Root wrapping in containers is a serious problem as circling root systems are far from productive. RootMaker® containers do not allow the roots to wrap; instead, they direct the roots to air holes where they can't escape and the roots are pruned. Air pruning of roots is accomplished with the use of containers that direct the root towards air where the root tip is dehydrated. When this happens, the root branches. Next, those roots that have branched and reach the side of the container are directed to an opening and are pruned. This process is repeated again and again with the branching roots creating a fibrous root system which has more root tips. RootMaker® Containers also have a root directing bottom, which avoids root circling.
