Quadra Island’s lush forests and coastal gardens make it a paradise for homeowners—until invasive knotweed (Fallopia spp.) starts to take over. Left unchecked, this aggressive plant can damage foundations, out‑compete native flora, and cost thousands in remediation. At Ascent Yard Care, we’ve been mastering invasive‑plant eradication since 2017, trusted by the City of Victoria, the City of Langley, and thousands of residential clients across Vancouver Island and the Lower Mainland.

Below is our 7‑point listicle that outlines a complete, science‑backed knotweed removal strategy tailored to Quadra Island’s unique climate and soil conditions. Follow each step and you’ll protect your property, preserve local biodiversity, and avoid costly repeat treatments.

1️⃣ Identify the Knotweed Species & Map Its Extent

Why it matters: Quadra Island hosts both Japanese knotweed and Giant knotweed, each with slightly different growth habits. Accurate identification prevents wasted herbicide and ensures regulatory compliance.

Action: Walk the property in early spring when shoots are 30‑45 cm tall. Look for hollow, bamboo‑like stems with distinct nodes and heart‑shaped leaves.
Tool: Use a simple GPS or a free mapping app to outline the infestation boundaries.
Local tip: The island’s salty sea breeze can stunt growth, so even a small patch may hide a larger underground rhizome network.

2️⃣ Conduct a Soil & Site Assessment

Why it matters: Knotweed thrives in disturbed, moist soils common near Quadra’s creek valleys and coastal bluffs. Understanding soil pH and moisture helps select the most effective herbicide formulation.

Action: Collect soil samples from three spots within the mapped area. Test for pH (ideal 6.0‑7.5) and organic matter.
Result: Adjust the herbicide mix (e.g., adding a surfactant) to improve uptake on the island’s slightly acidic coastal soils.

3️⃣ Choose an Eco‑Friendly, Targeted Herbicide

Why it matters: Ascent Yard Care uses EPA‑approved, low‑toxicity systemic herbicides that travel to the roots without harming surrounding plants, wildlife, or pollinators—crucial for Quadra’s sensitive marine ecosystem.

Action: Apply a glyphosate‑based product at 2 % concentration during the plant’s active growth phase (late May‑early June).
Safety: Our crew wears certified PPE, and we follow BC’s Integrated Pest Management (IPM) guidelines to protect local fauna.

4️⃣ Execute Precision Application

Why it matters: Over‑spraying can damage native grasses and affect nearby watercourses. Precision ensures the herbicide reaches only the knotweed stems.

Action: Use a hand‑held, low‑drift sprayer with a 0.5 mm nozzle, aiming at the stem base. Apply a thin, even coat—no more than 0.5 ml per stem.
Timing: Early morning or late afternoon when wind speeds are below 5 km/h reduces drift risk.

5️⃣ Monitor Growth and Document Results

Why it matters: Knotweed can re‑sprout from residual rhizomes. A 30‑day monitoring window lets us verify treatment success and triggers our free second‑treatment guarantee.

Action: Inspect the site weekly. Mark any new shoots with colored flags.
Record: Take photos and update your GIS map. This data helps us fine‑tune future applications and provides proof for municipal compliance.

6️⃣ Implement Follow‑Up Treatment (If Needed) – Free of Charge

Why it matters: Our 30‑day guarantee means if any knotweed is still alive after the first application, we return for a second treatment at no extra cost. This eliminates the guesswork for homeowners and demonstrates our confidence.

Action: Contact Jake directly through the free‑quote form below. We’ll schedule a follow‑up visit, re‑apply the herbicide, and reassess the site.
Benefit: You receive complete eradication without hidden fees—peace of mind for Quadra Island residents.

7️⃣ Restore the Landscape with Native Plantings

Why it matters: Re‑establishing native vegetation reduces the chance of re‑invasion and supports local wildlife, especially the island’s bird and butterfly populations.

Action: After confirming dead knotweed (usually 4‑6 weeks post‑treatment), amend the soil with organic compost.
Plant: Choose coastal‑adapted natives like Salal (Gaultheria shallon), Red‑osier Dogwood (Cornus sericea), or Pacific Yew (Taxus brevifolia).
Local tip: Planting near the Quadra Island Marine Park edges helps stabilize soil and preserves the natural shoreline.
