Feed every 2 weeks or once monthly with a balanced fertilizer for foliage plants at half strength. Pull out withered or discolored leaves to maintain tidiness. Be aware that too little water, too low humidity, too much salts and excess fluorides in the water can cause leaf tips to turn brown. Mist leaves occasionally to provide humidity, if necessary. Preferably water them with rain water or aquarium water. It is susceptible to root rot if waterlogged, otherwise least bothered by pests and diseases.
