Fire Blight on new Kieffer pear
I planted 2 pear trees this spring, a semi-dwarf Ayers and a semi-dwarf Kieffer. In the last few weeks the Kieffer has gotten fire blight repeatedly and I've cut it out to where the tree is now half it original height. The Ayers is doing great with no signs of fire blight.
My question is...could the fire blight in the Kieffer be stress related (it was almost twice the size of the Ayers), or might it be symptomatic of a tree that will be causing problems long into the future?
Should I just cut my losses and plant another or stick it out?
Thanks for all replies.
