Garlic Mustard

Garlic mustard is a biennial plant growing a basal rosette the first year, and a flowering stalk the second year. Flowers are small and white with 4 petals. When crushed, the leaves smell like garlic. This invader can grow in shade or sun and is a prolific seed producer. Seeds can be easily spread on boots, vehicles, animals and water. Garlic mustard grows successfully in a variety of conditions and soil types, easily outcompeting native vegetation. Control methods include both hand pulling and herbicide application. If pulling by hand, be sure to get all of the root. Plants should be bagged and discarded in the trash or landfill. Be sure to clean your boots and clothing well to avoid spreading seeds. After removing or spraying garlic mustard, you can mulch or re-seed the site with a fast-growing grass seed mix. Continue to monitor the area for new plants for several years.
