Paul Donovan is an International Society of Arboriculture (ISA) Certified Arborist with 18 years of experience in the Front Range.

We also offer consulting services in Tree Hazard Evaluations, Tree Appraisals and Defensible Spacing for mountain properties. Tree Trimming and Pruning: Did you know that properly pruned trees live longer and retain a pleasing, natural appearance? Tree trimming and pruning encourages air circulation which reduces disease incidence and the possibility of damage from high winds. Tree Fertilization Services: Applying a slow-release tree Fertilizer is one of the most important things needed to replace nutrients, improving resistance to damage from diseases, insects and stressful weather. Shrub Pruning Services: Professional shrub pruning requires a certified arborist's ability to accommodate the plant's physiological needs with the desired aesthetic look. Heavy snow, freezing rain, lightning, high winds or a combination of any of these severe weather outbreaks can stress your trees from their root systems all the way to their branches and leaves. Proper tree maintenance can reduce damage to your trees and property, maximizing your safety. It's a simple fact: healthy landscape trees endure summer storms better than unhealthy trees. There are three factors that come into play when you're preparing your trees for high winds and severe weather: the density of the tree canopy, the strength of the branches and the health of the root system. Preventative Pruning: Regular tree maintenance can mean a world of difference when it comes to tree strength during a storm. Preventative pruning to thin the top of the tree the canopy reduces wind resistance and in turn, the force that can damage branches or even the trunk of the tree. In addition, pruning removes dead branches that can break easily, causing damage to the tree and the surrounding landscapes. Strong branches are better able to withstand high winds. Both the size of a branch and the size of its attachment to the rest of the tree determine its strength, so careful evaluation is needed to determine which branches may need to be removed or reinforced by cabling and bracing. Mulching: Protecting the root system of the tree is important, too. A wide mulch ring around the base of the tree removes the need to use lawn mowing equipment close to the roots of the tree, minimizing damage, and also allows water and nutrients to drain down through the soil to the roots. Lightning Protection: In addition to the excessive forces that come with summertime storms in the form of high winds, lightning is also a concern with summer storms. Lightning will strike anything that provides a good path for the electrical.

My family and I were on vacation when our neigbor called us and let us know that our tree was broken because of a storm. Paul came to our house and fixed the mess. Cleaned up after and gave us a very affordable bill. We are happy we called Donovan Arborist.

Tree Planting

This past winter we hired Donovan Arborists to plant trees at our new home. Paul came out and went over all the options that would work for us taking into account location of tree, if for decoration or shade and soil type. After we decided on the trees that we wanted him and his crew came over and planted all 5 of the trees we picked out. He even gave us a one year warranty. Well I was waiting to see how the trees would take to the yard, and this past summer I was impressed at how well they have done. They were the perfect trees and seem to be thriving. I will definitely use Donovan Arborists for all my tree needs.
