Our Plant Health Care Services
Direct Stem Injections (Arborjet® System)
We protect trees with precise, trunk-injected treatments that deliver targeted control with minimal impact on your property. Unlike broad chemical sprays, stem injections send solutions directly into the tree’s vascular system for long-lasting results.
Common treatments include:
- Hemlock Woolly Adelgid (HWA)
- Emerald Ash Borer (EAB)
- Needlecast diseases
- Cankerworms
This method ensures effective treatment while protecting pollinators, soil, and nearby water sources.Common treatments include:
Tree Banding (Cankerworms)
We install protective tree bands to stop cankerworm caterpillars before they can damage foliage. This eco-friendly, non-chemical method interrupts their life cycle and prevents widespread defoliation.
Soil Injections
We strengthen trees from the ground up with targeted root-zone treatments:
-
NutriRoot®
A blend of nutrients, organic matter, and moisture management technology that encourages strong root growth, reduces transplant shock, and enhances drought resilience. -
ShortStop®
A growth regulator that slows excessive canopy growth, redirecting energy to the root system. This improves drought tolerance, enhances structural integrity, and promotes long-term health.
By improving root strength and soil health, these treatments help trees thrive even under stress.

Plant Health Care FAQs
How do stem injections compare to spraying?
Injections deliver product directly into the tree’s vascular system, which means no drift, no exposure to non-target plants or pollinators, and longer-lasting results.
How often do treatments need to be applied?
Frequency depends on the pest or disease. For example, Emerald Ash Borer treatments may last 2–3 years, while other treatments may require annual applications.
Will soil injections affect my lawn or garden?
No. Our NutriRoot® and ShortStop® injections are applied directly into the root zone of your tree and are designed to support soil and root health without harming surrounding turf or plants.
Can PHC save a tree that’s already declining?
In many cases, yes—especially if the decline is caught early. Our arborists will evaluate the tree and recommend whether PHC or removal is the best option.
