Tree Line Plant Health Care, LLC
Keep Your Trees Healthy—Before Problems Get Expensive
Healthy trees don’t happen by accident.
Tree Line’s NEW Plant Health Care (PHC) services are designed to protect your trees and shrubs from pests, disease, and decline—before minor issues turn into major removals.
Our approach is proactive, science-based, and targeted. No blanket spraying. No unnecessary treatments. Just smart care that keeps your landscape strong and thriving.
What Is Plant Health Care?
Plant Health Care is a preventive approach to tree and shrub care that focuses on long-term health rather than short-term fixes.
PHC helps by:
-
Detecting pests and disease early
-
Improving soil and root health
-
Strengthening trees against environmental stress
-
Reducing the need for costly removals
Instead of reacting after a tree starts failing, PHC helps extend the life, safety, and appearance of the trees you already have.

We provide Plant Health Care for residential and commercial properties throughout New Hampshire.
We commonly address:

Our Approach: Smart, Targeted, Responsible
We don’t spray first and ask questions later.
Tree Line follows Integrated Pest Management (IPM) principles, which means:
-
Proper identification before treatment
-
Cultural and mechanical solutions when possible
-
Targeted, low-risk treatments only when necessary
-
Ongoing monitoring and follow-ups
This approach is safer for your family, pets, beneficial insects, and the environment—and more effective long term.
