Cohan & Master Tree Services introduces TreeAzin™ Systemic Insecticide, the latest tree remedy of our Plant Health Care Plan. TreeAzin™ protects against the Emerald Ash Borer (EAB), a highly invasive green beetle, recently introduced to North America from Eastern Asia. Since its detected arrival in 2002, the Emerald Ash Borer has attacked millions of Ash trees across North America, including the Greater Toronto Area.

Over the years we have seen the devastating effects of EAB, taking over healthy Ash trees of all sizes in the GTA and destroying our urban canopy. If left untreated, Ash trees within Ontario will certainly disappear in the near future. The spread of EAB is caused naturally by species migration and artificially as people transport infected ash materials and firewood to new areas.

Cohen & Master Tree Services are happy to announce a solution with the addition of the TreeAzin™ treatment, that successfully protects against the Emerald Ash Borer. This specially formulated product is the only registered treatment for the Emerald Ash Borer in Ontario, owned by the Canadian Forest Service (CFS) and was developed in collaboration with BioForest Technologies Inc. TreeAzin™ Systemic Insecticide is produced from the extracts of Neem tree seeds (Azadiracta indica), which has been used for centuries to control and protect against pesty insects.

The ice and snow are finally melting away and the outdoor world, dormant all winter long, is waking at last to another growing season.

Plant a new tree for your enjoyment today and for future generations.

Something we often ask our clients to consider at this time of year is the tree below the ground. The canopy, branches and leaves of a tree naturally draw most of our attention but we should remember that this is only a portion of the tree structure. A good tree requires strong and healthy roots.  We like to offer this reminder as many of the tree problems that we see are related to a root issue. Roots are often compromised in the city by poor soil conditions, physical barriers, and construction activity. Spring and summer are the time to build, renovate and landscape in Canada and too often we see the root zones of trees irreversibly damaged during this process. This can simply be avoided if the proper tree protection measures are put in place. Another root problem that we frequently see develops when new trees are improperly planted.  Roots become greatly affected and the new tree will never thrive if planted too deep in the soil, left in the wire and burlap, or “volcano-mulched” too high and too close to the main stem. Talk to your Cohen & Master arborist about the roots of your trees. We offer tree protection plans and expert tree planting.

Contact Cohen & Master today. Our arborists can provide a free, no-obligation inspection of the trees and shrubs on your property. We will work with you to address specific concerns and make recommendations to benefit the long-term health and beauty of your trees and shrubs.
