In 1996, Xtreme Gardening began the commercial production of arbuscular mycorrhizal fungi and other plant supplements. These inoculums are cultured from Superior Isolates that have been selected by universities and research scientists in the United States and Brazil. In addition to several thousands of acres or restoration projects being inoculated with RTIs mycorrhizal products, the worlds largest and record breaking Giant Pumpkins have all been inoculated with our commercial inoculums.
