How Does Tree Injection Work?
We use Arborjet’s IMA-Jet to provide protection and quality nutrients like phosphorous, potassium, iron and low dose nitrogen to your trees. Arborjet’s products are injected directly into the transport system of your trees to ensure the treatment is Fast Acting, Effective, Environmentally Responsible, & Long Lasting.
A small plug, called the Arborplug® is inserted into a drilled hole in the tree. A needle is inserted through the Arborplug® and the treatment is injected. A precise dose of formulation is injected directly inside the transport system of the tree. Formulations are quickly distributed through the trunk, branches and leaf tissue.
The Arborplug® keeps the injected formulation inside the tree and it stays inside the tree with no adverse reactions. The tree grows right over the Arborplug®.
Serving Calgary, Lethbridge & Surrounding Areas
From the urban trees in Calgary’s inner city to wind-battered trees across Lethbridge, we’re ready to help restore and protect your landscape. Whether you’re dealing with a pest issue or just want to boost your tree’s health, we’ve got you covered.
Leaf Miner & Aphid Control
Dry summers and dense urban plantings in Calgary and Lethbridge make trees especially vulnerable to leaf miners and aphids. Our tree injections target these pests quickly and cleanly, without the need for harsh sprays.
Tree Fungus & Disease Management
With Calgary’s late frosts and Lethbridge’s windy, dry climate, local trees are prone to fungal infections like blight, mildew, and canker. We diagnose and treat these issues directly through the trunk for faster recovery and longer-lasting results.
Emerald Ash Borer Treatment & Prevention
Emerald Ash Borer has made its way into southern Alberta, and Calgary and Lethbridge are no exception. Our injections offer proactive and effective protection to preserve ash trees before irreversible damage sets in.
Nutrient & Fertilizer Injections for Health & Growth
With nutrient-poor soils in many Calgary and Lethbridge neighborhoods, trees often struggle with slow growth and yellowing leaves. Our customized injections replenish essential nutrients, helping your trees bounce back stronger and healthier.
Urban Stress Recovery
From heavy sidewalk traffic in Calgary to chinook winds and drought conditions in Lethbridge, urban trees face daily stress. Our deep-root and trunk injection treatments help trees recover from damage caused by compaction, de-icing salt, and environmental extremes.
Insect & Pest Injections
Southern Alberta’s mix of ornamental and native trees are frequent targets for scale, spider mites, and wood-boring insects. Our arborists deliver targeted treatments straight into the tree, reducing infestations from the inside out.

Our Happy Clients
“Had 2 Brandon Elm trees treated, one for bugs plus a growth boost vitamin, other for a small fungal infection which came recorded, reply and communication was excellent, all my questions and concerns answered, work was done as scheduled, fingers crossed for results, easy payment. Thx A1 tree service.”
– Chris Cushman
“100% awesome job for cutting the tree, recommend them“
– Deng Pavel
“Fast and professional service! I was really impressed with the way Mat got the yard cleaned up after that huge tree was removed and the small ones shaped beautifully! The stump removal was complete and the yard was so nice after he left. The quote was very fair, I am glad I didn’t use the cheaper guy my friend recommended, because the stump the other guy left in her yard was still visible and bumpy in the lawn. It is worth it to hire A1 “get er done” because they DO get it done, the huge tree taken down and the stump completely removed so I can have a beautiful lawn this summer. If you want the job done right at a very fair price, I recommend this company.”
