Expert consultations and effective treatments.

Deep Root Fertilization

Why fertilize your trees & shrubs?

In our attempts to create an aesthetically pleasing urban landscape, we unwittingly disrupt the nutrient cycle that trees are normally a part of in the forest. By raking up leaves and removing grass clippings, we deplete the soil of nutrients over time. This may result in added stress to trees and shrubs.

At Forest Glenn Tree Care Inc., we understand that fertilization is an important part of tree care. Trees need certain nutrients (essential elements) to be healthful and to promote growth. Urban landscape trees are often grown in soil that does not offer sufficient nutrients for proper growth and development. In these situations, it may be necessary to fertilize to improve plant health. It is important to properly fertilizer as improperly applied fertilizer may actually harm the tree. In fact, some trees may not require fertilization.

Forest Glenn Tree Care Inc. provides deep root fertilization – a specialized process where a high-quality nutrient solution is injected directly into the root zone of trees. The nutrients are injected into the root zone under pressure which helps provide oxygen to the root system. The soil injection begins just below the surface and goes to a depth of  12 – 14 inches. Soil injection sites are placed about 2 or 3 feet apart in a grid pattern under the canopy area and beyond the drip line. The certified arborists at Forest Glenn Tree Care Inc. have the experience and skill necessary to ensure the right nutrients are applied correctly, at the right time.

Emerald Ash Borer Treatments

The Emerald Ash Borer (EAB) has killed millions of Ash trees in Ontario. The emerald ash borer attacks and kills all species of Ash trees except the Mountain Ash, which is not a true ash tree.

In Ontario, an effective pesticide to control EAB is the trunk injectable TreeAzin Systemic Insecticide. Forest Glenn Tree Care Inc. has professional licensed pesticide technicians on staff and is an approved provider of TreeAzin Systemic Insecticide.
