Garlic Mustard

Weed of the Month: Garlic Mustard

Garlic mustard (Alliaria petiolata) is an increasingly invasive weed in our community.  Native to central and western Europe, this fast-growing plant commonly invades sites such as parks, trails, roadsides, and streamsides. April is a great time to manage this important invasive weed on your property.

When crushed, the leaves generally give off a strong garlic scent.  While it is true that this weed is edible, it is generally avoided by most grazing animals.   Adult plants form dense patches up to 3 feet in height at maturity.  The plant produces white four-petaled flowers in the spring and has kidney-shaped, deeply scalloped leaves.  It can grow in full sun to full shade, making it very adaptable to wherever its seed may land.

Garlic mustard can be very difficult to control due to the large number of seeds it produces.  Small patches can be controlled by pulling the adult plants before they begin to flower.  Once plants begin flowering, be sure to bag and dispose of the plants as trash.  Flowers from pulled plants CAN and WILL produce seed!  When pulling garlic mustard, be sure to remove the entire taproot to prevent re-sprouting.  Springtime is the best time to remove garlic mustard, while the soil is still soft from winter and spring rains.
