much the full annual cycle that is also essential. Any tips on this would be appreciated. <o:p></o:p></p>

My answer to your question is to remove the plants before they flower, which is in the fall for both. (I never understand why so many wait until fall to do this, in a panic, given that there’s 6 months for removal prior to flowering and seed set!)

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Question for the group: I work in an area where it is very difficult to bag up invasives and haul them out. At this stage of the year, I run across perilla or microstegium that
is obviously late in it's life cycle. The question is: <u>At what stage do the seeds for these species become viable, so pulling the parent plant out literally would not reduce it's seed production?</u> <o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Even if all the seeds will be viable, there still may be value in pulling-- it seems to me that creating a bundle and sticking it somewhere inhospitable will result in less spread
than if they are out and being dragged around by every critter that passes by. I find myself with the same question about long-bristled smartweed, Artemesia annua or vulgaris, and in the spring, garlic mustard. <u>Does anyone have an approach for deciding
when is it better to just leave these standing and deal with them later? </u><o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="font-size:14.0pt;font-family:"Arial",sans-serif">I came across a huge mono-culture of Japanese stiltgrass about 25% of an acre. In the middle of the patch was a monoculture
patch of Beefsteak mint about 15 feet x 20 feet with almost no stiltgrass. There were two other beefsteak patches about 5 x 10 feet with no Microstegium. Is this just one non-native invasive outcompeting another one? Or is there another possibility that could
be explored? For example, reintroduce Mentha arvenis. Any potential biocontrol?</span><o:p></o:p></p>
