Spray them with Tordon RTU. I do alot of tree cutting when i work for my dad during the summer, and when i cut around fence rows, like taking out saplings and other small trees, i spray the stumps with Tordon RTU, from Dow Agrisciences. The stuff is toxic as the dickens, i just have to dab a little on and the stumps a goner. in the woods, id let them sprout. they'll grow up to be big trees some day.
