Removal of pampas grass plant
I have cut it down to ground and treated with roundup. How do I get rid of the remaining "stump"? How deep are the roots or bulbs in the ground? The grass stump is about 4 very around and appears dead. What is the best way to dig up the stump and roots?

You might have to dig somewhat deep with a large shovel to remove the whole clump, but once you do, this should be a very effective way to remove it. Pampas grass does not spread underground by rhizomes or runners, so as long as you remove the entire root ball of the plant, you will be done with it.
