Once you’ve won, install a barrier. Dig a trench about 24 inches deep around the perimeter where bamboo used to be, and sink in a heavy-duty plastic rhizome barrier. It’s like a moat for your garden—minus the alligators.
Or, if you ever get tempted to plant bamboo again, choose a clumping variety and put it in a big pot. Keep it contained like a toddler in a playpen. Your future self will thank you.
