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.
