I have a bank that has bamboo coming out of everywhere. I have been trying for two years to get rid of this s###! I have sprayed all kinds os chemicals from Round-up to Spectracide to Ortho, I was just told about spraying with Round-up concentate mixed with Kerosene, I dont know it seems to strong. If I spray with that it wont hurt anything else, nothing around Bamboo. Please any suggestions would be appreciated.
