I got rid of bamboo by digging it out, then applying RoundUP on any emerging
shoots. The shoots came out from under a brick patio, and from under the
neighbor's concrete slab. Many came out very strong as there was a
substantial root system under the bricks.
A few words about RoundUP. It took care of the bamboo shoots I mentioned
above, and some of the neighbor's bamboo that was not dug up at all. It
took 3-4 sprayings, one week apart to kill some that was about six feet
tall. Don't expect it to take out the Bamboo in a single spraying.
Go for it!
