Q:

Is it safe to burn black walnut wood?

A:

Although black walnut wood produces a toxin called juglone, it can be burned safely. It is not most people's first choice for firewood because it is expensive and is mainly used for furniture.

Many people are skeptical about the safety of burning black walnut wood because the tree itself produces juglone. This toxin can be dangerous when it is exposed to plants, animals and children. The wood shavings of black walnut wood are also toxic, so care should be taken when children or plants are around a fire. Once juglone comes into contact with air, water or bacteria, the toxin dissipates. This makes it safe to burn because the toxin is not carried in the smoke.

    How is wood formed?

    A:

    Wood forms in trees during five distinct and successive biological processes: cell division, cell elongation, cell wall thickening, cell death and heartwood production. The key to wood formation lies in the different vascular systems in plants - harder xylem cells replicate faster than softer phloem cells - which is why trees have more wood than other materials.
