Stem cutting: To propagate, prune 4-6 inch stem cuttings with no buds or bloom from the parent plant. Remove leaves on 1/3 of the bottom half of the stem with pruners. (Do not tear off.) Dip the ends in root hormone (mixed in water at a paste consistency) and place 1-2 inches down in damp, well-draining, moist potting soil mix and tamp down around the stem to secure it. Use a 2-3 inch container with drainage and is deep enough for the roots to grow. Mist inside a clear plastic bag to create moisture and humidity and place the bag over the top of the plantings loosely. There is no need to tie off the bag but allow a little airflow under and into the planting pot. Set it in bright, indirect sunlight while they are rooting. Check the moisture and humidity each day and add misting to the soil (not the leaves) while the roots establish. After 4-6 weeks, roots will begin to form. You can tug onto the stem to ensure the roots establish after new growth begins. Transplant to the garden after the roots are mature.
