A native to the Eastern Asiatic Region, this is rightfully our hardiest walnut. This tree has thick shelled tasty large nuts. A good option to experiment in cold climate growing with reported hardiness to -45 Celsius. Our seed source has been selected from Saskatchewan. At the time of harvesting these nuts can be extra work due their hard shell and difficult retrieval of its nutmeat. None the less, an excellent addition to a hardy nut orchard. Rare tree, hard to find.
You’ll need a protected site from the wind for best success and planting in deep rich soil is recommended. Manchurian Walnut trees produce a substance named juglone, which occurs naturally in all parts of the tree, especially in the leaves, nut hulls, and roots. Choose your planting site carefully as it can inhibit the growth of blueberry, apple tree, crabapple, cotoneaster, azalea, rhododendron, lilac, white birch, larch, mugo pine, red pine, white pine, Norway spruce, silver maple, potato, tomato, pepper and eggplant.
