Abstract: A plant container system that has sufficient stability to remain upright under strong winds. The system comprises a rigid spacer that defines a perimeter, a plurality of plant containers disposed about the perimeter of the rigid spacer, and a plurality of fasteners for firmly securing the rigid spacer to the rim region of each container, wherein each container has a rim region and is stabilized by the other containers; Accordingly, the spacer secures, couples or links a plurality of containers together in a configuration that stabilized all of the containers. The system is well adapted for use in pot-in-pot production of plants.
