I think my 20 year Rhododendron is dying HELP
Please help, I have a 20 plus year Rhododendron that in the last two years is very sickly. Leaves were curling up and turning brown and falling off like rain. We had buds and flowers this year but much less that last year which was less that the year before.
Lots of dead wood and i'm afraid to cut them off for fear that some sickness will enter the plant through the open wound. This plant has always been a big producer of flowers and leaves now it's looking like a skeleton.
I used copper powder last year on advice from a friend but didn't see any change. I can e-mail pictures to you
Thank you Barry
