Deep Root Fertilizing

Deep root fertilizing is a process in which a water-soluble fertilizer is injected into the soil surrounding the root system of a tree using a hydraulic fertilizer injector. The injection extends from the surface of the lawn to 10 to 12 inches below ground level.

Fertilizing is best done in the spring and in the fall.

The trees take up the fertilizer through their roots and use the nutrients for root development, disease resistance and new growth.

In addition, the bore holes from the feeder probe serve to aerate the soil which encourages root growth and increases the additional absorption of oxygen, water and nutrients to the tree.

It is recommended that fertilizing be done every season to maintain your tree’s healthy vigour.

We use fertilizers from Growth Products, Ltd. who have been developing and manufacturing fertilizers for over 25 years. You can visit their site at
