Q.Blight on Cleveland Pear Trees
They developed fire blight last summer. We would like to try to save them. . . . What is the best way to attack?

It is very difficult to control and the plant will look very sorry, even when controls are being used but...
You can try treating the tree with a copper fungicide, starting as soon as temperatures reach about 55F on average in your area. Apply 1-2 times a week for the whole time it is blooming.
Any areas already infected will need to be pruned out. Prune at least 2-3 inches below the infected area. Clean the pruning tool with a 10% bleach solution in between EACH AND EVERY cut.
Even with this, you may not be successful but it is your best option. Good luck!
