i have a peony rose that has sent up new shoots. The old growth is still attached. Will the new growth die with the frost regardless of cutting the old growth out?
Is that a sort of paeony or a rose?
It's a paeony.
Herbaceous paeonies die back in winter.
The woody ones (tree paeonies) act as deciduous shrubs.
Anything leafy will not survive the frost but if it's a hardy one it will all come back next year
