That leaf spotting isn't always just a cosmetic problem.
In summer, trees are under stress from heat, and diseases can take advantage. Here are diseases we see in the Sherman Oaks and Calabasas area right now:
Oak Wilt: Causes sudden wilting in oak trees. Kills the tree. No cure.
Powdery Mildew: White coating on leaves. Blocks sunlight.
Anthracnose: Brown spots and twig die-back. Weakens the tree.
Root Rot: Tree gets weak, won't recover from heat stress.
The rule: If a tree is diseased, early intervention is key. We can assess what you're dealing with and recommend the best next step.
