Air Pruning – When the pot prunes the roots15. August 2023
One year of air pruning – a first result
This field maple was in a Tie Pot for over a year.
Time to examine the roots!
In a normal pot I would expect a Acer campinus to grow circling roots of up to one meter length.
Here in this case the air pruning worked without exeption: every single root grew to a hole – as hoped. So due to the contact with the dry air outside the pot, the root stopped growing in length.
- I loosened up the root ball and was perfectly happy with the result: a dense, fine branched root ball. Not even one root had grown excessively long.
- So I trimmed the roots a little and put the tree back in the pot with a little fresh substrate. The amount of lost roots was minimal – in this case this is perfect because the tree is supposed to continue growing quickly. I did not want it to loose speed due to the disturbance oft he roots.
I surely could have planted the tree in a much smaller pot at this point without weakening the tree.
