When the roots of a plant touch the fabric sleeve, they entangle and do not circle. The root tip loses its' apical dominance and the root begins to side branch. A healthy, fibrous root structure soon develops. A better root system gives you better, quicker growth!
Because roots don’t circle, you gain extra time flexibility. When a plant stays longer in a pot than anticipated, Pot Pruner continues to root prune, creating a healthy root ball that explodes with new growth when the plant is shifted to a larger container or field planted.
