Fungus on laurel hedge
This is a type of wood decay fungus that is growing on dead or dying limbs. If you follow those limbs upward you'll likely notice that the foliage is affected too. It is not a contagious plant disease that will spread to healthy parts of the hedge-it just grows on dead tissue.
The only treatment would be to remove the affected limbs. This is optional and may be difficult if the hedge is tight growing. No fungicide treatment is warranted.
Hope this helps!
Wonderful news, Brooke! I'm glad we can avoid the fungicide route! Thanks for your time.
