Primary propagation of luma can be achieved through seeds or semi-hardwood cuttings. Key factors for success include well-draining soil, moderate temperature, and balanced light conditions. Special considerations consist of treating cuttings with rooting hormone and providing a humid environment for rooting. Generally, propagating luma is moderately difficult due to the need for precise environmental conditions. Step-by-step, sow seeds in spring after stratification, or take cuttings in late summer, treat with hormone, and plant in a mix of peat and perlite, keeping moist until established.
