Bamboo escaping from plastic barrier
We've got Phyllostachys Heteroclada and Nigra in our backyard,
surrounded by plastic barriers that are 30" deep. The ends of the barriers overlap a few inches and are joined together by a metal strip and bolts. This was installed by a contractor. I'm finding that the seal isn't very effective - small roots have worked their way through the overlapping area where the strip is, and this opened up enough space to lets some rhizomes escape. The strip has bolts every 3-4" but apparently this isn't close enough. I can't see any easy fix to this, other than just digging inside the barrer near the seams and removing the rhizomes and roots. What I thought might be useful would be some sort of long, narrow saw that I could run along the inside of the barrier to cut the rhizomes. Are there any tools or methods that might help make this easier? I think one mistake the contractor made was not making sure the barrier angled outward. Not much I can do about it now...at least, not easily. The barriers are about 1 1/2 feet from a fence line, so it's tough to work on. |

I suppose you are long past any warranty that might have been in place. It looks like you have no choice but to fix the seam or replace the barrier. I believe 40 mil thick barrier is the optimal thickness. Some suggest the barrier be a minimum of 36 inches wide/deep. -- Travis in Shoreline Washington |
