Will Hi-Yield Root Killer kill bamboo roots? Our bamboo is spreading out of control.

Our bamboo is coming up all over our yard. Is it safe to put the root killer on the grass? Or only on the garden area around the bamboo? Will it kill existing bamboo roots or only new ones?


Hi-Yield Root Killer is labeled for use in sewer pipes and septic tank drain fields to kill roots that are intruding in those areas.  It is not for lawn use.  It can be very difficult to control bamboo that is not being contained from another area where it has been planted. To kill existing bamboo, you can cut the target plants down and spray directly with a high concentration dilution of RoundUp QuickPro
You may consider putting in a physical barrier to prevent further spreading. This needs to be pretty solid and deep enough to prevent the underground roots from spreading.
