Understanding Knotweed: The Agassiz Challenge

Species and Identification

The two most common invasive species in the Fraser Valley are Japanese knotweed (Fallopia japonica) and Giant knotweed (Fallopia sachalinensis). Both share recognizable traits:

• Cylindrical, hollow stems with distinct nodes (often described as “bamboo‑like”).
• Large, heart‑shaped leaves that emerge in late spring.
• Clusters of tiny white flowers in late summer.

In Agassiz’s mixed‑soil conditions, these plants can reach up to 3 m (10 ft) in height, forming dense thickets that spread via rhizomes and root fragments.

Why Knotweed Is a Threat

• Structural Damage: Rhizomes exert pressure on foundations, sidewalks, and drainage pipes, leading to cracks and costly repairs.
• Ecological Disruption: Knotweed outcompetes native grasses and shrubs, reducing biodiversity and altering soil chemistry.
• Legal Liability: Under British Columbia’s Invasive Species Act, property owners are obligated to control knotweed on their land. Failure to act can result in fines and enforcement orders.

The Regulatory Landscape in Agassiz and British Columbia

British Columbia treats knotweed as a regulated invasive species. The Provincial Invasive Species Regulations require:

1. Identification and Reporting: Any suspected knotweed must be reported to the BC Ministry of Forests within 30 days.
2. Control Measures: Landowners must implement an effective control plan approved by a qualified professional.
3. Disposal: Plant material must be disposed of at an approved landfill or incinerated; simply composting or dumping on site is prohibited.

Agassiz’s municipal bylaws echo these provincial requirements, adding local inspection procedures for larger infestations. Working with a licensed provider like Ascent Yard Care ensures full compliance, avoiding penalties and protecting community ecosystems.

Ascent Yard Care’s Comprehensive Knotweed Removal Process

Step 1: Site Assessment and Client Consultation

Every successful removal begins with a detailed site audit. Jake Innes, a certified arborist, evaluates:

• Species identification and infestation extent.
• Soil type, moisture levels, and proximity to structures.
• Seasonal growth stage (critical for timing).

During the consultation, we discuss client goals, budget constraints, and any property‑specific concerns (e.g., heritage trees, irrigation systems). This personalized approach guarantees that the control plan aligns with both ecological and business objectives.

Step 2: Integrated Control Strategies

We employ an integrated pest management (IPM) framework that blends mechanical, chemical, and, when appropriate, biological methods:

• Mechanical Removal: For small, isolated patches, we use hand‑pulling combined with root excavation. This technique is labor‑intensive but eliminates the need for herbicides.
• Targeted Herbicide Application: When infestations exceed 5 m², we apply Systemic glyphosate (registered for knotweed control) directly to the stems using a low‑drift sprayer. The timing—late summer when the plant is storing nutrients in its rhizomes—is crucial for maximum uptake.
• Soil Solarization (Seasonal Option): In the hottest months (July‑August), we cover cleared areas with clear polyethylene to heat the soil, reducing viable rhizome fragments.

Step 3: Safe Disposal and Compliance

All harvested plant material is sealed in double‑lined bags and transported to a licensed BC landfill. We provide the client with a disposal receipt—a required document for municipal inspection.

Step 4: Monitoring and After‑care

Knotweed can regrow from a single rhizome fragment. We schedule quarterly monitoring visits for the first two years, during which we:

• Inspect for new shoots.
• Apply spot‑treatments if needed.
• Advise on soil restoration (e.g., native grass seeding) to suppress re‑colonization.

Seasonal Timing: When Is the Best Time to Treat Knotweed in Agassiz?

Agassiz’s continental climate—warm, dry summers and cold, wet winters—creates distinct windows for optimal control:

Season	Recommended Action	Reason
Late Spring (May‑June)	Early mechanical removal of visible shoots	Rhizomes are still shallow; easier excavation
Late Summer (July‑August)	Systemic herbicide application	Plant stores nutrients in roots, enhancing herbicide translocation
Early Fall (September)	Soil solarization & follow‑up monitoring	Warm soil retains heat longer, killing residual fragments
Winter	No active treatment; focus on preventive planning for spring	Ground is frozen; mechanical work is impractical

Timing treatments to these windows reduces chemical usage, improves efficacy, and aligns with regulatory expectations for prompt control.

Cost Estimates: What Homeowners Can Expect

While each site is unique, our transparent pricing model provides a reliable baseline:

Service	Approximate Cost (CAD)	Notes
Small Mechanical Removal (<5 m²)	$250‑$400	Includes labor, root excavation, and disposal
Medium Chemical Treatment (5‑20 m²)	$600‑$1,200	Herbicide, application, disposal, and 1‑year monitoring
Large Integrated Program (>20 m²)	$1,500‑$3,500+	Full IPM package, multiple visits, after‑care soil restoration
Annual Monitoring (per visit)	$150‑$250	Quarterly checks, spot‑treatment, reporting

All estimates are provided free of charge after the initial site assessment. No hidden fees—just a clear, business‑oriented proposal that respects your budget.
