Is walnut wood toxic?
The juglone toxin occurs in the leaves, bark and wood of walnut, but these contain lower concentrations than in the roots. … Walnut leaves can be composted because the toxin breaks down when exposed to air, water and bacteria. The toxic effect can be degraded in two to four weeks.
