This is why you leave 1 -2 inches above ground when you install a bamboo rhizome barrier. Pictured is a rhizome from Phylostachys nigra "Megurochiku" coming up for air and diving right back into the ground. A 30 inch plastic barrier with 1 to 2 inches above ground is an effective way to contain a running bamboo in its intended planting area.Although I do love running bamboo, clumping bamboo is nice because it is non-invasive and does not require containment with rhizome barrier. For me, running bamboo belongs in a pot.

Yowee zowie, Sean!!! Looks like one of those sea dragons where all you can see is about bazillion loops sticking up out of the waves... until suddenly, Zap! The head roars up and snaps your boat in two! Good plan about the containers.
