Sources of Untreated and
Certified Organic Cover Crop Seeds

Compiled by Debbie Roos, Agricultural Extension Agent

This is a partial list - I will be adding to it as time goes by. Always check first with your local farm supply store because they are usually willing to order any seed they do not have in stock (although you may have to get a larger quantity). “Local” means within roughly 50 miles of Pittsboro, NC. Supplies subject to change. Section II provides full contact information for all suppliers.
