Ferns on Oak Dying Despite Rain: Chemical or Weather Injury?

Ferns on a large rural oak (near Weyerhaeuser forest) are crispy despite rain; oak leaves sparse and tiny.

Possible Causes

• Herbicide drift from forest management (common near timberlands).
• Sudden cold snap after tender growth emerged.
• Root zone disturbance or chemical application.

Recommended Action

Contact county Agricultural Extension office for an on-site visit. An arborist can assess herbicide symptoms, root health, and oak-specific issues (e.g., oak decline, borers) that remote diagnosis cannot.
