Cottonwood trees, like many other trees, produce new trees from root suckers. Even after you cut down an old or unwanted tree, you will have a yard full of new trees from the roots. This is a guide about getting rid of cottonwood roots.
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.
