Bird of Paradise (strelitzia reginae) should have no less than 4 hours of direct sunlight a day, preferably all day long. Take protective measures when the sun is strong. In the main flowering period in winter, sufficient sunshine is beneficial to increase the yield of flowers. Lighting regulation emphasizes the management principle of "not shade in winter, not sun in summer". The leaves of the plant look better in shade, but there are fewer flowers.
The temperature management of Bird of Paradise is of great significance for Flower production. In general, Bird of paradise is stunted in growth above 40℃, suffers from freezing damage below 0℃, and grows well in the range of 18℃-30℃. It is best to ensure the temperature at night (13℃-18℃) and the temperature during the day (31℃-35℃). In the appropriate temperature range, flower buds can be formed in the axils of each leaf of Bird of Paradise.

The harvest of cut flowers is generally cut when the first floret is in bud or fully open, and the cut flowers for storage and transportation can be cut before the bud shows color. The pedicels of cut flowers should be more than 70 cm. After being treated with water, it can be stored at 7-8℃ for one month after harvest. If long-distance transportation is needed, cut flowers should be transported at a dry temperature of 7-8℃ in the moisturizing box after soaking in water. Lower than 7℃ is easy to cause low temperature injury. During storage, cut flowers are sensitive to gray mold, so they need to be protected with fungicide before storage and transportation.
