About Hartley
Hartley is an older English walnut cultivar with large, attractive nuts and light, flavorful kernels. It is terminal bearing and generally less precocious than modern lateral-bearing types.
Growing Hartley Walnut
Plant a compatible pollen source because Hartley benefits from cross-pollination. Give mature trees substantial space, and monitor for walnut blight and sunburn in hot sites.
