At Vande Hey's we have switched all of our potting mixes to Hsu's perennial mix because of its consistent blend which is excellent in feeding the plant material, but yet great for drainage eliminating wet feet for them. Our perennials have had a much stronger root system along with a much more brilliant color in them.

From Green Bay to La Crosse, they were able to coordinate with local suppliers to minimize cost and supply the blended materials as required per spec. I would never have expected the assistance they provided to us from anyone.
