Managing invasive plants on your property

Our Invasive Plant Management Strategy explores preliminary options to help manage and control high risk invasive plants on private properties, but even without these protections, we can all still do our part to control the spread of invasive species:

  1. Spread the word to stop the spread — Active outreach and education among peer groups, garden clubs, and neighbourhood associations can help prevent the introduction of unwanted invasive species
  2. Know your landscape sources — Invasive plants can be introduced during garden installation and renovation or contaminated soils, fill and seed mixture
  3. Watch your neighbourhood — Early detection is key in successful treatment of invasive plants
  4. Stop dumping — Illegal dumping of yards trimmings and green waste can establish invasive plants along park edges and greenways. Responsible disposal of plant material is key to controlling the spread of invasive plants
  5. Handle with care —  Identify the most appropriate treatment techniques. The responsible use of chemical herbicides is of critical importance given the sensitive ecology within the District.

Safely disposing of invasive plants

Invasive species — with the exception of Giant Hogweed — can be combined with the rest of your yard trimmings and put out in your regular curbside organics collection. Please double bag any Giant Hogweed and throw it in your garbage.
