Growing Tips
Manchurian walnuts prefer rich, well drained soil, but are adaptable to many soil types as long as they have good drainage and some fertility. They are self fertile but we recommend planting at least two as this will create more nut production. They will do best in full sun. They are also known to not exhibit as much juglone toxicity as Black Walnuts do, so they are more compatible with other species of trees and plants that may be growing on your property. However, over time they can affect the growth of Pines, Apples, and other juglone sensitive species. There are plenty that get along with them just fine though, including Elderberry, Hazelnuts, Currants, and many more.
More about Manchurian Walnut
The Manchurian Walnut is one of the hardiest members of the walnut family, alongside Butternuts. These are beautiful long lived trees, that are a great choice if you'd like to harvest your own nutty protein and support wildlife. These rare and tough trees are known to survive extremely cold temperatures, down to at least -40 C! The tree is native to eastern Russia, China, North Korea, and South Korea. The shells of these nuts can be difficult to crack but with a strong nut cracker like the 'Duke' nutcracker, it is a much easier task. The flavour of the nut is delicious and well worth growing for your own harvests.
We were able to harvest these nuts from a tree in the Ottawa Valley, and are very excited to offer them as they are quite rare and deserve to be planted in more northern landscapes!
