Invasive Lily Removal on South Vancouver Island

Lilies are often planted for their showy blooms and low maintenance—but some lily species, especially tiger lily and ditch lily (daylily) varieties, have become invasive threats on South Vancouver Island. Once established, they spread aggressively through underground tubers and rhizomes, forming dense clumps that crowd out native plants and dominate gardens, roadsides, and wild spaces.

At Ascent Yard Care, we specialize in the professional removal of invasive lilies, combining manual extraction, mechanical root removal, and targeted herbicide application to ensure permanent eradication. As Vancouver Island’s top invasive plant removal company, we’ve restored hundreds of properties where ornamental lilies had taken over garden beds, pastures, and natural areas.

Why Invasive Lilies Are a Problem

While some cultivated lilies behave well in containers or carefully maintained beds, others—particularly wild-growing tiger lilies, daylilies, and hybrid ditch lilies—spread aggressively and resist traditional weeding or digging.

Problems caused by invasive lilies:

• Spread by underground tubers and rhizomes, making them hard to remove completely
• Form dense monocultures that prevent native plants or ornamentals from growing
• Re-grow vigorously after cutting, mowing, or shallow digging
• Difficult to control once established, especially in neglected gardens, rural properties, or trailsides
• Reduce ecological diversity, especially along streambanks and woodland edges

A few clumps of daylilies may seem manageable at first, but over time they can blanket entire slopes, garden beds, or forest edges—becoming a long-term nuisance.

Ascent Yard Care’s Invasive Lily Removal Process

Removing invasive lilies successfully requires going below the surface—cutting is not enough. Our team uses a proven, multi-step process tailored to each site’s layout, soil, and goals.

1. Site Assessment

We evaluate the size and density of the lily infestation and determine whether it’s spreading into gardens, forested areas, or naturalized zones. Our crew will identify the variety (e.g., daylily, tiger lily, or escaped ornamental) and develop a removal strategy that suits your landscape.

2. Manual or Mechanical Root Removal

We excavate lilies at the root, removing all tubers, rhizomes, and bulbs. This prevents the plant from re-sprouting. Depending on access and soil conditions, we use hand tools or light excavation equipment to ensure a thorough job.

3. Targeted Herbicide Treatment (Optional)

In areas with extensive rhizome networks or where full excavation isn’t possible, we offer selective herbicide application by certified professionals. These treatments are safe, effective, and designed to protect surrounding vegetation while eliminating regrowth.

4. Debris Removal & Landscape Restoration

All lily debris is removed off-site to prevent tuber fragments from re-rooting. We also offer site replanting, mulching, or native plant restoration to stabilize soil and prevent re-invasion.

5. Follow-Up Monitoring

We offer seasonal check-ins to monitor for regrowth and perform touch-up treatments if necessary—especially in wildland or naturalized areas where lilies may reappear over time.
