When plants begin to put on new leaves in the spring, prune 4-5 inch stem cuttings with at least three sets of leaf nodes, but no buds or bloom should be present. Remove leaves on 1/3 of the bottom half of the stem with pruners. (Do not tear off or damage the main stem.) If the leaves are especially large, clip them in half with sterile pruners. Then, dip the ends in root hormone (mixed in water at a paste consistency), place 1-2 inches down in damp, well-draining, moist potting soil mix, and tamp down around the stem to secure it. Use a 3-4 inch container with drainage that is deep enough for the roots to grow. Set it in bright, indirect sunlight while they are rooting. Check the moisture and humidity daily and add misting to the soil (not the leaves) while the roots are establishing. After 6-12 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.
