A Multivitamin for Your Tree
Deep root injection treatments provide your trees with the added nutrients they need to stay healthy, much like multivitamins do for us.
Treatments encourage new, lush growth and help protect your trees from insects, diseases, and environmental stressors.

Deep Root Fertilization Services
What trees require in the fall is different from what they require in the spring. We apply solutions suited to the time of year, to prepare your trees for the conditions ahead.
Spring Fertilization
In the spring, your tree wakens from its time of dormancy. The roots have expanded during the cold months and are ready to go to work. New leaves are bursting to begin the photosynthesis process. Fertilization applied at this time of year will help the tree to maximize its ability to promote new growth.
Fall Fertilization
During the winter months while your tree appears dormant above ground, the root system will expand taking in water and nutrients. Fertilization applied in the Fall supports this growth and development.
To receive maximum effectiveness, treatments are administered in both the spring and fall; however, receiving one injection per year is also beneficial.

When is Deep Root
Fertilization Beneficial?
In a residential setting where leaf litter and decomposing organic matter are constantly removed, the ground can become robbed of essential nutrients. Your tree is forced to compete with the sod for nourishment, which can lead to a nutrient deficiency.
Without these nutrients, trees are less equipped to deal with environmental stressors, insects, and diseases. The tree loses its healthy, lush appeal.
We bring trees back to good health by injecting liquid fertilizer underneath the turf, which eliminates competition between the tree’s root system and the sod, delivering it directly to the roots.
Because deep root fertilization is injected into the ground, it also helps loosen the soil to reverse the effects of root compaction.

Is Deep Root Fertilization
Right for My Trees?
All trees and shrubs can benefit from deep root fertilization to maintain their health and promote new growth. Trees that are protected from environmental stressors live longer and look healthier.
There are several scenarios that deep root fertilization can benefit…

frequently asked questions
1. How quickly will I notice a difference after deep root fertilization?
Typically, our clients notice an improvement after the first injection. For maximum benefit, we recommend that your tree receive at least one full cycle initially (spring and fall) and then yearly at minimum after that.
2. How long do I need to continue to treat my tree?
The answer varies depending on the outcome you are looking for. For those who regard deep root treatments as a short term method of assisting their sick/weakened trees back to health, the applications may last for one to two seasons.
Many of our clients look upon their trees as a long term investment and consider a yearly or twice yearly application of fertilization as a multivitamin to maintain its health and vitality on a long term basis.
