Primary propagation methods for coris include seed sowing and cuttings, with the right combination of light, temperature, and well-draining soil being key to success. Special attention should be given to maintaining high humidity levels for cuttings. Propagation can be moderately challenging, mainly due to the sensitivity of coris to environmental conditions. Steps for propagation by cuttings: 1) Select a healthy, non-flowering stem. 2) Cut a 4-6 inch section just below a leaf node. 3) Remove the lower leaves and dip the cut end in rooting hormone. 4) Plant in a moist, well-draining mix. 5) Enclose in a plastic bag to retain humidity. 6) Place in indirect light and wait for rooting, typically in a few weeks.
