Can this rhody be saved?
Hi everyone, we recently moved into a new house with nice landscaping, but after brutal winter here in Toronto (I believe this is zone 6 Canadian, or zone 5 US). it clearly needs some love. There is a rhody plant that was fine last year (bloomed beautifully), but in spring all the foliage seems practically dead (see photo) - there are no intact leaves or new growth at all. Is it completely dead? I tried to scratch branches to see if there is any green below bark, but can't say I am finding much. The exception is the very top cluster of somewhat better looking leaves - I can find green there on the branches. There seems to be quite a few flower buds, but I am not sure these are alive. That's about it. I don't know how old these plants are, or what cultivars, but I can see plenty of old cuts (including down at the bottom), so these might be reasonably old.
Is there anything that can be done to save the plant? Should I still wait for signs of new growth, or is it not going to happen?
Should I do rejuvenation pruning all the way down to 6"? Would that help?
Thanks a lot!
