Dorset, United Kingdom
I have a large rhodedendrum plant in a tub which is now very overgrown. I have looked on the Internet and am told to do it in march. I had thought that this was the time of year to do it. Please would someone kindly give me some advice. I do not want to kill it!
It is in fact two plants. One red and one purple. This is an old plant which has been in this garden for some years. Sorry I did not make that clear. What I was asking was when should I cut it back? Now or in the spring?
