Juglans nigra (Black Walnut) Seeds

Zone: 4 to 9.

Native to eastern North America.

Black walnut is a handsome and valuable tree, cultivated as a forest tree for its high-quality wood and edible nuts. It is a long-lived tree, sometimes exceeding 200 years in age. It prefers full sun and grows best in soil that is deep, fertile, and moist but well-drained. It has a medium growth rate of 1 to 2 feet per year. The Black Walnut is a member of the Juglans family. Its roots produce a substance named juglone that is toxic to various plants. The production of juglone is a protective response by the tree to assure its survival. Hence do not plant other plants under the canopy of the Black walnut tree.

Size: Height 50 to 75 ft; Width 50 to 75 ft.

Nuts have a short shelf life so it is best to plant immediately or keep refrigerated until ready to plant.

Germination Instructions

Stratification: Black walnut nuts require 90 to 120 days cold, moist stratification at 3° C (37° F) to 5° C (41° F).

  1. Mix some soilless mixture for starting seeds or sand and vermiculite, moisten with water and place it in sandwich bag(s). Note: mixture should be moist not soggy. The bag(s) should not be sealed. Poke holes or leave partially open for air.
  2. Place the nuts inside the mix and refrigerate for about 90 to 120 days. Occasionally check to see if the nuts are starting to sprout.
  3. After the required time plant the nuts in soil 2 inches deep in a sheltered spot in the ground or in deep pots where they can grow.

Protect the pot or site from squirrels or other animals that may discover and eat the nuts.
