Hi --
Seeking opinions on what to do, if anything, about brown spots
and discoloration on Rhododendron leaves. I found info about brown
spots with white in the middle but there is no white spots on these
leaves. Well-establishes plants in Zone 6, NJ

Thanks for any insight.

Did you have a wet spring last year?
It's last years damage. Fungal leaf spot of some sort. Not cured only prevented.
In a wet spring you would be spraying fungicides until the cows came home.
