Aerial roots can grow relatively quickly, and the aerial roots of the plants will get attached to the moss pole, and they will get nutrients and water from them. Therefore, it is important to water the moss pole, ensuring it remains moist. Moss is a water-loving plant, so the risk of overwatering is a lot less than other indoor plant varieties. Watering aerial roots indoors can sometimes be difficult; consider regular thorough misting of the entire moss pole to make it easier.
