Just put the Round-Up on the cut end of the culm. It will not kill
anything else.


Ok, I assume Round-Up is some kind of liquid weed killer?

So I will cut the stalks and then spray the Round-Up on the part still
left in the ground?

What about all the roots that run across the ground?
What do I do about those?
Since they are below the ground, the spray wont get to it, and I am not
cutting them, I am cutting the stalks that grow upward, not laterally.

Thanks
