Japangrass (Microstegium vimineum) is a nonnative, invasive annual grass that is capable of overtaking forest understories in eastern U.S. forests. Fire is one tool that can be used to manage Japangrass. Fire prescriptions to control Japangrass include burning in early spring just after Japangrass germinates, but before overstory trees have leafed out, or burning during August and September before Japangrass has seeded. Burning during mid-summer is difficult because of high litter moisture as a result of overstory forest shading. Japangrass can also be managed using a variety of herbicides, including grass-selective herbicides at relatively low application rates.
