Preen and Mazus or Sweet Woodruff
 

Hi. I just purchased both Preen for gardens and beds, and the one for
groundcovers.

I wondered if anyone had any experience using this in a bed with
either Mazus reptans or Sweet Woodruff. I see neither of them listed
on the packages, but this is the bed that is the weediest, so I'd like
to be able to use it. I could test it on a small area, but am not
sure how long It would be before I'd know if it was going to harm the
plants.

They never seem to have some of the more unusual plants that I have
listed, which is why I've avoided it in the past, but I just can't get
the weeds under control. Thanks.
