Propagation of luehea can be achieved through seed sowing, stem cuttings, or layering. Key factors for success include warm temperatures, high humidity, and well-drained soil with good fertility. Special considerations include preparing seeds with scarification or soaking to improve germination rates. The difficulty level is moderate, with challenges such as seed dormancy and root development variability. For propagation, 1) collect seeds after fruit ripening, 2) treat seeds to break dormancy, 3) sow in a seed-starting mix, 4) maintain consistent moisture and warmth, 5) transplant seedlings once sturdy.
