Donovan Arborist

We strongly believe in being proactive when it comes to trimming and pruning the trees on your landscape. Our clients rarely experience limb failures during Colorado's spring snow or wind storms, and staying on top of at-risk areas of your plants is not only cost-effective, but diminishes complications while keeping them healthy, safe and beautiful. To keep branches from breaking in a wind or snow storm, pruning cuts are made near the tips of heavier branches to reduce weight. We also clear the branches from structures, pathways and service lines.

Flowering deciduous shrubs offer fluidity in the landscape with renewed growth in the spring, foliage and flowers in the summer and dormancy in the winter. Evergreen shrubs offer an air of permanence and continuity in the landscape. Like trees, shrubs in the Denver area need to be pruned to improve health and appearance. Pruning shrubs periodically keeps them full of foliage and flowers. Donovan Arborists prefers to prune most shrubs by hand. In doing so, any dead and diseased stems are removed and proper pruning cuts are made in shaping the shrub to its natural form.

You can rest assured knowing that we will remove your tree in a safe and fast manor. We view tree removal as an art and understand that our customers want to hire a company that will be respectful of their property. We have been removing trees in Denver for two decades and have never had property damage claim. We have all the right equipment to protect your house and existing landscape while performing a tree removal. We are skilled in crane assisted tree removals.

We can also remove trees and shrubs and replace them with new plants that will thrive in your location.

When done correctly, tree trimming (also known as tree pruning) improves the health, appearance and safety of your trees. By diminishing the pressure that insects put on trees, trimming also reduces the need for pesticide use. Donovan Arborists believes when we are finished trimming a tree, it should still look like a tree. With Denver's dry climate, hot summers and cold winters it is extremely important not to remove too much foliage. A lot of clients are under the impression that the more we prune off a tree, the more they are getting for their money - this is not always the case.

We offer a complete landscape maintenance package. We make it easy for property managers that want one company to provide a variety of services. We specialize in the care of trees growing in difficult sites, and can help you develop a Plant Health Care Program to ensure your trees and shrubs stay insect and disease free.

Donovan Arborists hires International Society of Arboriculture (ISA) Certified Arborists to ensure that you get the highest quality tree care. We offer on-going training to ensure our arborists are knowledgeable, safe and friendly. Properly cared for trees can add as much as 20% to the value of property. We are passionate about offering pro-active tree care in an environmentally friendly manor. This practice is the basis to producing a landscape that flourishes while requiring less maintenance over time.

Donovan Arborists grinds to a depth of 8-10 inches below ground level. This process produces a wood chip and soil mixture that is great to use as compost. If you do not want the compost, we can rake the area level and haul away the excess debris. If you are planning on planting another tree or turf in the same area, we recommend having us clean the stump hole of the wood chip and soil mixture and backfilling with top soil. New plants have a difficult time getting established in the compost mixture.

We believe in being proactive in preventing insect infestations and disease outbreaks in our customer's trees and shrubs. This starts with identifying the pest risk for plants before it becomes an overwhelming issue. Carefully monitoring and assessing the new or existing pest situation ensures action is taken as soon as possible to prevent further outbreak. Our organic-based fertilizer gives your trees and shrubs the nutrients they need in order to thrive. We focus on the root and soil relationship.
