The Bird of Paradise requires moderate temperatures year-round. They can tolerate temperatures as low as 55 ºF (13 ºC), but prefer to remain in the 70-90 ºF (21-32 ºC) range. Above 70 ºF (21 ºC), care instructions do change slightly.
This plant demands bright, yet indirect, sunlight year-round. Too much sunlight will injure the flowers. Above 70 ºF (21 ºC), this plant should be relocated to a partial shade environment in order to avoid sunburn on the flowers.
During the summer months, the soil should be kept moist through regular watering. Throughout the fall and winter, permit the soil to almost dry out before watering. Never permit water to stand in the saucer underneath the plant.
Strelitzia does well in almost any type of soil. A standard potting soil will suffice for this plant's continued health.
Offer this plant a balanced fertilizer every two weeks throughout the spring and summer. During the fall and winter months fertilization to once every month.
Check the roots of this plant in the late winter. If the roots appear to be cramped in the current container, have someone assist you in moving it to a size larger pot. Be careful not to injure the spathe during the transplant process. Also, re-pot young plants which are growing early spring.
This plant prefers normal air humidity inside the home. During the winter months, you can mist the leaves of the plants to simulate rainfall, which will also improve humidity during the months that artificial heating is used.
The Strelitzia can be propagated from seeds or by division. The seeds are woody, brown and small, with tufts of orange on them. When propagating from seed, it will take the newly formed plant up to three years to begin blooming. When propagated by division, the process interrupts the growth cycle of the parent plant, resulting in a year without blooms.
