With the Black Walnut Harvest underway since October 2, hullers and harvesters across the Midwest are busy collecting and hulling this natural treasure throughout the month of October. The Black Walnuts are collected by hand and sold to a nearby Hammons hulling station where they are prepared for processing. Black Walnut demand is higher than ever, so the opening price of $15 per 100 pounds (after hulling) is an all-time high for individuals and groups who transport their Black Walnuts to one of the 235+ hulling sites across 13 different states.
