Rhododendron Pjm Problems - Knowledgebase Question

Cooperstown, NY
Question by doeclif

I have some 36 PJMs (mostly Lavender Pink) in my garden most of which are doing quite well. However, I have about 10 plants which do not seem to be performing well. Group A: the leaves on 3 plants suddenly have curled up tighltly so that they are now tubelike (no indication of root rot revealed by digging up). Have not responded to watering. Are they dead? Group B: the leaves 4 plants are a pale yellow green, almost translucent, not the usual dark green, with the lower leaves quite yellow. Group C: the top leaves on 3 plants are green but the lower leaves are reddish. In our region (Cooperstown NY) we have had severe drought for about four weeks. However, our gardens have extensive sprinklers and during the drought I have supplemented them with additional hose watering each day. Finally, this past weekend we had over 2 inches of soaking rain.
The leaf color on all the other PJM plants is a standard green, not the dark almost mahogany color they were in the Spring when they bloomed. I assume this is normal.

Any ideas on causes and cure? Thank you.
