• Humidity: Tolerates average household humidity levels and does not require extra humidity.
• Fertilizer: Fertilize infrequently, once or twice during the growing season with a diluted balanced liquid fertilizer. It needs very little feeding.
• Propagation: Propagate by division when repotting, ensuring each section has a few leaves and healthy roots.
