I'm new to this site, and found it during some anxious searching on the topic of fireblight. We have a mature cotoneaster tree which I suspected earlier this year had fireblight; I cut off as much of the affected branches as i could, though probably not to the advised clearance length because they were difficult to reach. We hope that as a mature tree it might survive. However, before this was suspected we planted, a few yards away, a rowan sapling, about 10' tall, and have just returned from holiday to find its leaves are all brown and curling at the edges, and I suspect that this is also fireblight, in which case I think we'll need to get rid of the whole tree. Would be grateful for any thoughts.
