Stem cutting: To propagate, prune 4-5 inch softwood stem cuttings (in late spring) 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. 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.
