How do I know if my tree needs a health care program?

Common signs include thinning canopy, early leaf drop, unusual discoloration, dieback at branch tips, or visible pest activity. Trees in compacted soils, near construction, or under prolonged stress are good candidates. An arborist walk-through will identify what is actually limiting the tree before recommending any treatment.

What is deep root fertilization and does it actually work?

Deep root fertilization delivers nutrients and soil amendments directly into the root zone under pressure, bypassing compacted surface soils. It works best when paired with a soil assessment — throwing fertilizer at a tree with compacted or anaerobic soil often does little. We assess first and recommend treatment only when the soil data supports it.

Do you treat for emerald ash borer under plant health care?

Yes. EAB trunk injection and soil drench treatments are part of our health care offerings. The key decision is whether your ash tree is worth treating — canopy decline beyond roughly 50% typically makes treatment uneconomical.

Are your pesticide applicators licensed in Ohio?

Yes. Ohio requires a pesticide applicator license for anyone applying pesticides commercially. Our staff hold Ohio licensed pesticide applicator credentials for all treatments we perform.

Can you treat a tree that another company already treated?

Yes. We will want to know what was applied and when before making recommendations. Some treatments have re-application windows, and certain combinations can cause phytotoxic reactions — chemical stress that damages the tree rather than helping it. If the previous company used growth regulators or trunk injections, that is especially important to know. Bring any paperwork from previous treatments if you have it.

Plant Health Care Columbus Ohio | Arborist Solutions

Keeping trees healthy requires more than pruning. Soil quality, root zone conditions, pest pressure, and structural stress all affect long-term vitality. Our approach is grounded in a simple idea: healthy trees grow in healthy soil. We work to replicate the conditions of a forest floor in residential settings — improving organic matter, soil biology, aeration, and drainage so trees can do what they naturally do when the soil supports them.

Proactive Approach

Our arborists are dedicated to extending the life of your trees through soil amendments, structural support systems, and tailored treatments. We work to preserve tree health and longevity for decades to come.

Common Problems We Address

Soil compaction — Air spade treatment loosens the root zone without damaging feeder roots.
Nutrient deficiencies — Deep root fertilization delivers nutrients directly to the root zone.
Pest and disease pressure — Early identification and treatment of anthracnose, apple scab, scale, and more.
Girdling roots — Roots that wrap the base of the trunk and slowly restrict vascular flow.
