I need to remove a mature Cardoon. I have dug out a lot of root, but it is fibrous, and DEEP. I would like to replant the area, and not sure which, or if any, rootkillers should be used.

You may need a nonselective herbicide containing glyphosate to kill the remaining roots. Be sure to read and follow all label instructions.
