Where Do Black Walnut Trees Grow?

Black walnut trees, native to North America, are hardy trees that thrive in a variety of climates. They can be found growing across the United States, from California to Maine and from Minnesota to Florida. They prefer full sun and moist, well-drained soil with a pH of 6.0 to 7.0. Although they can tolerate some shade, they will not grow as vigorously in shaded areas.

Black walnut trees are drought tolerant once established and can survive temperatures as low as -25°F. They grow best in USDA Hardiness Zones 4 through 9, but can also be found in Zone 3 and Zone 10 with some protection during cold spells. In areas with harsh winters, black walnuts may require extra protection or mulching to prevent root damage from frost heaving.

The black walnut tree is an excellent choice for windbreaks or shade trees on large properties or farms. It’s also a popular choice for urban landscapes due to its smaller size and tolerance of air pollution. The tree produces nuts that are highly prized both for their flavor and their use in woodworking projects such as cabinetry, furniture making, and veneers.

Black walnuts are typically fast growers when young but slow down as they reach maturity at 20-30 years old. They will reach heights of between 70-100 feet tall and have a spread of 40-75 feet wide when fully grown. The leaves on black walnuts are dark green and glossy above with paler undersides; they turn yellow in the fall before dropping off the tree at winter’s end.

Black walnut trees produce fruit each year beginning around age 5-7 years old; the nut’s hull ripens between September and November each year while the nut itself ripens between October and December depending on your location in the country. The nuts should be harvested before the hull splits open so you have maximum time to dry them out before cracking them open for their delicious nutmeat inside!

Black walnut trees do not require a lot of water. However, they should be watered regularly during the first two years of growth. During times of drought, they should be watered deeply every two weeks to ensure adequate moisture for the tree. Deep watering also helps to promote deeper root growth and encourages healthier foliage. It is important to note that black walnuts have shallow roots and are prone to drought stress, so regular deep watering is essential.


Black walnuts should not be fertilized until the tree has been in the ground for at least two years. Once established, they should be fertilized twice a year with a balanced fertilizer such as 10-10-10 or 8-8-8. The first application should be made in early spring and the second in late summer. It is important to follow the directions on the fertilizer package carefully and not over-fertilize as this can damage the tree’s roots.


Pruning is essential for black walnuts to maintain their shape and size, as well as encourage healthy growth and fruiting. Pruning should begin when the tree is young and continue throughout its life. Trees should be pruned during the dormant season when there are no leaves on the branches. Pruning always involves removing dead or diseased branches, thinning out branches that are too close together, and removing crossing branches that rub against each other as well as any weak or damaged branches.


Mulching around black walnut trees is beneficial for many reasons including conserving soil moisture, controlling weeds, protecting against temperature extremes, and improving soil structure and fertility. A layer of mulch 2-4 inches thick should be applied around but not directly touching the trunk of the tree in order to prevent pests from getting into it or damaging it with their burrowing activities. Organic mulches such as wood chips or shredded bark work best but make sure to keep them away from direct contact with the trunk of the tree so they do not rot it out or cause disease problems inside it over time.
