A two-story Elm was removed two weeks ago and I have grindings from the stump by my driveway.
I am starting to put in a lasagna bed on the other side of the drive. I presently have straw, compost, manure, and other goodies that will go into the bed. Can I put a thin layer of the Stump grindings in this bed? The stump was sprayed with insecticide prior to being ground up. The tree had a bad case of carpenter ants. I will not be planting food in this bed, only flowers. I can't imagine that it would hurt anything but I want to check. Thank you.
