The harvest from our test garden Curious? How does it work? : The secret is ‘air root pruning’, a completely natural and automatic process. Simplified: Air root pruning causes plants to branch and become feeder roots, maximising the plant's ability to intake water and nutrition, increasing growth and overall plant health. When roots come into contact with air, the plant reacts witha ‘self-cut’ of the affected root tip to protect against dehydration. It then begins at a different, more central location with new lateral root growth to compensate for this ‘loss’. This so-called air cut always happens at the edge of the air-permeableplant bag and repeats itself until the container is filled with roots and root tips. The result: More roots! And more roots mean more opportunities to absorb nutrients. The plant can produce more flowers and fruits. And a positive side effect, the steady air permeability prevents harmful waterlogging
