Radermachera sinica likes warmth, and the suitable growing temperature is 20-28°C. Cultivating Radermachera sinica requires relatively moist soil and display environment, with air humidity of 70% to 80% being preferable.
When placed outdoors for care in summer and autumn, watering by spraying the plant and the surrounding micro-environment should be strengthened to create a cool and humid suitable environment for it.
