Brown, crispy edges on big-leaf maple leaves this time of year usually aren't disease. After a dry Oregon summer, it's often a sign the tree is pulling back on water use to conserve itself, especially on the south and west sides of the canopy.
Leaf scorch on its own isn't an emergency. But paired with early leaf drop, dieback in the upper canopy, or a trunk that looks stressed, it can point to a root system that's struggling with more than just seasonal dryness.
The distinction matters because the response is different. A tree recovering from normal summer stress needs deep, infrequent watering. A tree with an underlying problem needs a professional look before fall storms test it.
If your maples are showing more scorch than usual this August, it's worth having a second set of eyes on them before the wet season arrives.

Authentic job photo preferred: a close-up of scorched maple leaf edges alongside a healthy section of canopy, or an arborist assessing a maple crown on-site. Real leaf and canopy photos outperform generic tree imagery.
