Geopot is a breathable fabric plant container, that air prunes your roots when they reach the edge of the container. This air root pruning process forces your roots to branch out with more fibrous feeder roots, which are more efficient in taking up water and nutrients. The porous fabric allows air into the root zone and provides great drainage, creating a healthy environment for the roots. With the combination of air root pruning creating a better root structure and the aeration of the root zone, your plants can reach their full potential. This bag comes with a flap so you can easily access and harvest potatoes without uprooting the plant!
