Take the tips from the current season's growth from actively growing plants. Transport wrapped in wet newspaper in a sealed plastic bag, and preferably refrigerated. Trim cuttings to 5–10 cm in length and dip in rooting hormone. Use intermittent mist and bottom heat. However, the strike rate is poor.
