Q: I have access to a lot of crushed peanut hull granules. This is the inert material that broadcast pesticides are eventually applied to. Would they be good for amending my garden soil?
A: This material seems like a perfectly fine soil addition. The hulls would behave like any organic soil amendment. They will slowly decompose in the soil. I think you would be safe to mix a 2 inch layer eight inches deep into your garden or landscape beds.
