Growing Black walnut, Eastern black walnut

Cultivation: Nuts need cold treatment before planting. Although trees are self fertile, male and female flowering may not overlap. A range of varieties or several trees improve this. Because the tap root is easily damaged it does not transplant easily.

Edible Uses: The kernels are used for flavouring. They are used in pastries, confectionary, ice cream, cakes, pies, and muffins. The seeds yiled and oil used to flavour bread, and other foods. The sweet sap can be made into syrup or sugar.

Production: Trees produce nuts in 5-8 years. Heavy crops are normally produced every 2-3 years. Production can continue to 400 years.
