Have I done enough to kill off my Bougainvillea?
I chopped down my Bougainvillea bush this weekend and sent it off in a skip. Chainsawed the trunk as low as I could go then doused it with concentrated RoundUp. These things are like Triffids so I want to make sure it will die and never grow back. Have I done enough? I will attempt to dig out most of the roots once it is dead.
