Welcome to Garden.org,
@SEB ! I agree that it would most definitely help to know where you are located.
I have 2 PJM rhodies -- which both suffered a bit from the two severe winters that we had (2013/2014 and 2014/2015), and one of them totally succumbed this spring. Besides those bad winters the one that died was near a south-facing wall of the house, and under an overhang where I don't think it got enough water (which I didn't realize until too late); and also, I hadn't been giving them an acid-lover fertilizer or doing anything else special for them. I only woke up to the problems with the soil pH when I had problems growing some blueberry plants, I'm afraid. So, if you aren't doing this already, my recommendations would be to work some soil sulfur into the ground around your PJMs and fertilize them with something like Miracid. I'm actually considering digging out my surviving plant and amending the soil with a lot of peat moss and compost -- because the dead one that we took out didn't appear to have sent it's roots out much beyond the root ball from its pot.
