Garlic mustard can be pulled or cut, as well. Plants need to be bagged and removed as they produce allopathic chemicals that will continue to suppress native plants if the dead garlic mustard is left not he ground. The other reason for bagging and removing garlic mustard is that plants that have flowered will use their remaining nutrients to produce mature seed even after the plant is pulled.
Folks who live in southeastern Wisconsin can participate in 2017 Garlic Mustard Pull-A-thon. Sponsored by the Southeastern Wisconsin Invasive Species Consortium, Inc. (SEWISC), it is an annual fundraiser event, that encourages youth and adults throughout southeastern Wisconsin to protect their woodlands by pulling this invasive plant. The goal this year is to pull 10,000 pounds and raise essential funds for the fight against invasive species!
