<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal">Such great questions. Not sure if there is any research out there on this topic.

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have only used mulch from invasive species as weed control in garden pathways. Pretty useful but I wouldn’t use it to mulch where I’d like native plants to grow just to be safe. I would love to see the results of a study on this. We are
in the process of taking down many Ailanthus trees these days in Fairfax County.

<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Arial",sans-serif;color:#16325C;background:white">I had nine 30-40’ ailanthus trees cut down and mulched. I did not realize at the time that it is allelopathic. I am trying to re-grow a native Virginia
garden. Should I age this massive amount of mulch, or get rid of it? How long does its allelopathy last? Weeks? Months? Years?</span><span style="font-size:9.0pt;font-family:"Arial",sans-serif;color:#16325C"><br>
