Introduction – Why Knotweed Is a Serious Threat in Chilliwack

Knotweed (especially Japanese knotweed Fallopia japonica) is one of the most aggressive invasive plants in the Lower Mainland and on Vancouver Island. Its rhizome network can extend up to 3 m underground, allowing it to:

Outcompete native vegetation and reduce biodiversity.
Damage foundations, sidewalks, and drainage systems by forcing cracks as the stems thicken.
Lower property values—many real‑estate transactions in Chilliwack now require a professional knotweed assessment.

For homeowners, landscapers, and municipal crews, the key question is: How can knotweed be removed safely, permanently, and without harming surrounding plants or wildlife?

Ascent Yard Care answers that question with a proven, eco‑friendly methodology that combines targeted herbicide application, scientific monitoring, and an industry‑leading guarantee.

1. Understanding Knotweed Biology – The Science Behind Effective Eradication

Characteristic	Why It Matters for Removal
Rhizome depth – up to 3 m	Surface treatments alone are insufficient; systemic herbicides must travel down the rhizome.
Rapid growth – up to 1 m per season	Early detection is crucial; a small patch can become a full‑scale infestation within a single growing season.
Resilience to mechanical removal – stems re‑sprout from any fragment	Cutting or digging without proper herbicide treatment often spreads the plant further.
Seasonal herbicide uptake – best in late summer/early fall	Leaves are mature, translocation to roots is maximized, improving kill rates.

Jake Innes, a certified arborist and owner of Ascent Yard Care, leverages this knowledge to time treatments perfectly for Chilliwack’s climate (wet winters, dry summers).

2. Our Comprehensive Knotweed Removal Process – Step‑by‑Step

Step 1 – Site Evaluation & Mapping

Visual inspection – Identify stems, leaf patterns, and crown clusters.
Soil probe test – Confirm rhizome depth using a thin auger.
GIS mapping – Create a digital map of the infestation to track treatment zones.

Local tip: In Chilliwack’s Sumas Prairie, high water tables can push rhizomes closer to the surface, making detection easier but also increasing the risk of spread during heavy rains.

Step 2 – Pre‑Treatment Preparation

Mark non‑target vegetation with biodegradable flags to protect desirable plants.
Remove debris (fallen leaves, mulch) that could shield the herbicide.
Notify neighbors about the upcoming treatment; our herbicide is EPA‑approved and non‑drift, but transparency builds community trust.

Step 3 – Targeted Herbicide Application

We use glyphosate‑based systemic herbicides formulated for invasive plant control, applied with a low‑volume, pressure‑spray wand that delivers 0.5 L per minute.

Application window: Late July to early September (optimal leaf maturity).
Coverage: Each stem is coated until the herbicide runs off (≈ 2 seconds per stem).
Safety measures: Protective gloves, goggles, and a wind‑speed check (< 5 km/h) to prevent drift.

Our formula is eco‑friendly: it breaks down within 30 days, leaving no residual toxicity for surrounding flora, fauna, or soil microbes.

Step 4 – Post‑Application Monitoring (30‑Day Observation)

Weekly site visits for the first two weeks to assess visual die‑back.
Root sampling at day 15 to verify systemic translocation.
Digital photo log for client transparency.

If any knotweed remains viable after 30 days, a second treatment is provided free of charge—the Ascent Yard Care guarantee that sets us apart.

Step 5 – Final Site Restoration

Rhizome excavation (if required) – only after the plant is dead, to prevent future resurgence.
Soil amendment – add compost or native seed mix to restore ecological balance.
Landscape design consultation – Jake’s arborist expertise can suggest native alternatives that thrive in Chilliwack’s climate.

4. Frequently Asked Questions (FAQ) – Knotweed in Chilliwack

Q1: How long does it take to completely eradicate knotweed?
Answer: Most sites see 80‑90 % die‑back within 2–3 weeks. Full eradication (including rhizome removal) typically finishes within 8 weeks, depending on infestation size.

Q2: Will the herbicide affect my garden vegetables?
Answer: No. Our low‑drift application targets only the knotweed stems. Non‑target plants are shielded, and the herbicide degrades quickly, leaving no residue that could be taken up by edible crops.

Q3: Is knotweed removal covered by my homeowner’s insurance?
Answer: While some policies may cover invasive plant removal, our $5 million liability insurance protects you from any accidental damage during treatment.

Q4: Can I do it myself?
Answer: DIY methods often spread the plant further and may violate local bylaws. Professional treatment ensures compliance with Chilliwack’s invasive species regulations and provides the guarantee of a second treatment if needed.

Q5: What time of year is best for treatment in Chilliwack?
Answer: Late summer (July–September) is optimal because the plant’s leaves are mature, maximizing herbicide uptake.

5. Local Insights – Knotweed Hotspots in Chilliwack

Sumas Prairie: The flat, wet soils create a perfect environment for knotweed to thrive along irrigation ditches.
West Side of the City (near the Fraser River): Frequent flooding carries rhizome fragments downstream, establishing new colonies.
Residential lawns near the Chilliwack River: Homeowners often notice rapid stem growth after spring rains; early detection is key.

If you spot a “bamboo‑like” plant with heart‑shaped leaves and hollow, jointed stems, it’s likely knotweed. Contact Ascent Yard Care immediately—early intervention reduces treatment cycles and costs.

6. The Economic Impact – Why Prompt Removal Saves Money

Property value: A clean, knotweed‑free lot can increase market price by up to 5 % in the Fraser Valley.
Repair costs: Unchecked rhizomes can push up against foundations, leading to $2,000–$5,000 in structural repairs.
Municipal fines: Chilliwack’s bylaws may impose penalties of $500–$2,000 for uncontrolled invasive species.

Investing in professional removal now prevents these downstream expenses.
