In June 2007 I reported that our arbutus unedo was hard hit by 2006/2007 winter. We pruned back all the dead limbs and kept hoping it would come back. This year, I found leaf spot on my kalmia. As a result of learning about leaf spot through this forum, I think my arbutus unedo has leaf spot. I have attached a couple of pictures. If so, any suggestions as to what I do ? ... my unedo is 17+ feet high and these leaves are all over it. My kalmia is still in a pot... so a much easier fix - just take off the leaves that are affected and hope for the best. I've googled leaf spot on the internet and what answers I get seem quite complicated. Any ideas?
