HDPE (High Density Poly-Ethelene) RHIZOME BARRIER INSTALLATION
HDPE rhizome barrier will prevent running bamboo species from spreading into unwanted areas and will direct all new growth into making your hedge denser thereby enhancing screening /privacy. Installation steps are illustrated in slide show below.
HDPE barrier 30" x 60mil will contain most running bamboos, but for timber bamboo species use the 80mil thickness. For larger areas you can rent a trencher (see last photo); make sure it will go to 28" deep.
