Red Robin shrub
I have a Red Robin shrub in my garden and I am constantly having to clean up the lawn because of fallen leaves. It doesn't seem to be deciduous as it generally retains its leaves through the winter. However single leaves fall constantly on the garden and I am usually tidying up every week sometimes more. A lot of the leaves that fall have some kind of black spot on them. Are they falling because its the natural thing to do at this time of year or because they have some kind of disease and if so how can I put it right? I would be grateful for any help with this problem as I don't know whether to cut it down or give it a bit longer.
