Wirestem muhly (Muhlenbergia frondosa) is a warm season perennial grass that is native to North America. This weed not only produces a dense rhizome system but is also a prolific seed producer (3,600 to 125,000 seeds per plant) which enhances it’s reproductive potential. Wirestem muhly populations have been increasing and spreading in Wisconsin over the past few years. Because there is little published information on the growth and seedling survival of wirestem muhly, we have done research to quantify the growth of wirestem muhly alone and with corn and soybeans.
