Soil conditions in Alberta can be harsh on developing trees and shrubs. Healthy plant growth relies on minerals and micronutrients which may not be present in full to absorbing roots. Our specialized equipment injects a blend of water and fertilizer around the drip line of the tree, below grass roots where uptake is readily available. Dependent on the time of year applied, our fertilizer will either systemically supply minerals and micronutrients upwards aiding in canopy growth, or downwards focusing on root development.

Because insects can rapidly deteriorate the aesthetic and health of a tree, it is important to monitor your property periodically throughout the growing season. Our primary tree spray for insect control is an environmentally friendly, biodegradable product.
Our tree and shrub health program will aim to reduce insect populations by treating your plants with insecticidal soap up to three times through the season. Approximately every five weeks, our staff will monitor your yard and only spray when necessary. The tree and shrub health program will also include one deep root fertilization in spring or fall to aid in tree and shrub health.
We also offer tree spray services on a one-time basis, dependent on your landscapes needs.
When required, we may recommend the use of Trounce in severe infestations, horticultural oil to suffocate eggs, or in some cases, the systemic insecticide, Orthene.

In addition to insects, fungus and bacteria can cause issues with tree growth and health. Disease can spread by many factors including wind, rain, insects, and wildlife. It is important to catch disease early as it can spread within the canopy of the tree, as well as to other trees close by.
Common diseases in Alberta include:
- black knot
- bronze leaf disease
- septoria canker
In most cases, control of disease includes pruning out the affected areas and sanitizing equipment. In severe cases, where the disease can not be controlled, the entire tree may need to be removed.
Dutch elm disease is a concern in Alberta and fortunately Alberta’s elms have been free of this disease. By-laws in place to control the spread of Dutch elm disease include pruning of elm trees only when the tree is in its dormant stage and to not introduce firewood from other areas.
