Description

Air-Pruning pots are designed to encourage rapid plant and root growth. The innovative design utilizes the plant's own mechanism to encourage root growth by continually air pruning the roots when they reach the holes in the bubbles. By having a more fibrous root system instead of creating a tap root, the plant will not become root-bound.
Root branching occurs well back within the root ball and several new roots grow to adjoining cusps. The process repeats at an accelerating rate until the growing medium is colonised with fresh new roots. Suddenly, when all of the medium’s pore space is filled with roots, root growth slows. Growth of the head of the tree slows too in equilibrium with its roots system. Plants can be held safely for much longer than other pots. The roots do not spiral and plants look healthy. When the Air Pruning Pot is removed and the tree is planted, the abundance of active roots grow outwards and downwards to colonise the new site. The tree grows like a Rocket.
Better aeration
Higher levels of beneficial bacteria
Better nutrients availability
