Watering:
Water the plant only when the top inch of the soil is dry. If your plant develops brittle leaves that turn yellow, that means it is not getting enough water.

Fertilizer:
Fertilize the plant at least twice a month while its growth period is active. Use a standard 10-10-10- liquid fertilizer that’s diluted by 50%. These plants require less fertilization during inactive growth and feeding times should be decreased.

Re-potting:
Re-pot with fresh potting soil and some fertilizer when it outgrows for every two years in the spring.

Temperature:
Temperature must be warm around 18 to 24 degree Celsius.
