About Shagbark Hickory

Carya ovata · also called shagbark hickory, upland hickory · edible

Shagbark hickory is a stately native North American nut tree, instantly known by its grey bark peeling in long shaggy plates. It yields sweet, edible nuts highly valued by people and wildlife, plus prized hardwood. Slow-growing and very long-lived, it has a deep taproot, demands patience, and resents root disturbance and transplanting.

Preferred mix: Deep, well-drained loam

Watch for — Transplant difficulty: The deep taproot makes shagbark notoriously hard to transplant; start from small container or seedling stock and avoid disturbing established roots.

If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
