Air Pruning

One advantage of soil blocks is that the roots grow to the edge & stop, instead of wrapping around & getting root bound.

What is Air Pruning?

Air Pruning is a process that only happens with fabric pots and containers, or soil blocks. When the roots of the plant come in contact with the fabric inner wall of the pot they are forced to penetrtate and grow into the breathable fabric. This causes the root tips to dehydrate and branch behind this point. When reached these root tips meet the air on the outside of the pot, causing them to be naturally pruned. This pruning process, called Air Pruning forces lateral branching of desired fibrous feeder roots. These fibrous roots are more productive in the uptake of water and nutrients, resulitng in a more vigorous and healthy plant that utilizes the entire root zone for optimum planth growth.
