Cultivation
Strelitzias require warm, frost-free conditions, moist yet well-drained soil and a sunny spot. In frost-prone climates, grow in large pots or tubs in an intermediate to warm greenhouse or conservatory. Move these outside for the summer if desired. Use soil-based potting compost. Shade plants from strong, direct sun, but ensure good light.
Good ventilation is required. Plants need liberal watering when in full growth, plus liquid feeding every four weeks. Water far less in winter. Propagate in spring by removing and potting up rooted stickers.
