We have a community garden with adjacent small fruit orchard. Both of our established cherry & apple trees, as well as several of our 1-3 year old plantings (cherry, apricot, apple and pear) are displaying significant leaf damage (mostly tender new growth, but also older leaves), characterized by dark brown, then curling up and drying out. Can't see any obvious invasive pest, or evidence of chomping of leaves, just kind of a "blight" to the leaves. Any idea what's going on, and what we could do to help address the problem? We live in NE Bend near Hollinshead Park and Community Garden. Thanks!
