In an earlier post, my mom asked for help identifying a cactus she has in her garden. Ross came to the rescue, pointing out that it is a Cereus peruviana and a category 1 invader! Needless to say, she now wants it out of her garden but if we cut it down with a panga we’re worried we’ll spread it around the garden and make the matter worse.
We also don’t want to use anything too toxic that would damage the environment and could get into the water table. I’ve heard that you could use diesel but I’m not sure of the application and what the implications would be. Any suggestions would be appreciated?
