Oak Early Leaf Drop: Drought Response, Not Death

Summer Leaf Shedding in Oak = Survival Strategy

A homeowner's large oak drops leaves like autumn in summer. Neighbors' oaks look fine. Is it dying?

Oaks shed leaves to reduce water loss when soil moisture crashes. It's a controlled shutdown, not death. The tree conserves resources for survival.

Scratch test on accessible branch: green cambium = alive. The tree will reflush when rain returns or irrigation resumes.

Micro-drainage, root depth, species variation, or irrigation differences. Your tree may be on a drier knoll or have shallower bedrock.
