How to control a clumper: Oldhamii
Posted: Mon Dec 02, 2019 3:52 am
About 10 years ago we planted a clumper Bambusa oldhamii in our backyard as a screen from our suburban neighbors. It has been great but it is now slowly inching its way into territory where it shouldn’t be. This past summer I used a mattock / pick axe to dig out rising shoots many times that came into the neighboring lawn a few feet from where it was planted. Now it is creeping into the neighbor’s yard and damaging a fence which is only about 6 or 7 feet from where it was planted. I am looking for guidance on controlling its spread.
First, I am wondering if I might be watering it too much. Being a Californian, I doubt it but I thought I would ask.
I’ve read about using a rhizome barrier of HDPE. I understand this is necessary for running bamboo but for clumping ???? Any alternatives? If not, how thick should the material be? Any ideas would be appreciated. Thanks, Glenn
