My mother (in Zone 5, MI) has two Japanese Kerria shrubs that die back to the ground each winter. They come up from the ground in the spring, but do not bloom. Do they only bloom on old wood?
I had two at my previous house in Z4 and they were beautiful, which is why she chose the Kerria. Mine were located on the east side of the house, so were protected from most of the winter winds. Hers are more in an open but shady location. Does she need to protect them somehow in the winter?
Any advice will be appreciated.
