Strelitiza reginae can be propagated from seed and divisions. Hand pollination can be carried out as described by Notten (2002). Seed propagation is discussed in an article by Winter & Xaba (2011).

Once seed has germinated, it is important to pot seedlings in a well-drained fertile medium and to see that they are eventually adapted to a position in full sun. We have had great success with the following potting medium for strelitzias: 2 parts loam, 2 parts sand, 3 parts 12 cm bark, 3 parts compost and 1/2 part bone meal, and 1 part Bounce back® or 1 part 3.1.5 fertiliser.  We feed our plants alternatively in May and November with a mixture of (a) 1 part superphosphates, 1 part 3.1.5, 2 parts Bounce back® and 2 parts bone meal or (b) compost. Compost or the mixture is generously scattered around the root area and watered in over a period of time. At Kirstenbosch potting/reporting, transplanting and dividing plants happens in autumn. This allows the plant to focus its energy on recovering rather than flowering. Mature plants will normally flower due to stress when divided or transplanted, an in-built survival mechanism. Flower stalks can be cut to allow quicker recovery. When dividing mature plants it is important to have a minimum 60-cm clump diameter, so that recovery is faster, more or less two to three years maximum, to full bloom again.
