Hi, 

Such great questions. Not sure if there is any research out there on this topic. 



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. 



Warm wishes,

See question below. Does anyone have any information or knowledge on this subject? Thanks. 





Ailanthus mulch 

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? 
Thank you so much for your kind consideration.
