Do you want to kill the sideshoot or the entire tree? I suspect creosote
will kill the entire tree. Ringing should kill it but Sycamores seem to be
almost indestructible in my experience.

I moved into a house with 3 small sycamores (OK, 20ft high, but not
established yet) in the garden 5 years ago - they still keep coming back. I
suppose I should have dug up the roots but I've adopted the "if you see it,
cut it down" approach, and it's slowly having the desire affect.

Is there a way to kill a large sideshoot coming from
a sycamore tree at near-ground level without chopping
it down? Is it true that trees can be killed by sawing
a ring through the bark e.g. half cm deep? (I read
somewhere ages ago that trees transport nutrients
upwards just under the bark?) Does creosote help
with this sot of thing?
Thanks
