Why Tree of Heaven Is a Problem in Duncan?
Tree of Heaven (Ailanthus altissima) is an aggressive, non‑native invasive species that thrives in the mild, maritime climate of Vancouver Island and the Lower Mainland. In Duncan, its presence is especially concerning because:
| Issue | Impact on Duncan |
|---|---|
| Rapid Growth | Can reach 30 m in height, out‑competing native trees such as Douglas‑fir and Western red‑cedar. |
| Allelopathy | Releases chemicals that suppress germination of native seedlings, reducing biodiversity in local parks and residential yards. |
| Structural Hazard | Weak, brittle wood often leads to sudden limb breakage—dangerous near sidewalks, schools, and the Cowichan River trail. |
| Fire Risk | High oil content in bark and leaves makes it more flammable, a concern for the dry summer months. |
| Legal Liability | Municipal bylaws in Duncan and the Cowichan Valley Regional District require property owners to manage invasive species on their land. |
Understanding these risks underscores why early detection and professional removal are essential.
Legal & Environmental Considerations in the Cowichan Valley
- Municipal Bylaws: Duncan’s “Invasive Plant Management Bylaw” mandates removal of species listed under the BC Invasive Species Council, including Tree of Heaven. Failure to comply can result in fines or municipal remediation charges.
- Provincial Regulations: The Invasive Species Act (BC) requires that herbicide applications follow the Integrated Pest Management (IPM) guidelines to protect waterways like the Cowichan River.
- Ecological Sensitivity: Many neighborhoods border riparian zones; improper herbicide use can affect salmon habitat. Ascent Yard Care’s protocols are designed to protect these sensitive ecosystems.
How Ascent Yard Care Identifies Tree of Heaven
- Leaf Shape – Pinnately compound leaves with 10–30 leaflets, each leaflet having a distinct, glossy, and slightly serrated edge.
- Smell – When crushed, leaves emit a strong, “peppery” odor.
- Bark – Gray‑brown, ridged bark with a flaky texture.
- Fruit – Small, winged samaras that disperse widely in the wind.
- Growth Pattern – Often found in disturbed soils—along sidewalks, utility corridors, and near construction sites.
Our certified arborist, Jake Innes, uses these visual cues combined with a GPS‑enabled mapping system to log every Tree of Heaven location for precise treatment planning.
Step‑by‑Step Tree of Heaven Removal Process
1. Site Assessment & Mapping
- Walk‑through inspection: Jake evaluates tree size, root spread, and proximity to structures or water bodies.
- Digital mapping: Records exact coordinates, creating a treatment map for follow‑up.
2. Treatment Planning
- Method selection: Options include cut‑and‑treat, basal bark application, or stem injection—chosen based on tree size and site constraints.
- Safety briefing: Discusses protective gear, traffic control (if near streets), and wildlife considerations.
3. Mechanical Removal (If Feasible)
- Selective pruning: Reduces canopy to improve herbicide penetration.
- Stump grinding: For trees under 2 m DBH, a grinder removes the stump to <2 cm, preventing resprouting.
4. Targeted Herbicide Application
- Active ingredient: Glyphosate (Roundup® Pro) or Triclopyr (Garlon®) at EPA‑approved concentrations.
- Application technique:
- Basal bark: Paint directly onto the lower 12‑18 inches of the trunk.
- Stem injection: Inject into the sap flow for larger trees (>30 cm DBH).
- Eco‑friendly safeguards: Use low‑drift sprayers, apply during calm weather (<5 km/h wind), and employ biodegradable carrier agents to minimize runoff.
5. Post‑Application Monitoring (30‑Day Guarantee)
- Inspection: At 30 days, Ascent Yard Care verifies plant mortality.
- Free second treatment: If any Tree of Heaven remains viable, we provide a second application at no extra cost.
6. Site Restoration
- Soil amendment: Apply organic compost to restore soil health.
- Native planting: Recommend local species (e.g., Salix interior or Arbutus menziesii) to outcompete any remaining seedlings.
Eco‑Friendly Herbicide Application & Safety Protocols
- Certified applicators: All crew members hold BC Ministry of Environment pesticide license.
- Buffer zones: Minimum 5 m from water bodies, increased to 10 m near the Cowichan River.
- Personal protective equipment (PPE): Gloves, goggles, and respirators are mandatory.
- Training: Continuous education on Integrated Pest Management (IPM) and best practices for pollinator protection.
Our approach kills the target Tree of Heaven while leaving surrounding plants, beneficial insects, and wildlife unharmed—a claim backed by independent field trials.
Post‑Treatment Monitoring & Maintenance
| Timeline | Action |
|---|---|
| Day 0–7 | Visual check for herbicide drift; document any weather anomalies. |
| Day 14 | Inspect for early signs of resprouting; apply spot‑treatment if needed. |
| Day 30 | Comprehensive evaluation; guarantee enforcement. |
| Month 3–6 | Soil health assessment; recommend mulching and native re‑planting. |
| Yearly | Follow‑up visit to ensure no new Tree of Heaven seedlings have emerged. |
Regular monitoring reduces the chance of re‑infestation and supports long‑term ecosystem health.
Frequently Asked Questions (FAQ)
Q1. How long does it take for a Tree of Heaven to die after treatment?
Answer: Most trees show wilting within 7‑10 days; complete die‑back occurs within 4‑6 weeks. Our 30‑day guarantee ensures you see full results.
Q2. Will the herbicide affect my garden vegetables or fruit trees?
Answer: No. Basal bark and stem injection methods limit movement to the target tree only. Non‑target plants remain safe.
Q3. Is Tree of Heaven removal covered under my homeowner’s insurance?
Answer: Many policies cover invasive species removal if it’s required by municipal bylaws. Ascent Yard Care provides a detailed invoice and documentation for insurance claims.
Q4. Can I do the removal myself?
Answer: DIY removal often leads to incomplete eradication and legal non‑compliance. Professional treatment guarantees effectiveness and liability protection.
Q5. What makes Ascent Yard Care different from other landscaping companies?
Answer: We combine arborist expertise, science‑backed herbicide protocols, five‑million‑dollar liability insurance, WCB coverage, and a 30‑day free‑treatment guarantee—all trusted by the City of Victoria and City of Langley.
Local Tips for Homeowners in Duncan
- Inspect after construction – Tree of Heaven often colonizes disturbed soil near new builds on St. John’s Road or Duncan Highway 1. Early detection prevents spread.
- Use mulches wisely – Cedar mulch can suppress seed germination; however, avoid piling mulch against tree trunks to prevent fungal issues.
- Water wisely – Over‑watering near riverbanks can create ideal conditions for seedlings. Aim for deep, infrequent watering.
- Community cooperation – Join the Duncan Invasive Species Working Group to stay informed about city‑wide eradication initiatives.
- Seasonal timing – The optimal window for herbicide application is late spring to early summer when the tree’s sap flow is strongest.
