Manchurian Walnut

The Manchurian Walnut is native to the Eastern Asiatic Region and widely known for its hardiness, surviving temperatures as low as -45° Celsius. Its beautiful broad leaves and fast growth rate make it a great addition to any cold-hardy nut orchard.

Harvesting these nuts can be challenging due to a hard shell and difficult retrieval of the nutmeat, but that smoky, earthy flavour makes it worth the effort. Trees start to produce from 10-12 years after planting. A perfect choice for those wanting to experiment in cold-climate growing, this rare tree is hard to find.

These are seedlings from productive Canadian Prairie (zone 3) sourced trees.

Growers Note: Manchurian walnut trees flourish in loamy, nutrient-dense soil, and thrive when placed in sheltered locations with minimal exposure to winter winds.

The Manchurian Walnut exudes lesser quantities of allelopathic compounds compared to other walnuts, however please choose your planting site wisely 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.
