This breathable fabric plant container 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. The 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. All of the seams in the Geopot product line are sewn with a high quality bonded polyester thread that will withstand constant moisture and UV exposure. The Black GeoPot Velcro Transplanter is also available in tan.
