London, United Kingdom
Hello, I wonder if anyone can give me some ideas of whats wrong - I've inherited a fairly large garden with rhododendrons which are at least 70 -90 years old. The were in a huge high 'bunch' but are slowly dying. One died almost overnight and the rest look sickly even with all the rhodie feed. If cut back they seem to grow from the bottom but the tops are really dead. Help??
