Don’s Expert Answers: Hoping that you maybe able to help> We have an extensive hedge of Photinia Robusta, which is doing well with a lot of vigorous growth. However the hedge is protruding over a footpath and needs to be extensively cut back. To do so we would have to cut 6-9 inches from face of the plant, exposing perhaps branches and no foliage.

Don’s Expert Answers: Dracaena marginata (?) plants. I put them in years ago and have cut them back many times. They are now getting rather large and I would like to get rid of them.

Their roots below ground level are very large and impossible to dig out. Any suggestions?
