Are Rhododendrons roots poisonous?
Moved into a new house a year ago which has a wonderful established beech hedge fronting the road. It is in the deeds of the house that we have to keep it maintained and at a certain height, etc. Indeed the road is Beechway and was named after the hedge!
Between the house and the hedge there was a 4ft area of grass with nothing growing. I have planted 5 rhododendrons which look wonderful but now am worried that they may affect the beech hedge which would be a disaster!!! My husband says he thinks he has read that their roots can contain chemicals poisonous to other plants. Any advice gratefully received.
