So, way back when, Jason was complaining about some innocent little stand of bamboo. At the time, I told him this:
The solution is brutally simple. Bamboo only actually grows for a few weeks a year. Jason, all you have to do is cut it down (machete, chainsaw, whatever works). I've seen thinstem bamboo decapitated with hedge trimmers. One gets a kind of grim satisfaction from this work...
Take *that*, you evil plant!
Cut it pretty low to the ground. You want to get the mower over it...
Then wait, and watch. At some point, depending on variety and climate, it will decide "Ah! Look at the time. Let's send up some shoots!"
This is the time for vigilance. Walk around the yard. Whereever you see one of those shoots coming up, step on it. They're very soft at that stage. Do this with extreme prejudice. You want to get them all.
Some varieties will keep trying to send up shoots until they've completely exhausted their energies. Others will tell themselves, "ah, it's a bad year, I'll try again next spring". Other will do something in between. In any case, break off the shoots with your foot. As long as you're vigilant, no bamboo can survive this treatment.
Trust me on this one: no amount of expensive round up, or sweaty digging, will get rid of it. But this method works everytime...
