A friendly reminder not to dump your yard waste in Oakville’s greenspaces and woodlands!

We’ve been seeing this at a few of our sites this summer. Dumping yard waste is a bad idea because it can spread invasive species and harm native forest plants.

Instead you can try:

  • Recycling as much as possible
  • Composting yard waste

July 5th Corporate Greening Day:

This week 10 more volunteers from AmerisourceBergen joined us for their Corporate Greening Day. They were back at Bronte Bluffs Park pulling more garlic mustard. They pulled a total of 30 bags full of the invasive plant!


 Do you have garlic mustard on your property? Here are some tips for how to remove it:

  • Hand pull plants by pulling from as close to the ground as possible

    Garlic mustard at Bronte Bluffs Park is almost as tall as our Urban Forest Stewardship Coordinator.
  • Place pulled plants in garbage bags for disposal and tie shut. Why not yard waste bags or compost? Because garlic mustard can still seed even after it has been pulled so composting it will transport its seeds… it basically can come back from the dead.
  • After placing in garbage bags leave the sun for a couple days, then it’ll be ready to be disposed of.

If you’re interested in learning more about garlic mustard and other invasive species Oakvillegreen and P.O.W.E.R (Protect Our Water and Environmental Resources) are hosting an invasive species workshop on July 16th. For more info you can visit the event page or email
