Primary propagation methods for puya include seed sowing and division. Key factors for success are high light exposure, warm temperatures, and well-draining soil. Special care must be taken during seed germination, which can be slow and inconsistent. Puya is generally considered challenging to propagate, with a moderate to low success rate. To propagate by division, wait until the plant has formed offsets. Gradually acclimate the offsets to the outdoor environment if they were divided indoors. Plant in a mix of well-draining soil and water cautiously, avoiding overwatering. Propagation is best done in the spring or early summer.
