I had to cut down a dead cottonwood tree. Since that time I have root tips coming up everywhere in my yard. I chop the tips that are coming up, but in a few weeks they are back growing up again. How do I kill them so they don't come back? Please help. I need to kill them to the root.

Round-Up weed killer will probably work. It may take some persistance over a couple of years to finally convince them to not come up. Round-Up works by being absorbed through the leaves of a weed then going down into the root so be sure to spray when you see leaves.
Round up is a toxic chemical and should never be used anywhere, let alone one's garden. Try white vinegar instead.
