[MAIPC] FW: The Garlic Monster - Third Year Adults and Beyond.

Tue Jun 2 14:36:55 PDT 2015

I agree with you guys:  I have pulled thousands of garlic mustard
plants--including a few today--attached to massive stumps that have to be
older than two years.  Interestingly, though, there are a number of
articles out there that suggest that leaving the root in the ground will
rarely result in resprouts, and almost never in seed production.  Chapman
et al (2012) in the Natural Areas Journal (v.32 no.3) is a recent example.
If anyone out there knows of a study that shows cut GM behaving like the
short-lived perennial we all know it is, I'd love to know about it.

Thanks.
