Umtiza listeriana is best propagated by seeds rather than cuttings, which are very difficult to root; even when using tip cuttings, they often do not root. Collect seeds in winter (May, June or July). Either take a mature (brown) seed pod, or collect the seeds off the ground around the mother tree after they have been released from the pods, and use a paper bag to prevent moisture being created, if plastic is used. Prepare a sowing mixture of sifted, fine-milled bark, sand and compost (3:2:1). Prepare a seed tray by sterilizing with a sterilizing agent, to prevent contamination from fungal, bacterial and viral pathogens.

After seeds have been collected they can be stored in cold storage or at room temperature. Treat the seeds with a fungicide to prevent damping-off during germination. Add a layer of coarse bark at the bottom of the seed tray to allow for sufficient drainage and add the sowing mixture to the level of the surface. Insert the seeds slightly below the surface, about 10 mm deep. Place the seed tray in a shady spot with free flowing air and water. Germination should take place within 4 to 5 weeks. When the first 2 sets of true leaves have set, transplant into a 9 cm pot or a 4 litre nursery bag, using a general potting mix of fine bark, sand and compost (fine bark 2: river sand 2: compost 2) and add a slow-release fertilizer to promote growth.

Umtiza listeriana is a slow grower. As the tree grows, more root space will be required to speed up the growth. Umtiza can be planted along the fence or in the middle of the garden bed, in full sun or shade. Plant herbaceous perennials and small shrubs around the tree.
