Nut trees are magnificent, multipurpose trees that provide shade on the hottest days and brighten the environment with bright color in autumn. Of course, that’s a bonus to their primary purpose – providing bushels of flavorful, nutritious nuts. If you’re gardening in zone 4, one of the coolest northern climates, you’re in luck as there’s no shortage of hardy nut trees that grow in zone 4 gardens. Read on to learn about some of the best zone 4 nut trees, and a few helpful tips for growing them.

Growing Nut Trees in Zone 4

Growing nut trees requires patience, as many are slow to produce nuts. Walnutand chestnut, for example, eventually turn into majestic specimens, but depending on the variety, they may take up to 10 years to bear fruit. On the other hand, some nut trees, including hazelnuts(filberts), may produce nuts within three to five years.

Nut trees aren’t terribly fussy, but all require plenty of sunlight and well-drained soil.

Here are some common cold hardy nut trees for zone 4 climates.

English walnut (Carpathian walnut): Large trees with attractive bark that lightens with maturity.

Northern pecan (Carya illinoensis): A tall shade producer with large, tasty nuts. Although this pecanmay be self-pollinating, it helps to plant another tree nearby.

Black walnut (Juglans nigra): A popular, show-growing tree, black walnut eventually reaches heights of up to 100 feet. Plant another tree nearby to provide pollination. (Keep in mind that black walnut exudes a chemical known as juglone, which may adversely affect other edible plants and trees.)

American chestnut (Castanea dentata): Native to North America, American chestnut is a very large, tall tree with sweet, flavorful nuts. Plant at least two trees in fairly close proximity.
