The Black Walnut is a delicious flavoured walnut. It has sweet tasting meat with a rich aromatic tone. Can be eaten fresh and is popular in cooking. The nuts are thick shelled and take a bit of extra strength to crack open. Usually depending on the location and climate, the tree can start to produce nuts around 10 years of age. Expect to harvest nuts around mid-late October. It is also highly regarded for its timber for wood makers but with its slow growth and rarity on the prairies, it’s a beautiful tree that is worth keeping on its own. Our seed source is from large healthy trees just right outside of Edmonton, AB. These young seedlings will have inherited the hardy genetics from the parent trees.
Planting location is important, so choose your planting site wisely. Black walnuts have the best success growing in sheltered yard sites or an urban locations(micro climate). In colder climates such as zone 2 you can expect winter injury and difficultly producing nuts. It’s a slow growing tree and also slower to break dormancy in the spring. Black 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 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.
