This is our first time to try a Sudex with Sunn Hemp cover on our small patch. The Sudex grew about 3 ft in the six weeks since sown 7/14, and the Sunn Hemp about 2 ft. Will "mow" it to 1 ft when all are about 3 ft and till under in late Fall. Feeds the worms, suppresses RKN, retains moisture, adds organic matter and a little nitrogen.
