Why Tree Health Matters
When a tree begins to decline, it can become a hazard to your home and property. Early detection of disease, pests, or soil stress allows us to take corrective action before damage occurs.
Common signs your tree may need attention:
Yellowing or browning leaves
Fungal growth or cankers on the trunk
Branch dieback or thinning canopy
Sawdust or holes from insects
Leaning trunk or exposed roots after storms
Why Preservation Comes First
Our approach is to restore and protect whenever possible. We only recommend removal when it’s the safest or best option. Each plan focuses on minimal disturbance, natural recovery, and long‑term vitality.
Our Process
Every tree and site is different, so we adapt our process based on your property’s unique conditions.
Assessment: On‑site inspection by an ISA‑certified arborist.
Diagnosis: Identify pests, diseases, soil issues, or structural concerns.
Plan: Provide clear recommendations with photos and timelines.
Treatment: Apply targeted pruning, soil care, or cabling/bracing if needed.
Aftercare: Offer guidance for watering, mulching, and ongoing monitoring.

FAQ — Tree Health
-
Every 2–3 years is ideal for most mature trees. Younger or high-risk trees (near structures or roads) may benefit from annual assessments.
-
In many cases, yes — early treatment through pruning, soil improvement, and pest management can restore health and stability. Removal is only a last resort.
-
Black knot (chokecherry, mayday), fire blight (crabapple), cytospora canker (spruce), and Dutch elm disease are the most common local issues. Our arborists know how to diagnose and manage each safely.
-
Only when necessary. We prioritize organic soil care, pruning, and sanitation methods before any targeted treatments are applied.
-
Dormant season (late fall to early spring) is the best time for most pruning and treatments, especially elm trees, which must be pruned between October and March by bylaw.
