In the stump removal topic on this forum, a guy mentions Epson salts will rot stumps. Had some, so filled all the drilled holes with the stuff.
The stump rot from Peavey did nothing.
So, because I have grass from leaving the lawn too long & a lawn sweep, I started a pile on each stump.
See what happens in a couple years with cooking grass on them !
I have no idea why the above guy would bag it & put under a tarp. Best/fast to rot if kept wet.
