Black walnut

Name: Black walnut

Botanical name: Juglans nigra

Light requirements: Black walnut trees require full sun to grow healthily and produce a good crop of nuts. They thrive best in areas with ample sunlight.

Soil and watering needs: This tree prefers deep, fertile, and well-drained soil. It's relatively drought-tolerant once established, but regular watering during dry periods is beneficial, especially in the tree's younger years.

Description: Black walnut is a large, deciduous tree, often growing 50 to 75 feet tall, sometimes taller. It has a broad, rounded canopy with pinnate leaves that turn yellow in the fall. The tree is notable for its dark, ridged bark and large, round nuts enclosed in a thick, green husk. The nuts are known for their rich flavor and are encased in a hard, thick shell.

Medicinal and other uses: The nuts are highly nutritious, rich in protein and healthy fats. Black walnut has been used in traditional medicine, particularly for its anti-parasitic properties. The wood is highly valued for its quality, strength, and dark color, used in furniture, cabinetry, and gunstocks.

Origin and distribution: Native to eastern North America. It's commonly found in forests and rural fields and is also a popular tree in urban parks and large gardens.

Interesting facts: Black walnut trees produce a chemical called juglone, which can inhibit the growth of certain plants around them. They're known for their longevity, with some trees living for hundreds of years. The harvesting and cracking of the nuts can be labor-intensive due to the hard shell.

Ideal conditions and care: Black walnut trees require minimal care once established. They should be planted in an area with enough space to accommodate their large size. It's important to note that due to the juglone, certain plants may not grow well near black walnut trees. Regular pruning is not necessary but can be done to maintain shape and remove any dead or damaged branches. Watch this video for information about pruning your walnut trees!
