I have been researching 'Air Pruning' of containers, installed some for my greenhouse tomatoes, they really are growing well, but the jury is still out as regards my viability.
I found this video https://www.youtube.com/watch?v=VPxj8e2r7H0
which I found interesting.
I also found this from the UK http://www.millhousenurseries.co.uk/rootpruning.php
Can I get some opinions whether this idea would be viable for my fruit tree containers?
I keep a peach and apricot and put them in an unheated garage over winter
