Subject: Re: girdling roots in relation to species
I've never seen a fallen tree of any size where a girdling root was
the main
suspect, or even obviously present. Maybe there are research findings
somewhere but in their absence Adam, what were the failures you have
inspected like?
Sorry Edmund, my meaning was not clear:
by failures, I meant planting failures - trees that had failed to
establish.
Again, I don't think the girdling caused them to die (though the
inappropriate depth within the ball/pot wood not have helped).
It's more that the failure of a tree gave me the opportunity to take
it apart.
One does not normally take apart a container root system for the sake
of it....
...but when you do, you'd be surprised at how often you find kinked
and girdling roots in the heart of the root system.
Regards
Adam
