With over 20 years of experience, Hsu continues to be a leader in Wisconsin’s composting industry and has several certifications on our products.

How We Began Composting

Trowel with DirtIn 1994, Paul Hsu decided to return to growing ginseng in its native setting, the hardwood forests of Wisconsin. Ginseng growers in the 1900s always claimed that ginseng required leaf compost to protect and promote the health of ginseng plants. With that information and years of research, we developed and built our commercial composting operation.

While we still use leaf compost on our woods grown ginseng, we found greater demand for high quality compost products from discerning local consumers and customers. In 2001, we obtained the United States Composting Council (USCC) Seal of Testing Assurance (STA) and received a 100% Biobased certification from the USDA BioPreferred program in 2012. Hsu strives for excellence and continues to add high quality, sustainable growing products to our list of offerings for customers throughout the Midwest
