Take a whole leaf with stalk and a small bit of the main stem at the base. Insert it upright in a soilless mix, so that the leaf rests on the surface. Water and cover with a plastic bag (don't let plastic touch the leaf). Keep out of direct sun and at temperatures of about 65F (18C). Tiny tubers should start to form in about 3-4 weeks. Let the old leaf rot away and then pot up the tubers. Plant the tubers twice as deep as they measure in diameter. |
