Seattle Bamboo is consulting on a bamboo issue in Kurt Cobain’s neighborhood. A client’s neighbor has bamboo on their property close to the property line.

The neighbor’s bamboo has escaped at least once as evidenced by two barriers in place. One appears to have been placed when the bamboo was planted, the other after the first one failed.

Broken black plastic bamboo root barrier standing among bamboo canes and dry leaf litter — The second barrier, snapped and standing loose among the canes it was meant to hold back.

Now rhizomes have escaped again and at least one has traveled under the neighbor’s hardscaping and is growing between the home and a concrete and brick stairway. We will report on this further in the future.

Plastic bamboo barrier split open at ground level, leaving a gap filled with bamboo debris — Split at the seam. Every gap is an open door underground.

These images are of the types of damage that suggest that plastic barriers to bamboo growth are insufficient and not a strategic containment method. Barriers deflect and re-direct bamboo growth underground and even at their best confine a rhizomatous plant, in this case a giant grass.

Fragments of a shattered plastic bamboo barrier lying among bamboo canes and mulch — What remains of the first barrier — fragments in the grove that outgrew it.
