Is Black Walnut Good for Firewood?

Black walnut wood is considered decent firewood but is not typically the top choice for firewood enthusiasts. Here are some reasons why:

  • Burn Time: Black walnut has a long burn time, which is a positive attribute for those looking to maintain a fire for an extended period.
  • Heat Output: Despite its long burn time, it does not produce intense heat. Black walnut is categorized as medium to low BTU among hardwoods, making it less efficient for heating compared to other species like oak or hickory.
  • Flames and Coals: Burning black walnut generally results in lower flames and a tendency to coal rather than create a vibrant fire. This characteristic makes it less suitable for those seeking visually appealing fires.
  • Ease of Splitting: The wood is usually easy to split and dries fairly quickly, as discussed in this guide on how long it takes wood to dry.
  • Fragrance: When ignited, black walnut offers a pleasant fragrance, which can be a desirable quality for some.
