RE: Re: CULT: mulch/alfalfa and weed preventer

We use XL-2G which is a granular form of surflan.  It also has to be watered
in but can be spread with a whirlybird type spreader instead of sprayed on
if that is easier.  Most of my chemicals come from an Agricultural Chemical
supplier found in the yellow pages.
