They respond well to regular feeding with a slow release fertilizer and compost. They are however very tolerant plants and will thrive in most soils and can survive with very little water once established. The plants are also wind resistant and grow well in coastal gardens. Strelitzias are sensitive to cold and would need a sheltered position in areas with frost as the flowers and leaves are often damaged by frost. In very cold climates it is better to grow them in pots that could be moved indoors when freezing temperatures are expected.
Propagation is by seed or division.
The plants are slow growing and large clumps that are split or moved will take about two years to re-establish and flower again. From seed, plants given ideal conditions will flower within 3 years. To get a mature flowering plant from seed takes about three to five years. For best results sow fresh seed in spring. Sow in seedtrays filled with a well-drained soil medium at a depth of 1,5 times the size of the seed.
