Re: Invasive groundcover
You are wise to watch out for the pennyroyal. I had a 3" pot's worth and it
grew to 36" in diameter in one season. I decided to let it grow out of the
herb bed and into the pathway to make a ground cover. I got it all out of
the herb bed and it's coming back in the path just fine. Choking out other
weeds too.
