The cutting should be placed in a warm environment with bright, indirect light. It will take a few weeks for the cutting to develop roots and new leaves.
Division propagation
Division propagation is suitable for mature Polyochnella congoensis Tiegh. plants that have outgrown their containers. This method involves carefully removing the plant from its pot, gently separating the rootball into two or more sections, and replanting each section in a new pot with fresh potting mix. Each division should be watered thoroughly until it establishes new root growth.
Whichever propagation method a gardener chooses to use, proper care and attention must be given to the plants during the first few weeks of growth to ensure they are successfully established and grow into healthy, mature plants.
