Ask-a-Dave's-Gardener: Why my PJM leaves are curling, 2 by akirtania

I am a new gardener living in Massachusetts and started a brand new garden with lots of PJM Rhododendrons about 6 weeks ago. A couple of my PJMs are showing signs of stress and the leaves are curling (see the photos). First, I thought it was due to the lack of water even though I have set up drip irrigation for them. I watered them manually too to revive them but they haven\'t shown any sign of improvement. In fact, some branches of one of the PJMs look dead to me. They are next to my AC units on the West side of my house foundation and receive full sun in the afternoon. Please help with any suggestions you may have. Thanks in advance.
