I read that the sawdust from my dust collector can be used as mulch. There was a warning about black walnut being a herbicide.
Would anyone know how much it would take to cause problems, or is any amount too much?
I want to put it around my pond. I don't care if it kills the weeds and grass under it, just concerned about things around it. I don't use a lot of black walnut, but I do use some.
Thank you
Andy
