The unique Smart Pot Wall Flower Saddle Planter features two planting pouches that each have 3 gallon capacity. It's perfect for vertical plantings on patios, rails, fences, or gates. Grommets allow for easy attachment almost anywhere. The patented Smart Pot is a soft-sided, fabric container that has the rigidity to hold its shape for years of use. The Smart Pot design was originally developed for and has been used by commercial tree growers for over twenty years. The Smart Pot is an aeration container. It has a unique ability to air-prune and enhance a plant’s root structure. 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. Two 16" x 18″ planters, one on each side.
