<div dir="ltr"><div class="gmail_default" style="font-size:small">I have had success outcompeting stilt grass in a stream valley habitat with a combo of bottlebrush grass, chasmanthium, boehmeria (sp), packera, the more assertive native ferns and lizards tail in moister areas. Perhaps it is the shade. The densest stands seem to be in meadows in full sun. </div><div><div class="gmail_signature" dir="ltr" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr">Kathleen Michels, PhD<div><a href="mailto:michelskm2016@gmail.com" target="_blank">michelskm2016@gmail.com</a></div><div>301-922-3816</div></div></div></div></div></div><br></div><br><div class="gmail_quote"><div class="gmail_attr" dir="ltr">On Mon, Aug 31, 2020 at 8:37 AM Marc Imlay <<a href="mailto:ialm@erols.com">ialm@erols.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;padding-left:1ex;border-left-color:rgb(204,204,204);border-left-width:1px;border-left-style:solid"><div lang="EN-US"><div class="gmail-m_-6653798598847982302WordSection1"><p class="MsoNormal"><span style="font-family:"Arial",sans-serif;font-size:14pt">Microstegium versus Perilla<u></u><u></u></span></p><p class="MsoNormal"><span style="font-family:"Arial",sans-serif;font-size:14pt"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-family:"Arial",sans-serif;font-size:14pt">I came across a huge mono-culture of Japanese stiltgrass about 25% of an acre.

Is this just one non-native invasive outcompeting another one? Or is there another possibility that could be explored? For example, reintroduce Mentha arvenis.
