RE: Tree Stumps?
I have read several articles about using high nitrogen fertilizer on them. It works for me cause I cant burn where I live.
Just drill some holes and use something like 30-0-0 which is what I have used in the past. It does the same thing as Stump Rot products and its alot cheaper. I bought a 40lbs bag of 30-0-0 at Home Depot for about three bucks.
After you put the fertilizer in the holes add some water. Keep in mind it wont happen over night . The nitrogen is what speeds the decomposition process.
Good Luck
