Fire Blight

Asked June 6, 2018, 9:57 PM EDT

I am a home gardner with 20 apple trees that are around 3 years old. I believe several may be showing signs of fire blight. I did not spray anything until after blossom drop. Wondering what I should do?

Fire blight is a bacterial disease of apples and pears that destroys blossoms, shoots, and limbs, and sometimes kills whole trees. In general, apple trees are susceptible to a variety of disease and insect problems and require a spray schedule to manage them. The best recommendation is to select disease resistant varieties. See our website for photos and more information.

To manage fire blight, we have recommendations for pruning (called "ugly stub pruning" during dry weather) and the spray schedule on our website from Virginia Tech.
