Garlic mustard (alliaria petiolata) is a harmless-looking menace that silently takes over the forest floor, much like buckthorn bullies the sub-canopy tier of the woods. In the spring to early summer, garlic mustard is flowering and developing seeds to spread before it dies at the end of its 2-year life. Chemicals can be used in the early spring and late fall, when it is the only green ground cover, and there is low risk of spraying desirable plants. Otherwise, the best control method is to uproot them by hand, destroy/dispose of the seed pods, and hang them, roots up, to dry out.
