Holes on Rhododendron leaves
I have small bite holes around the outside of my Rhododendron leaves. Having looked at various online forums I seem to have established that it's an animal that enjoys a night picknick!. But how can I really get rid of this animal and save the leaves from being further attacked? I live in Switzerland and find it not always possible to get the same products as in England (or Australia) so would therefore have to resort to a 'natural' form of a fighter. Any suggestions would, as usual, be greatly appreciated.
