Notes Horseradish prefers rich, sandy soil and full sun. However, this perennial tolerates most soils except full shade and constant moisture. Caution: Horseradish spreads quickly and can soon take over your garden. It's best to grow it in containers or in an area in your garden where it can spread. Pennsylvania State University announced in 1995 that minced horseradish holds promise in decontaminating wastewater and clean contaminated soils as well. Pennsylvania State's center for Bioremediation and Detoxification reports that minced horseradish combined with hydrogen peroxide will completely remove chlorinated phenols and other contaminants found in industrial wastes. Experiments involve applying the mixture directly to tainted soils or planting horseradish in contaminated soil and tilling the roots just before applying hydrogen peroxide. |
