Once you stand your bamboo rhizome barrier into the trench, two inches of it are left above ground level. When fully enclosing your bamboo with barrier on all sides, any seam where it meets can be secured with our stainless steel bamboo rhizome barrier seam clamp. Be sure to have a tight seal at the seam with an overlap of only two to three inches and remove any rocks, roots or hard objects if they are touching your barrier.
With many installations you do not need to control the bamboo grove with a barrier on all sides. Leaving an open sided barrier on your property side of the grove encourages the rhizomes to spread in the direction of the open side, allowing for easier maintenance and a simple install without the need for any hardware.
The strength and thickness of the bamboo rhizome barrier, and a tight seam where the barrier meets are the most important factors. We strongly recommend a minimum HDPE bamboo rhizome barrier thickness of 80 mil (2.032mm/.080 inch).
Beware of 40 mil (1.016mm/.040 inch) root barrier. It is not strong enough, and most bamboos will eventually grow right through it. Steel barriers conduct cold freezing temperatures into the root zone of tdhe plant. Wood barriers rot over time, and vapor barrier will not stop the spread of bamboo either.
