Dedicated to Protecting Trees

Greenshield Tree Health was created to help homeowners protect valuable trees from insects, drought stress, poor soils, and preventable decline. The company focuses on practical diagnosis, targeted treatment, and honest guidance about whether a tree can be helped.

Targeted Delivery

Material goes directly into the tree's vascular system, reaching the tissues that need it. Therefore, less material is needed compared to broadcast applications, largely eliminating harm to non-targeted pests. Injections can be at any time of year, but we avoid the coldest months.

For many tree health issues, trunk injection delivers treatment directly into the tree. This approach can reduce waste, limit exposure outside the tree, and provide targeted support where it's needed most.

We Want You To Become More ‘Tree Aware'

Quickly categorize all your local trees.

  • Stage 1=seems fine, no apparent problems.
  • Stage 2=a problem has surfaced
  • Stage 3=The problem has progressed and you know you need to swing into action.
  • Stage 4=Likely too late to save it
  • Stage 5=dead or will be soon.

If we can treat before mid-Stage 3 the tree has a good chance of surviving. Start noticing, you will quickly be able to discern the different stages.

No Drift

With Trunk injection there is no drift onto nontarget plants. The tree will grow out and around the plugs that have been left in place.

Injected treatments most often provide extended protection through the growing season. In fact, some treatments are only necessary every other year.

Micronutrient Injections

Injected treatments can provide extended protection through the growing season. Micronutrient injections typically last 2-3 years.

Trunk injection is not a solution for every tree or condition. A professional assessment determines whether it's appropriate for your situation.
