I have moved into a house in March. There were tags in the garden saying Hydrangea, but no plant stems were visible. Now there are leaves sprouting. In reading about the pruning of Hydrangeas, there is no mention of varieties that die back completely in winter. Is this common? Does it affect blooming? I am not sure what variety I have, because the tags blew away in a storm. I think it may have said Endless Summer. These are on the South/West side of the house, close to the foundation and with large shade trees in the yard. I would like to move them another place in the yard. Can this be done without killing them? If so, when is the best time to move them without disturbing bloom time. I am an experienced gardener, but have never grown Hydrangeas. Any advice is appreciated. Thank you.
In areas where temperatures annually stay below freezing for long stretches, hydrangeas die back every winter leaving a mound of dead stems to prune away in spring.
