Abstract
An improved fabric container for controlling the root growth of nursery stock planted in the ground prior to transplant is provided. The improved fabric container is formed of a porous, needle-punched, continuous fiber fabric that maintains root growth in the ground such that roots are readily caught and caused to initially penetrate the container, but the fabric functions to constrict the roots sufficiently to produce nodule formation and root branching within the confines of the container.
