GeoPlanter is a breathable fabric planter that air prunes your plants' roots when they reach the end of the container. The air root pruning process forces the roots to branch out with more fibrous feeder roots which are much more efficient in taking up water and nutrients. This very durable geotextile fabric is porous, allowing air into the root zone and provides great drainage creating a healthy environment for the roots. This combination of air root pruning and aeration of the root zone allows your plants to reach their fullest potential. The GeoPlanter is framed with pvc to give you a rigid, framed bed for all of your planting needs. It is UV stabilized for years of use in direct sunlight. All of the seams in the GeoPlanter product line are sewn with a high quality bonded polyester thread that will withstand constant moisture and UV exposure. The GeoPlanter is easy to assemble and is reusable, lasting for 3 years or longer under normal gardening uses.
