Question: How can I remove an unwanted tree and its stump and roots?

Answer: You have three good ways. Cut it off 15 to 18 inches from the ground and pull it out using a pickup truck and a very heavy tow chain wrapped tightly around the stump. Cut as many lateral roots as you can before you start pulling. Your second option will be to have it ground out by an arborist. They have machines that can quickly remove stumps. Your third option would be to wait it out. It will eventually decay, although a sunken area will develop as the wood decays. This is a slow process that is not sped along appreciably by products that will make that claim.
