What Are Tree Injections?
Tree Injections are just as simple as they sound – they are shots for your trees. A solution is directly injected into the trunk so it can be transported to the rest of the tree via the vascular system. These injections are used to treat disease, eliminate invasive pests, and deliver essential nutrients to correct deficiencies.
How Do Tree Injections Work?
Tree Injections are a highly effective treatment methods for trees suffering from disease, infestation, or extreme nutrient deficiency.
Small holes are drilled into the trunk of the tree, going through the bark and other outer layers (such as the phloem and cambium) and stopping at the xylem. The xylem contains a sapwood layer that is responsible for transporting water and minerals throughout the entire tree. The appropriate formula, as determined by one of our trained technicians, is then pumped into the tree. The xylem vascular system does all the work after that, ensuring the product is distributed from the roots of the tree all the way to the canopy. Unlike other treatments, Tree Injections can provide protection for up to two years.

How Much Does It Cost for Tree Injections in Toronto?
Pricing for Tree Injections in Toronto varies based on the size of a tree requiring treatment. Local Arborist charges $10 per inch of the trunk diameter. So, for example, a mature Sugar Maple with a trunk diameter of 25 inches would cost approximately $250 for a Tree Injection service.
For the most accurate estimate, it is best to contact Local Arborist. We provide complimentary consultations for basic tree assessments.
Common Pests and Diseases That Can Be Treated with Systemic Injections

Fire Blight
Fire Blight is a bacterium that infects the tree through blossoms, leaves, or stem wounds. It is extremely detrimental to fruit producing trees (so much so that it has the capability of wiping out an entire orchard in a single growing season if not immediately treated). Tree injections, when applied in early spring, are highly effective at treating Fire Blight.

Poplar Borer
The Poplar Borer is an invasive beetle species that lays its eggs in the bark of the tree (typically aspens). When the eggs hatch, the larvae feed on the bark and sap until they begin pupation. Fully matured Poplar Borer’s finally emerge in summer months and strip trees of their leaves and new shoots. Tree injections are one of the best ways to treat for Poplar Borer.

Bronze Birth Borer
Bronze Birch Borers is a common wood borer species that is detrimental to all birch species in Toronto, and throughout North America. The larvae cause the most damage to the trees by feasting on the xylem vascular layer that is beneath the bark. Tree Injections effectively kill both the larvae and adult beetles of the Bronze Birth Borer.

Birch Leaf Miner
The Birch Leaf Miner is one of the most common insects that affect birch trees. Tree Injections are effective at controlling Birch Leaf Miners because of the systemic spread of insecticide through the entire tree, including the leaves that the larvae feast on.

Aphids
Aphids are small, but devastating insects. These little sapsuckers feed on leaf buds and new shoots, weakening the tree and making it more susceptible to disease. Additionally, aphids secrete a sticky substance called “aphid honeydew” that attracts other pests, such as ants. Insecticides that can be directly injected provide the most comprehensive protection against aphids.

Spruce Sawfly
Spruce Sawflies get their name from the sharp dagger-like part on their head that they use to cut holes in trees and deposit eggs. They are efficient eaters and will almost entirely clean the needles off a spruce tree. Systemic insecticide applied with tree injections successfully control Spruce Sawflies.

Cottony Psyllid
Cottony Psyllids are small, soft-bodied insects that resemble aphids. This highly invasive insect species infects both Manchurian and Black Ash trees. Insecticide treatments, such as Tree Injections, have proven to be highly effective in dealing with Cottony Psyllid.

Emerald Ash Borer
If a tree becomes infested with Emerald Ash Borer, it is almost guaranteed to die. The larvae tunnel under the bark and disrupt the flow of essential nutrients throughout the tree. Your first indication of an infestation may be the leaves thinning out at the top of the tree.
