Ever wonder what to do with the shells of walnuts, pecans and pistachios? One idea is to save the shells and scatter them as beneficial mulch in the garden. If there is any residual salt on the shells, they will help deter slugs from attacking your plants. One other idea is to use them for indoor houseplants. Soak them in water first to remove any salt, then line the bottom of a planter with shells and fill with soil. It will help provide drainage for the plant and eventually will decompose into beneficial mulch.
