NEW! Create an advanced root system! A unique advancement in container technology! The Smart Pot prunes roots as they reach the pot sides to spur horizontal root branching. A highly branched, fibrous root structure is the key to growing a better plant — with more flowers and fruits, and more resistance to insects and diseases. The soft-sided, fabric container has the rigidity to hold its shape and can even support large trees. In fact, commercial tree growers have used the Smart Pot for over twenty years to establish healthy root growth before transplanting. Use it as a container, or place it in a decorative pot to make transplanting easier. Sets of 3.
