Hello, I was wondering what is the best method you have used to burn stumps? 1) All stumps are more than 2 years old since loggers cut them down. 2) Majority of stumps are pine with some maple, oak, and mahoney (sp?) So I figured that I am going to dig some dirts around the stump giving about 2-3 feet deep. Drill holes about 6 inches to 1 feet deep on center of stump and pour some mix of old diesel, and used oil into the hole and around it.. then let it burn. What you think? Also, I am not sure about using stump decompsitor and then stump killer made by roundup. Probably will cost me too much money in long run. I have PLENTY of oil to burn and can obtain PLENTY more so all I need to do is get more diesel and mix them with oil.
