  • Physical Characteristics: - Black walnut trees can grow to a height of 50 to 75 feet, with a trunk diameter of 2 to 3 feet. In optimal conditions, they can reach up to 100 feet tall. - They have a straight trunk and a broad, rounded crown. - The leaves are pinnately compound, typically 12 to 24 inches long, with 15 to 23 finely serrated leaflets.
  • Habitat and Growth Conditions: Black walnut trees thrive in well-drained, fertile soils and are often found in mixed forests. They prefer full sun and are relatively intolerant of shade. Black walnut trees are hardy in USDA zones 4 through 9.
  • Economic and Ecological Importance: - The wood of black walnut trees is highly valued for its strength, durability, and rich color, making it a popular choice for furniture, cabinetry, and veneer. - The nuts, black walnut trees produce are edible and have a rich, distinctive flavor. They are used in baking and cooking. - Black walnut trees produce a chemical called juglone, which can inhibit the growth of certain plants nearby, a phenomenon known as allelopathy.
  • Wildlife and Environmental Impact: - The nuts are a food source for wildlife, including squirrels, birds, and other small mammals. - The trees provide habitat and shelter for numerous species.
  • Challenges and Considerations: The allelopathic properties of black walnut trees can make it challenging to grow certain plants, such as tomatoes, potatoes, and some ornamental plants, in their vicinity. They can also be susceptible to pests and diseases, such as walnut caterpillars and thousand cankers disease.
