Curling of white oak leaves
2 White oaks, actually Wye oaks, are showing wilted, curled up leaves, mostly on the new growth. I’m suspecting anthracnose. More curling than black spots. Trees look healthy other than the leaf curling. Trees are probably 30-40 years old and open grown. Located near Blackwater Refuge in a landowners yard. Any thoughts?
Curling leaves is usually a sign of stress of some sort, but if you have photos of the leaves (including interior spots you mention), we'd be happy to take a look.

If the trees are important to you, another option is to contact a certified arborist (tree health expert credentialed by the International Society of Arboriculture (ISA)) to come and do an on-site evaluation. Most larger tree companies have one on staff or you can search for one at www.treesaregood.org
