Rhododendron Plants

Q.My Rhodedendron appears to be dying.

Zone Cheltenham Gloucestershire | Anonymous added on May 20, 2020 | Answered

I mistaking transplanted my Rhodedendron into a larger pot in the autumn using no acid soil. Flower heads set but did not open and later died. I discovered green fly in the spring, which I successfully treated. I replanted with ericaceous soil and now the leaves are crisp and dying. The stems are still green under the outer skin. I have fed with ericaceous feed as directed and also sprayed the leaves with water and also with a dilute mixture of ericaceous liquid feed.
The plant thrived very well for more than six years until I transplanted it.
What can I do and please can you tell me if there is any chance my plant will survive.
Many Thanks for any advice you can offer. This plant is of sentimental value.

Leaf scorch, which is what your problem sounds like, can take place when the weather changes abruptly from overcast to warm sunny or windy. Mulch around the base of the plant without letting it touch the stems, and water it deeply.
