- 1). Fill a 2 1/4-inch pot with soilless planting medium and set it aside. Create a medium from a mix of perlite, peat and nutrients. It is used because field soils do not enough provide aeration, drainage and water-holding capacity necessary to stimulate root growth.
- 2). Sterilize your razor blade by spraying it with rubbing alcohol.
- 3). Slice a cutting from the tuber that has at least two laterals and a pair of new cotyledon leaves, which are soft, succulent leaves, and the tip is preparing to open the second set of lateral leaves. Cut about 1/16 inches above the tuber. This measurement is just below the leaf node, which is a small bump under the leaf.
- 4). Clean the cutting by trimming the sprout and cut 1/16 inch below the leaf node, This will clean up your cut, as many times the first cut is a bit messy. Remove any dirt or excess leaf matter from the stem.
- 5). Immediately place the cutting in root stimulator. Follow the manufacturer's directions.
- 6). Make a hole with a pencil in the soilless planting medium about the size of the stem of the cutting. Place the cutting into the soilless planting medium and firmly pat it down.
- 7). Water the pot and keep it moist. Never let the pot go dry.
- 8). Label the pot. Write the date and the name of the variety on the label.
- 9). Place the planted cutting in a humid and warm place. The cutting needs at least 6 hours of light per day. If you do not live in a tropical environment, cut a few holes in a clear plastic bag and place it over the pot to increase the humidity. Within two weeks you will know if your cutting has sprouted roots, as you will either see new leaves or a dead cutting. Transplant the cutting to a bigger pot in three weeks.
