Propagation for codon typically involves seed sowing or cuttings. Key factors include maintaining a temperature range suitable for germination or root development, providing appropriate light exposure, and using well-draining soil. Special considerations might involve stratifying seeds if they require cold periods to break dormancy or using rooting hormones for cuttings. The difficulty level can range from easy to challenging, depending on specific species within the genus and environmental conditions. To propagate, follow these steps: 1) For seeds, sow in a seed-starting mix, lightly cover, and keep moist until germination. 2) For cuttings, take a healthy segment, apply rooting hormone, and place in a mix of peat and perlite. Both methods require patience and consistent care until establishment.
