I posted a message here over the summer about the wild growth of bamboo
in my backyard.

Someone suggested cutting off the stalk and then applying Roundup to
the part I cut.

Now last weekend, I tried digging up some roots, and as you all know
the roots run all over the place.

I dug up a root that traveled from the fence (about 5 feet).

If I cut the stalks and apply the round up...will it kill the root that
runs across the yard?

For example, if this is my bamboo (l = stalk .... = roots)
l....l.........l

If I cut off the first l, and apply roundup, will it kill the ..... ?
