40 mil HDPE rhizome barrier is designed to contain bamboo and other invasive species. The 40 mil thickness is widely recognized as the baseline thickness acceptable in effective bamboo containment.
Bamboo is a fantastic garden plant due to it’s ability to grow quickly and provide privacy as well as aesthetic beauty. When bamboo is left un-contained it can spread throughout a landscape providing a major maintenance issue as well as damage to hardscapes or other delicate plantings.
Our rhizome barrier is composed of heavy-duty HDPE and provides a smooth surface which acts as a very effective root-stop. The bamboo rhizomes (roots) will not penetrate the barrier but instead grow along the side of the barrier instead.
1. Dig a trench around the area where you are planning to plant the bamboo or where the bamboo is already planted. The trench should be 2” less deep than the depth of the barrier that is to be installed. For example if you are installing a 24” barrier, dig a 22” trench.
2. Place the barrier in the trench. If connecting two segments of barrier be sure to overlap the segments by 4 feet, use HDPE sealant tape vertically and horizontally to connect the seam. The taped overlap will prevent the bamboo rhizomes from breaking through the seam.
3. Plant the bamboo according to nursery planting specifications. Be sure to pay attention to any soil deficiencies, compaction and drainage.
In order to control bamboo effectively, proper maintenance must be performed on a seasonal basis. Bamboo rhizomes spread outward from the center of the plant in either spring, summer or fall depending on your location.
Simply dig a trench around the area where the bamboo is planted, place the barrier in the trench and back-fill. Be sure to install the barrier 2” above the finish grade of the soil. This will allow the gardener to monitor and catch bamboo rhizomes that are attempting to “jump the barrier” Cut any rhizomes attempting to overgrow the barrier and remove. If this process is performed annually, the procedure should be easy due to the fact that the rhizomes are soft and easy to remove.
I'm writing this review based on installation and quality of product. I won't be able to determine if it works to block weeds yet. IT came on a big black roll, and was exactly as described. Install was simple enough only needed a utility knife to cut it.
Tough, durable and effective root barrier.
We are now adding five 40 mil rhizome barriers - after bamboo was planted two years ago. We were told many times by the professionals that the Alphonse Karr bamboo would stay in one place. This is not true! However, it does not travel as much as regular bamboo - the rhizomes do move out from the original cluster about a foot at a time befor reemerging. It would have been unbelievably easy to install five rhizome barriers when first planting each of the five 25 gallon boxes. It has been a number of months since we installed the first two barriers and not one rhizome has gone under or jumped the barrier! Happy days!
As advertised. Easy to work with
Easy to work with, and good quality
Was searching for a long term solution to stop sand traveling through a block retaining wall. Replaced the existing rotted liner with 40 mil barrier.
