Killing a tree is hard work, particularly if you avoid using chemical assistance. You have to cut off a tree's water, food and/or sunlight at a critical time in it's life cycle to do the job.
Trees can be killed without herbicides or chemicals but extra time, patience, and understanding of tree anatomy is necessary. You especially need to know about the function of a tree's cambium, xylem and phloem and how they combine forces to effect a tree's life.
