Garlic Mustard

Garlic Mustard

What is it?
Garlic mustard (Alliaria petiolata) is a fast-growing (biennial) herbaceous broadleaf weed from Europe, first reported from Long Island in 1868. This species is now a common invasive exotic. It is a habitat generalist occurring in agriculture, rights-of-way, and disturbed and undisturbed hardwood forests. It invades the understory of many woodland types and quickly carpets the forest floor.


How do I control it?
Effective control means reducing or hopefully eliminating garlic mustard plants with little impact to native cooccurring species. Because it is a biennial with seeds that remain viable for several years, control is required for a number of years. Hand pulling individual plants may be possible in the earliest stages of an invasion.
