Expert tips
The key tip
Generous sunlight, well-drained soil, light organic matter at planting. Once established (2 years), the plant is very self-sufficient.
The common mistake
People think it's a delicate plant: it's robust but hates compacted soil and standing water.
The pro's trick
Don't divide juvenile plants: Strelitzia hates root disturbance.
Care
Light exposure
Place this plant in full sun to guarantee generous and regular flowering. It tolerates bright light for long hours and needs it to fully develop its magnificent flowers. Indoors, position it near a south or west-facing window.
Watering
Water regularly during the growing season (spring-summer) keeping the substrate slightly moist, without excess. Reduce watering in autumn and winter, allowing the soil to dry between waterings. Avoid stagnant water which could rot the roots.
Soil and repotting
Use well-draining substrate, made up of potting soil mixed with sand or gravel. This plant appreciates light and aerated soil. Repot every 2-3 years in spring, without significantly increasing the pot size.
Fertilizer
Apply a balanced or potassium-rich fertilizer from May to September, approximately every 15 days. Reduce or stop feeding in winter during the dormant period. Excess nitrogen fertilizer can promote foliage at the expense of flowering.
Pruning and maintenance
This plant requires virtually no pruning. Simply remove dead or damaged leaves as you notice them. You can thin out the base if the plant becomes too dense, which will improve air circulation.
Diseases and pests
Indoors, watch for spider mites in dry conditions and mealybugs. Excess stagnant humidity promotes the appearance of fungi. Ventilate regularly and inspect leaves, especially the underside, to detect any problems early.
Did you know?
Strelitzia juncea stands out from its famous cousin Strelitzia reginae through its extremely fine and upright leaves, which resemble rushes. This very airy form gives the plant an elegant and graphic appearance, in striking contrast with its flamboyant flowers. In South Africa, its natural habitat, it fascinated 19th-century botanists with this unlikely alliance between discreet foliage and a spectacular inflorescence resembling the head of a bird of paradise.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
