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
