Nathan and Amanda and I installed bamboo "containment" today above the GCA Circle in the Asian Collections

To prevent "running bamboos" from taking over the garden and then the world, you can install a heavy plastic barrier. First we dug a trench 2" shorter than the liner (~32"). Then we inserted the liner leaving 2" exposed above ground to prevent surface runners from escaping. Next we backfilled the trench leaving an opening to bolt on the binding strap that connects the two ends. Tomorrow we will finish back-filling and plant.
