How can I propagate an African violet?
African violets are easily propagated by leaf cuttings. Select a firm, healthy leaf and cut it off with a sharp knife. Leave 1 to 1½ inches of the leaf stem (petiole) attached to the leaf blade. Fill a pot with a moistened 50:50 mix of vermiculite and coarse sand. Insert the petiole of each leaf cutting into the rooting medium at a 45 degree angle. Firm the rooting medium around the petiole of each leaf cutting. After all cuttings are inserted, water the rooting medium and allow it to drain for a few minutes. Next, cover the cuttings with a clear plastic bag. Secure the plastic bag to the pot with tape or a rubber band. (The enclosed environment drastically reduces the loss of water from the leaf cuttings and prevents them from wilting and dying before they have a chance to root.) Set the pot in a brightly lit location. Roots usually form in three to four weeks. The leaves of new plants usually appear in six to eight weeks. Several plants usually form at the base of each petiole. Separate the plants by carefully pulling or cutting them apart. Pot up plants individually into containers using a well-drained potting mix.
