I have several small Dawn redwood trees in my yard. These trees normally shed their needles in the fall, and are bare in the winter. On both of my trees, they are showing more and more brown needles, and it's not even August yet. I'm my area, we've had more than average rainfall (not flooding like many nearby), but from what I understand, these trees are ok with a lot of moisture. I thought maybe Japanese beetles may have been causing them to brown, but I've been keeping them off the trees with traps.
Anybody have any ideas why they are browning already? I can't see any visible disease on the trees, just the leaves turning brown. See attached pictures.
