Went out again none that I can see, opened the plant up a bit and took 4 pics, stems don't look healthy like it's neighbor that has clean brown stems. Also some of the leaves do have the brown spots on the top not the underside. It really took a turn for the worse today and I am thinking maybe better to just yank it.

I don’t have much experience with theses type plants. But You may want to remove the dieing one and replant it in a pot in a different spot away from the other nicer plant. Sometimes what ever it is might spread to the others. Once in the pot try to heal it.

you may want to remove it before the other one gets infected...

i would recommend getting a krill (sp) oil based bug spray and treat the infected one and ground around it to avoid spreading...

I agree with the root rot diagnosis.

What’s the rain like coming off the roof onto that spot? I have a spot across the front where everything but ONE Viburnum are vibrant and healthy. The one that’s not doing as well does get too much water when it rains.

Also, you could have a pocket of clay where the dying Rhodie is planted, which is holding to much moisture for it to thrive.

Any problem with a snow dump off the roof there, or is it getting salt from the walkway in the winter months?

Good call to pull the shrub - just in case. I would.

Rhododendron; Voles eating roots?? Give it a pull to see.
