| Aerial roots gather water via humidty and during waterings. I don't know if they store water per say but psuedobulbs do. I think it just depends on the type of plant as far as having areial roots or not when potted in a mix. Many orchids are mounted in nature on trees and rocks and they tend to have a large number of aerial roots. Some orchids only grow in the ground in compost or debris and tend to have all roots under "ground". I would definitely not cut the aerial roots off! It is a sign that the plant is doing well and the more roots the better it can get what it needs to thrive. I think it could cause the plant to be set back if it a main root that others branch off of. |
