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. I thought I posted this before, but it appears my email address didn't connect, so I am posting again. Thank you.
Depending on the variety, some bloom on old stems, some on new growth. I would leave them until you see substantial growth. Then in the fall move if needed to a shady area. Someone may have cut back not knowing if the shrub bloomed on old wood. Hopefully you will see something, if not by mid summer then it was mistakenly pruned.
