<div dir="ltr">All<div><br></div><div>Many years ago I did some work on assessing if removal was necessary - it is summarized in the attached. I learned that plants produced seeds even if they had no seed pods when pulled. And, they even produced seeds when I pulled off the inflorescences or roots. </div><div><br></div><div>As I recommended back then I still recommend the use of a sacrifice area. If the target area is so large that you can't pull it all in a given year then just pile the pulled plants in the adjacent infested area. That results in time saved in the bagging and hauling and doesn't actually increase the total number of plant formed in the still infested area. There is no increase because there is a lot of density-dependent mortality that occurs. It is notable that I have seen one site where pulled plants have been left on the ground and no seedlings have formed. That was a few years ago in Maryland. I still wouldn't risk it though!</div><div><br></div><div>Mark</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Apr 15, 2021 at 3:03 PM Mike Van Clef <<a href="mailto:mike.vanclef@gmail.com">mike.vanclef@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Similar idea avoiding trash bags is to remove the seed/flower heads from the pulled plant to assure that immature seeds cannot ripen.

That way, if any seeds do mature, they will be concentrated in one location, which will make subsequent workdays easier. Not ideal, but better than generating loads of trash.</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Apr 15, 2021 at 12:31 PM Marc Imlay <<a href="mailto:ialm@erols.com" target="_blank">ialm@erols.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div lang="EN-US"><div><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,sans-serif">Over a decade ago it was found that garlic mustard is one of the few invasive plants that will regrow if left in a pile. <u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,sans-serif"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,sans-serif">Marc<u></u><u></u></span></p><p class="MsoNormal"><u></u> <u></u></p><div><div style="border-right:none;border-bottom:none;border-left:none;border-top:1pt solid rgb(225,225,225);padding:3pt 0in 0in"><p class="MsoNormal"><b>From:</b> MAIPC <<a href="mailto:maipc-bounces@lists.maipc.org" target="_blank">maipc-bounces@lists.maipc.org</a>> <b>On Behalf Of </b>Kenny, Colleen<br><b>Sent:</b> Thursday, April 15, 2021 11:44 AM<br><b>To:</b> <a href="mailto:MAIPC@lists.maipc.org" target="_blank">MAIPC@lists.maipc.org</a><br><b>Subject:</b> [MAIPC] Garlic mustard disposal<u></u><u></u></p></div></div><p class="MsoNormal"><u></u> <u></u></p><div><p class="MsoNormal"><span style="font-size:12pt;font-family:"Segoe UI",sans-serif;color:black">Hello everyone,<u></u><u></u></span></p></div><div><p class="MsoNormal"><span style="font-size:12pt;font-family:"Segoe UI",sans-serif;color:black">Does anyone have experience pulling garlic mustard and piling it on site?
