Western Sycamore Bark Cracks: Natural Exfoliation

Vertical 4-inch cracks at base of 20-ft western sycamore in LA are normal bark shedding. Sycamores exfoliate bark as they age, starting near base. Don't peel loose bark—it damages new tissue. Green, full canopy means tree is healthy. Cracks are ornamental, not a problem.

Normal Process

Bark peels in plates naturally.
Starts low, progresses up.
Do not assist peeling.
