We moved into a new house in the autumn. It has a lovely neat bush around the front garden which seems to have slowly deteriorated since we moved in - looking untidy, patchy bits, holes. It's a bit like a boxus but I'm not sure if it is. What could I do to improve the patchiness and general condition?
I did ask the previous owners whether there was any secret to their bush and whether they fed it anything, but they said they didn't do anything other than give it a trim twice a year.
