two。 Lighting: Douban green likes semi-overcast or scattered light, except for sufficient light in winter, other seasons need a little shading, very suitable for planting in the office, incandescent lamp lighting is just right. If placed in a shady environment, it is easy to grow, the branches grow, and the ornamental is reduced, which is not advisable.

3. Temperature: Douban green prefers warm environment, the suitable temperature for growth is between 20-30 ℃, the overwintering temperature is better kept above 10 ℃, the growth stops below 10 ℃, and it is easy to freeze below ℃.

4. Humidity >: Douban green likes the humid growth environment, grows luxuriantly in the humid environment, the leaf color is bright, and the foliar spray should be strengthened or sprinkled in the growing environment when the temperature is high or the air is dry, so as to maintain high air humidity. It is extremely beneficial to the growth of the plant. It can also adapt to a short dry environment, but not for a long time, generally should be kept at about 70%.

5.
