Re: Preen

I don't think you would be able to start from seed the first season if you
use preen,
but the first year (the "Weed Year") of a garden is one situation when my
die-hard mentors do approve of Preen.
If you have an existing stand of weeds, the Preen will not affect them.  It
is a pre-emergent treatment that only prevents new seedlings from
successfully germinating.  Use Roundup on the existing growth.
