Using black walnut chips to keep down weeds
I live next door to a black walnut tree farm. Over the years the previous owner of my land allowed the black walnut branches to be tossed into the weeds and treeline along the long driveway. Now I want to clean that up a bit and I'm considering chipping the stacks of branches and using them as mulch in the same area. Since the branches have already been there for some years, I figure that they won't do any additional harm and maybe this mulch will keep some of the weeds from returning. Am I on the right track? Or should I burn the branches?

As long as you do not plan on planting anything else where you place the black walnut mulch, then this is a great idea for weed control. It won't keep the weeds away 100%, but will reduce them some.
