springs and the Front Range. Our team helps property managers, HOAs, developers and commercial property owners proactively manage tree health, address potential concerns and maintain trees that contribute to a safe, attractive landscape.

From routine pruning to plant health care, we take a thoughtful approach based on the needs of your trees and the property around them.

Commercial Tree Care for Colorado Landscapes

Colorado trees face a unique combination of environmental stressors. Dry conditions, temperature swings, winter weather and pest and disease pressures can all affect tree health over time.

Regular monitoring and timely care can help identify concerns before they become larger problems. Keesen incorporates tree care into the broader management of your commercial landscape, allowing our team to consider how irrigation, soil conditions, surrounding plant material and seasonal conditions may be affecting your trees.

Our goal is straightforward: support healthy trees while helping you maintain a safe, well-cared-for property.

Our Commercial Arbor Services

Tree Pruning

Proper pruning supports tree health, structure and appearance while helping maintain clearance around sidewalks, parking areas and other frequently used spaces.

As part of Keesen’s landscape maintenance program, our teams can prune low-hanging branches under 12 feet in turf areas, landscape beds and along sidewalks. Your Account Manager can also recommend more comprehensive tree trimming when appropriate.

Tree Removal

When a tree needs to be removed, careful planning matters—especially on active commercial properties. Tree removal may be appropriate when a tree presents a concern for the property or no longer fits the long-term needs of the landscape.

Our team can help evaluate the situation and coordinate the appropriate next steps with your property’s safety, appearance and surrounding landscape in mind.

Stump Grinding

After a tree is removed, the remaining stump can interfere with landscape maintenance, future improvements and the overall appearance of the property.

Stump grinding helps prepare the area for its next use and creates a cleaner, more finished landscape.

Tree & Plant Health Care

Healthy-looking trees start below the canopy. Keesen offers specialized plant health care services designed to address the changing needs of Colorado landscapes throughout the year.

Depending on your property and plant material, recommended services may include:

• Deep-root fertilization
• Micronutrient fertilization
• Dormant oil treatments
• Insect and disease treatments
• Emerald ash borer treatments
• Birch borer treatments
• IPS beetle treatments
• Spruce gall treatments
• Supplemental winter watering

Treatment timing and recommendations depend on the landscape, environmental conditions and specific concerns present on the property. Keesen’s maintenance calendar includes seasonal windows for these services rather than treating tree care as a one-time event.

Proactive Tree Health Monitoring

Tree problems are easier to manage when they are identified early.

Our teams continually observe the landscapes we maintain for signs of pests, disease, stress and other concerns. When an issue is identified, we communicate what we see and recommend an appropriate course of action.

Keesen also utilizes specialized technical service personnel for services such as Plant Health Care, giving your Account Manager access to additional expertise when your landscape needs it.

Winter Tree Care on Colorado’s Front Range

Tree care doesn’t stop when the growing season ends.

Colorado’s dry winters can place significant stress on trees, particularly evergreens and other susceptible plant material. When conditions warrant it, supplemental winter watering can help maintain important soil moisture around tree roots and support plant health heading into spring.

Your Keesen team can evaluate seasonal conditions and recommend winter care based on the needs of your property.

Arbor Care as Part of Your Complete Landscape Program

Trees don't exist separately from the rest of your landscape. Their health can be affected by irrigation, soil conditions, surrounding plants and how the overall property is maintained.

That’s why Keesen approaches arbor care as part of a larger landscape management strategy.

Your Account Manager serves as a dedicated point of contact and works with production teams and technical specialists to monitor your property, coordinate services and identify opportunities for improvement.

It’s a more connected approach to commercial tree care—and one designed around the long-term needs of your landscape.

Frequently Asked Questions About Commercial Tree Care

What commercial tree services does Keesen provide?

Keesen provides commercial tree pruning and plant health care services, including seasonal treatments, fertilization and pest and disease management. Our team can also help address tree removal and stump grinding needs as part of the overall management of your landscape.

How often should commercial trees be pruned?

There isn't one pruning schedule that works for every tree. Species, age, location, growth habits, condition and the needs of the surrounding property can all affect when pruning is appropriate. Keesen evaluates the needs of the landscape and recommends service accordingly.

How do I know if a tree on my property is unhealthy?

Changes in foliage, dead or damaged branches, thinning canopies and signs of insects or disease can indicate that a tree needs attention. Regular landscape inspections can help identify concerns and determine whether specialized care should be considered.

Do trees in Colorado need winter watering?

They can. Dry winter conditions along Colorado's Front Range can reduce available soil moisture, and Keesen specifically recommends supplemental winter watering when appropriate to support tree health. Evergreen trees can be especially susceptible to cold, dry conditions.

Does Keesen provide tree care for HOAs and commercial properties?

Yes. Keesen's services are designed around professionally managed commercial landscapes, with customized service programs rather than a one-size-fits-all maintenance schedule.
