It grows well in well-drained soil with a neutral pH. Add coconut coir and Pine bark to make the soil more drainage friendly.
Water regularly, during the growing season (April to September), but water sparingly when dormant (autumn and winter). Allow the top of the soil to slightly dry out before watering again.
It prefers ideal room temperatures of around 60°F – 75°F / 15.5°C – 24°C. During winter no less than 50°F / 10°C. Cold weather and damp weather is not good. It loses its color and turns yellow and mushy.
Fertilize every two weeks during the growing season, from spring through summer with a balanced liquid fertilizer diluted by half. Do not fertilize during the winter.

Take 2-3 inch long stem cuttings and plant it in a 2-3 inch pot of equal parts mixture of peat moss and sand and keep it at normal room temperature in the bright filtered light.
