Aralia can be propagated via stem cuttings, seeds, air layering, or division, with cuttings being the most common method. Key factors for success include warm temperatures, high humidity, and well-draining soil with high organic content. Cuttings should be taken from healthy, non-flowering stems, and rooting hormone can improve outcomes. The difficulty level is moderate; challenges include maintaining the proper environment and avoiding rot. To propagate via cuttings: 1) Cut a 4-6 inch stem section below a leaf node; 2) Remove lower leaves and dip the cut end into rooting hormone; 3) Place in a pot with prepared soil mix; 4) Water and cover with plastic to retain humidity; 5) Keep in indirect light and monitor moisture, ensuring the soil is moist but not waterlogged; 6) After 4-8 weeks, check for root development. Once roots have formed, transplant to larger pots if required.
