Hi everyone, I live in Ireland, as some of you will know, Ireland has a moist climate, as a result blackspot is a problem, I am seeking organic or chemical means to help with this problem, I cut the old growth in December, burn the old leaves, still the blackspot persists..any help much appreciated....Gerry
