Hsu's Greenhouse and Landscape Supply, located in Wausau, Wisconsin, is a manufacturer of various, high quality composts and soil blends.

Since the early 1990's, we have invested in the manufacturing and testing of our products. Hsu acquired it's first license in 1994 from the Wisconsin Department of Natural Resources. 2002 was the start of our affiliation with the United States Composting Council. Hsu is only one of two processing facilities in the state of Wisconsin to obtain this membership, with a certified compost product.

In 2003, Hsu attained it's fertilizer licence, allowing us to broaden our product line to begin blending and selling products upgraded with fertilizer. In continuing to provide our customers with new products, we began to blend custom potting mixes for greenhouses, nurseries and landscapers throughout the state of Wisconsin.

Currently, Hsu occupies multiple sites in the Wausau area and has begun processing material from around the state. Hsu continues to add high quality products, including LaborSavers pre-filled pots and flats, coloring and bagging wood mulches and more.
