Question: What to Do About Fire Blight on Bradford Pear Trees
The flowers on my Bradford pear trees turned black this year! Is this some sort of disease? How should I treat it?
Answer:
While Bradford pear trees are resistant to fire blight, that doesn’t mean they’re totally immune to it (especially in warmer climates). Blackened flowers are an indication of fire blight. Fire blight bacteria can move down a branch and form a canker; it can eventually kill the branch or even the entire specimen. I would have an arborist look at your Bradford pear tree. Fire blight can be treated if it is caught in time. An arborist will locate, prune off and dispose of the affected branches to stop the spread of the bacteria.
