Permanent Tansy Removal on South Vancouver Island

If you’ve noticed clusters of tall yellow-flowered plants taking over fields, fence lines, or road edges, you’re likely looking at common tansy (Tanacetum vulgare)—one of the most invasive and persistent weeds on South Vancouver Island.

Tansy spreads rapidly through both seed and rhizomes. It outcompetes native plants, takes over pastures and gardens, and is toxic to humans, pets, and livestock. Cutting it back or pulling it out usually just delays the problem. You need a professional strategy to remove it permanently.

At Ascent Yard Care, we provide complete tansy removal services using mechanical, ecological, and licensed herbicide-based strategies to safely eliminate it—root and all.

Why Tansy Is So Hard to Eliminate

• Rhizome root systems: Tansy spreads underground and regrows from root fragments.
• High seed production: Each plant can produce thousands of seeds per season.
• Toxic to animals and people: All parts of the plant are poisonous if ingested.
• Forms dense monocultures: Tansy chokes out grasses, native wildflowers, and crops.
• Highly resistant: Cutting or digging alone often fails—plants regrow stronger and thicker.

Our Proven Tansy Removal Process

1. On-Site Assessment

We inspect the size of the infestation, its proximity to desirable plants or animals, and the soil conditions. This helps us build a custom removal plan for your property.

2. Mechanical Cutback

We cut down the mature plants using commercial-grade trimmers and brush cutters, minimizing seed spread while prepping the site for root-level treatment.

3. Licensed Herbicide Application

We are fully licensed in British Columbia to apply herbicide, giving us the legal and technical ability to eliminate tansy at the root.

We use targeted, turf-safe or pasture-safe herbicides, applied via:

• Spot spraying
• Wicking for precision
• Stem injection in sensitive areas

This step is essential for permanent root death.

4. Soil Disturbance & Rhizome Removal

Where appropriate, we disturb and sift the soil to remove rhizomes and root fragments, especially in high-value planting beds or restoration zones.

5. Reseeding or Mulching

We restore the cleared area with competitive grasses, native plants, or mulch, depending on your land use goals. This prevents new infestations from taking hold.

6. Ongoing Monitoring & Follow-Up (Optional)

Tansy can return from seedbanks or adjacent properties. We offer scheduled monitoring or follow-up spot treatments for guaranteed long-term control.

This is critical. Tansy often requires chemical treatment for full eradication, and most landscaping companies aren’t licensed to apply it. We are—and we do it safely, selectively, and by regulation.

We Offer More Than One Solution

We understand that not all clients want herbicide—so we also provide manual, mechanical, and ecological methods, adapted to your property, goals, and values.
