Garlic Mustard Busting May 22, 2016

10:30 am to 12:30 pm

The High Park Stewards have been removing Garlic Mustard from a number of sites within the park for many years. Protocols on how best to control GM are changing all the time and we are always upgrading our skills.

We are able to notice a real positive effect from our work but there is still lots to do.

As many people as possible are needed as there is no end of this plant in High Park. Full Pingg Invite

Meet us in front of the Grenadier Restaurant at 10:30 am. Tools provided. Please bring water, a hat, and cover your arms and legs.

The Boulevard Beds group will also be working on our demonstration gardens located on the perimeter of the Grenadier Restaurant. A few people are needed to join them.

The Biodiversity and Education Awareness Network BEAN has excellent information on keeping this species from further damaging our forests.

Also see:



Garlic Mustard is an extremely aggressive invasive plant in woodland areas. Not only does it crowd out almost every other type of plant but is has an allelopathic agent that hinders their growth. Once removed native species can be planted to restore some biodiversity. Areas where GM has been removed need to be monitored and tended for at least 5 years as there is a strong seedbank and root system left behind.

Garlic Mustard can have very deep roots
removal early in the season is much easier
Garlic Mustard
yes, it does smell like garlic and mustard
