How can Daphne odora in Phnom Penh be preserved to blossom in the Spring Festival?

The reason of Daphne odora's defoliation in Phnom Penh is nothing more than excessive watering, dry soil, soil hardening, improper fertilization and strong illumination. Its growth temperature is 15 ~ 25℃, and it likes semi-cloudy and semi-humid environment. The soil is required to be loose, fertile and slightly acidic, which can be prepared with pond mud, fine sand and appropriate amount of cooked cake fertilizer. During the flower bud differentiation period from July to August, appropriate amount of phosphorus and potassium fertilizer should be topdressing; Avoid flooding and fertilization, otherwise it will easily lead to root rot. In case of continuous rainy days, it is necessary to avoid continuous rain and water accumulation in the basin to prevent root rot and fallen leaves. After the first frost, move it indoors, place it in a sunny place, keep the temperature above 5℃, and control the water by spraying instead of watering. It is expected to bloom during the Spring Festival.
