The Big Ash Tree Company

The Big Ash Tree Company is serving the entire Denver Metro Area, with over 40 years experience. We treat trees with an injection directly into the tree or the use of systemic trunk sprays and soil injections. If trees are healthy, they can fight off or recover from damage quicker, we are firm believers in deep root fertilization. Tree wellness starts with a healthy root system, healthy, vibrant soil; its health from the ground up, one tree at a time.
Your trees will always be inspected by a Certified Arborist. All evaluations and proposals will be written or emailed if requested, and always done at no cost to you. Systemic insect and disease treatment is our expertise. Trunk injections, systemic trunk applications and soil injected systemic are the techniques we employ. We will assist you with the decision to treat your trees or not to treat your trees.
We will explain the ramifications of treating as opposed to letting "nature takes its course". Our goal is to protect your valuable trees using the minimal amount of pesticides. One of the injection systems we use "Arborjet", can be used on almost any tree for almost any insect or disease. Again, each tree must be evaluated on an individual basis, you will be supplied with an educated and honest assessment of each tree. Please note: We do NOT do any pruning, trimming or removals, but will recommend a professional licensed company should the need arise.
