The best time to divide the plant is in the spring or fall. The plant should be lifted from the ground, and the root system should be gently teased apart into smaller sections. Each section should have a good root system and confirmed leaf growth. The divisions can then be potted up in well-draining potting soil and kept in a warm, bright location.
Any of these three methods of propagation can be used successfully to propagate new plants of Polygala splendens Exell. It is an attractive shrub with beautiful flowers and will make a great addition to any garden.
