Air pruning-happens naturally when-roots-are exposed to-air-in the absence of high humidity. The-roots-are effectively "burned" off, causing the plant to constantly produce new and healthy branching-roots. If-roots-are not exposed to-air, they continue to grow around the container in a constricted pattern.
