Pre-treatment: Nuts are sown in late October and early November using a spreader into prepared field beds. Seed may be floated in water to help determine viability. Seed that floats is normally poorly filled and has low or no viability. Floaters are discarded, while the seed that sinks is retained for planting.
Establishment: Shellbark hickory is a slow growing species. Seedlings are usually 4 inches tall at the end of the first growing season. Seeds are collected from established natural stands and are kept separated according to site, elevation and source.
