Services
Tree Pruning
Our tree pruning service enhances tree health and structural integrity through strategic branch removal. We use techniques like crown cleaning, thinning, and canopy lifting to reduce storm damage risks while maintaining natural growth patterns. Regular pruning mitigates hazards and beautifies landscapes across Boulder, Colorado.
Tree Removal
We safely remove hazardous or deceased trees using professional equipment and techniques. Our experts assess structural risks like decay, leaning, or pest infestations to determine when removal is necessary. We handle large-scale projects while protecting surrounding property and ensuring proper stump management.
Deep Root Watering
This service delivers essential nutrients and moisture directly to tree root systems using specialized injection techniques. We address Colorado's semi-arid climate challenges by improving soil conditions, enhancing drought resistance, and promoting vigorous growth for urban trees through balanced fertilization programs.
Stump Grinding
Our stump grinding service eliminates tree stumps below ground level using modern equipment. This prevents regrowth, removes tripping hazards, and allows for landscaping reuse. We contain debris during operations and restore ground surfaces for seamless property integration after tree removal.
Cabling and Bracing
We install dynamic cabling systems to reinforce structurally weak trees while preserving their natural form. This service reduces failure risks in trees with splits, cracks, or heavy limbs by redistributing stress without compromising biological health, extending the life of valuable trees.

Aaron was able to meet with me quickly and knows so much about trees. Even the history of the local weather that damaged an ornamental fruit tree and what could be done for it at this point. His crew did a great job pruning with a thorough clean up afterwards. Highly recommend Mountain Tree Care.

Long story short, we had to get a Box Elder removed and needed it done quickly. Mountain Tree Care came right out and gave us an estimate and were able to get a crew out there to complete the job within a week. They did a fantastic job. Both Caleb and Jacob were prompt, professional, friendly, and did a great job cleaning up afterwards. There were some obstacles that made cutting the stump low difficult, but they took their time and got it lower than we even expected. I highly recommend Mountain Tree Care!

Mountain Tree Care did a great job of removing my two trees. Clean-up was great, you would never know they there. Price was great, and my work was scheduled quickly. I would use again and recommend.

Aaron and his team were fantastic! I asked for some work on a quince bush, as well as taking down a dead pine tree. The work performed was extremely fast, looked outstanding, and the crew even showed up a little early! Absolutely fantastic people, very easy to work with, and well worth the money. Ill definitely be calling them again next spring.

I employed Mountain Tree Care to remove two pairs of large aspens that were dead or dying. They were very prompt in getting back to me with a quote. The date was quite a long way in the future because of the demand for their work, but they duly arrived at the time and date promised and very efficiently removed the trees. The stumps were ground out the same day, and they tidied up after the removal.

The workforce that arrived knew exactly what they were doing, including some specific requirements I had mentioned when first booking the work. Overall I was very impressed with their professionalism
