Keep the soil moist in your pot. Watering should be done routinely with filtered water or distilled water that's ideal for contained plants. Filtered water will not contain chemicals that tap water contains. Check the soil in your pot often. If the soil is dry, your plant needs watering. With regular watering, your soil should provide the moist conditions your plant needs. Remember to avoid too much watering or using a pot without a drainage hole. The soil and pot must be well-draining to prevent root rot.
