I had two well established Korean hollies that were wonderful but they
happened to get the most of the rare sun here. I cut them off. Drove
in a few copper nails. Still every year I get to kill the suckers by
cutting. It has been about ten years and the sucker growth appears to
be slowing. But somehow if I am remiss the hollies will be back I¹d
guess with a vengence.
