Tree Injection Specialists

Environmentally Friendly Insect Control

Ross Tree Company prides itself on being one of the first companies to offer tree injections, a viable alternative to spraying trees. Trunk injections ensure that it is only the tree getting the treatment and that no off-drifting of fertilizers occurs. No need to close windows or cover items near the trees being treated and no unnecessary fertilizer getting into the environment. Trunk injections will protect your trees for the entire growing season as compared to multiple spray treatments that only control what is present at the time of treatment. While tree injections are best, spraying can be warranted due to a tree insect infestation or disease that needs immediate attention in order to save the tree. Ross Tree will sit down with the residential or commercial property owner to discuss all options before treatment commences. For environmentally friendly plant health care services, click here to fill out a service request form or call 303-871-9121. We are at your service.

Trunk injections can treat your trees for a variety of tree insects such as Aphids, Emerald and Lilac Ash Borers, Mountain Pine and IPS Engraver Beetles. Tree injections can also treat nutrient deficiencies or control tree diseases.

Environmentally Friendly Insect Control

Some tree insects are beneficial or benign while others are harmful to trees and require environmentally friendly insect control from Ross Tree Company. We take our motto Integrity in Action seriously and commit to using only the necessary products to control tree pests and nothing more. We have three Qualified Supervisors (QS) licensed by the Colorado Department of Agriculture to handle tree pesticide products and to identify if a tree insect is a friend or foe. Please see our insect calendar to find out more information about local harmful tree insects and diseases.

Emerald Ash Borer Treatments

As our blog post stated today, the Emerald Ash Borer (EAB) is moving toward Denver. Prevention is the key against the EAB. Once a homeowner sees borers around their Ash tree, it is probably too late to save it. Ross Tree uses tree injections to control these tree insects. We are a licensed Colorado Department of Agriculture Commercial Pesticide Applicator and offer several effective treatment options for controlling EAB. Tree injection can protect a tree for up to two years and is up to 95% effective against the EAB. Click her for more information about the Emerald Ash Borer.

Thanks for being so accommodating, crew did a great job as usual.
