Anthuriums require regular watering, but the frequency varies based on environmental factors. In general, water your anthurium when the top inch of soil feels dry to the touch. During the growing season, water every 7-10 days. Reduce watering in the winter months to every 10-14 days. If you notice signs of overwatering, such as yellowing leaves or root rot, reduce watering frequency. Similarly, if your plant shows signs of underwatering, such as wilting or dry leaves, increase watering frequency.
