Introduction

When a homeowner in Colwood opened a backyard gate last spring, they expected the familiar scent of pine and the soft rustle of native ferns. Instead, a thick, bamboo‑like stalk thrust through the soil, its emerald leaves forming an impenetrable wall. The culprit? Japanese knotweed (Fallopia japonica), an invasive species that has turned many of the region’s gardens into battlefields.

For residents of Colwood—a community framed by the Pacific Ocean, the Sooke Hills, and a growing suburban footprint—knotweed is more than an eyesore. It threatens property values, destabilizes soil, and can even jeopardize municipal infrastructure. The stakes are high, and the solution is rarely simple.

Enter Ascent Yard Care, a Vancouver Island‑based landscaping firm that has, since 2017, paired rigorous scientific methods with an on‑the‑ground understanding of British Columbia’s ecosystems. Under the stewardship of certified arborist Jake Innes, the company has become a go‑to resource for “knotweed removal in Colwood” and “knotweed removal services Colwood.” This investigative look reveals how Ascent Yard Care’s comprehensive approach not only eradicates the invasive plant but also safeguards the surrounding environment and community.

The Hidden Threat of Knotweed in Colwood

A Plant That Outsmarts the Landscape

Japanese knotweed was first introduced to Canada in the late 1800s as an ornamental garden plant. Its reputation for rapid growth—up to 10 cm per day—has earned it the moniker “the plant that never dies.” The species spreads via rhizomes that can extend three meters underground, re‑sprouting even after aggressive mechanical removal.

According to a 2022 report from the British Columbia Ministry of Forests, knotweed now occupies over 8,000 hectares across the province, with the Greater Victoria area accounting for roughly 12 percent of that total. In Colwood, the problem is amplified by the city’s mix of mature residential lots and newly developed subdivisions, which provide both the disturbed soil and the irrigation that knotweed loves.

Economic and Environmental Costs

The ramifications are tangible. A 2021 study by the University of British Columbia estimated that invasive plant control costs municipal governments $30 million annually nationwide. For a homeowner, knotweed can devalue a property by up to 15 percent if left unchecked, as lenders often view the infestation as a risk to structural integrity.

Ecologically, knotweed forms dense monocultures that outcompete native flora, reducing biodiversity and altering pollinator pathways. Its aggressive root system can infiltrate drainage pipes, leading to costly repairs.

How Ascent Yard Care Tackles Knotweed

A Tailored, Science‑Based Protocol

Ascent Yard Care’s knotweed removal service is not a one‑size‑fits‑all spray job. Instead, the process begins with a site‑specific assessment conducted by Jake Innes, whose arborist credentials ensure a deep understanding of plant biology and ecosystem dynamics.

Mapping the Infestation – Using GPS‑enabled tablets, the crew documents every visible stand and, crucially, estimates the underground rhizome network.
Soil Testing – Samples are sent to a certified lab to determine pH, organic matter, and potential herbicide interactions, guaranteeing that the chosen treatment will be both effective and environmentally responsible.
Targeted Herbicide Application – The company employs a low‑volume, systemic herbicide (typically glyphosate‑based, but formulated to meet BC’s strict environmental standards). The active ingredient is absorbed through the foliage and travels to the rhizomes, killing the plant from within without harming neighboring vegetation.

Eco‑Friendly Yet Effective

While the term “herbicide” can raise concerns, Ascent Yard Care’s approach mitigates risk. The herbicide is applied only to the knotweed foliage, using shielded sprayers that prevent drift. The formula biodegrades within weeks, and the company follows the Integrated Pest Management (IPM) guidelines advocated by the BC Ministry of Environment.

The Science Behind Targeted Herbicide

Systemic herbicides work by mimicking plant hormones, disrupting the plant’s ability to transport nutrients. When applied to mature knotweed leaves, the chemical travels down to the root crown, where it interferes with cell division. Because knotweed’s rhizomes are the primary means of spread, destroying them eliminates future shoots.

Research published in Weed Science (2023) confirms that a single, correctly timed application can achieve up to 95 percent kill rates in mature stands. Ascent Yard Care aligns its treatment schedule with the plant’s phenology—applying in late summer when the foliage is fully expanded but before the plant diverts resources to rhizome growth.

Guarantees and Accountability

The 30‑Day Free‑Second‑Treatment Promise

Confidence in the method translates into a bold guarantee: if any knotweed remains alive 30 days after the initial application, Ascent Yard Care will return for a second treatment at no extra charge. This promise is backed by internal monitoring—technicians revisit sites, document regrowth, and adjust herbicide concentration as needed.

Insurance and Professional Standards

Clients can also rest easy knowing the company carries five million dollars of liability insurance, adheres to WorkSafeBC coverage, and complies with all provincial regulations. These safeguards protect homeowners from accidental damage and ensure that all work meets the highest safety standards.

Local Insight: Colwood’s Unique Landscape

Colwood’s climate—mild, maritime, with an average annual precipitation of 1,200 mm—creates ideal conditions for knotweed’s aggressive growth. The city’s south‑west facing slopes, common in neighborhoods like Colwood Harbour and the Willowbrook subdivision, receive ample sunlight, accelerating the plant’s photosynthetic rate.

Moreover, recent municipal projects, such as the expansion of the Colwood Recreation Centre, have disturbed soil in several peripheral lots, inadvertently providing new footholds for knotweed. The City of Victoria and the City of Langley have both contracted Ascent Yard Care for large‑scale invasive plant eradication, citing the firm’s proven track record and its ability to work within tight municipal timelines.

Practical Tips for Homeowners

Early Detection – Look for bamboo‑like stems, heart‑shaped leaves, and hollow canes. Spotting knotweed in its early growth stage (first year) drastically reduces treatment cost.
Avoid DIY Cutting – Cutting knotweed without proper herbicide treatment often leads to regrowth. The plant stores energy in its rhizomes, which can sprout new shoots after the top is removed.
Maintain Healthy Soil – A robust native plant community can outcompete knotweed. Consider planting deep‑rooted natives like red‑osier dogwood (Cornus sericea) or coastal strawberry (Fragaria chiloensis) after removal.
Report Municipal Infestations – If you suspect knotweed on public land, inform the City of Colwood’s Parks and Recreation department. Early municipal intervention can prevent spread to private properties.
Schedule Professional Assessment – A qualified arborist, such as Jake Innes, can differentiate knotweed from look‑alikes (e.g., giant horsetail) and design a treatment plan that protects surrounding flora and fauna.
