OSTRYA DISEASE PROBLEMS
Canker diseases cause dieback of individual branches or
entire trees. Prune out diseased branches, fertilize
regularly, and water during dry weather.
Leaf blister caused by Taphrina virginica causes blistered
or deformed leaves.
Leaf spots are generally not serious. Rake up and destroy
infected leaves at the end of the growing season.
Powdery mildew makes a white coating on the leaves.
