Isolepis perrotetti Steud. is a water-loving plant that is commonly known as the Knysna dwarf bulrush. It is a South African species that often grows in wetlands and along riverbanks. Propagation of the plant can be achieved through several methods including:
Division
Division is an easy method to propagate Isolepis perrotetti Steud. and can be done during spring or early summer. The root system of the plant is quite tough, so it is recommended to use a sharp knife to cut through it. It is advisable to use a clean, sterilised knife to prevent any fungal infections.

When the seedlings are well established, you can transplant them to larger containers or outside if the climate is suitable.
Cuttings
Another method for propagation is through stem cuttings. Take cuttings during the early summer and put them in water until they develop roots. Once roots appear, transplant them into a soil mixture and keep them in a bright, indirect light. Water the plants regularly until they start to grow new leaves.
Propagation of Isolepis perrotetti Steud. is an easy process, and the methods mentioned above can be used to increase the number of plants in a garden or as a way of sharing the plant with other gardeners.
Disease and Pest Management of Isolepis perrotetti Steud.
