Rooting Leaf Cutting
Use cuttings with two leaves and a bit of mature stem. Allow the cutting to callus over for a few hours before putting them in your soil mix, which should contain vermiculite, perlite, and a small amount of actual soil, callous-end-down. Leave them in a warm, sunny area and water them occasionally. When grown at 80 F, the leaf cuttings could have new rhizomes in as little as 4 weeks, however, at colder temperatures, it could take as long as 9 months
