The leylandii should not grow, I took down about 70 last summer and none
have shown any life. I drilled half a dozen 1" holes about 4" deep in each
and a lot of them have started to rot already.

Hi Folks, I'm a newbie on this site so apologies if this question has
been asked/answered previously. I had 8 leylandii trees, (4 each side)
in my small back garden. I have since cut them all down leaving a
stump of approx 6" for each tree. Will the roots still grow now that
the upper tree is cut? If so how can I kill the roots off (without
having to dig them up)? Thanks
