I have this plant/bush growing in one of my borders. It takes up the whole border which is quite deep. I'm guessing it was planted many years ago to help screen the oil tank, but over the years through both growth and wind damage it has moved forward to dominate the border.
I do actually like it and I'm not wanting it to go, in fact I'm quite looking forward to seeing how it looks through spring and summer. Not sure if it does anything or stays as is now!
My question is, what is it and when/how should it be pruned and cut back?
