My dad's Japanese Maple gets these spots on the leaves then the edges dry and curl. It seems like it might be predominantly on one large limb, but I would have to see it later in the summer to be sure. It has been doing this for many years now without any real die-back of the affected limbs, just unsightly foliage as the summer heats up. The tree has been in the ground for I would guess around 8 years or so and otherwise seems fine. Any help would be great. Thanks
