Hello,
We have seven old rose bushes in a row about 3 feet apart. They are 6 to
7 feet tall and not very bushy. I want to make them much shorter and
hopefully bushier over time. I don't want to remove and replace these
bushes. I want to cut them down to 2 feet or less and work from there. I
suppose winter time is best for cutting. Does anyone have advice or
suggestions how I should proceed?

TIA. Bill S.
