Q.planting in early november
I am considering planting Winterberry and Redtwig Dogwood in early November. Is that too late? I live in South Central PA. I think that is hardiness zone 6.
Generally in zones 6 and warmer fall planting is fine though November is getting later in the planting window.
Much depends on the weather patterns. If the weather stays warm and the bare roots have time to become established, they can do fine.
With a bare root the feeder roots have been killed and the specimen is basically a stick, a cutting that basically sticks in the ground unable to draw up moisture until it begins to grow.
I would recommend waiting until spring if I have a vote!
