Hawthorne Leaf Blight



Hawthorne leaf blight, also called leaf spot, is caused by a fungus and exacerbated by cool, wet weather. Infection manifests as small reddish-brown spots; then the area between spots will yellow and leaves will eventually fall off. If canopy loss occurs several years in a row it can severely weaken the tree.

Susceptible species

English hawthorne and Paul’s scarlet hawthorne


Prompt removal of leaves with symptoms, raking and destroying fall foliage, and foliar fungicide treatment in the spring.
