Killing Yucca Plants

Q: I have a few yucca plants in my yard I want to get rid of. I need your expertise on how to kill them.

A: My expertise is that it’s really hard to kill a yucca! I got rid of one by cutting it to the ground and chopping as many roots as I could find then waiting a year and digging up all the little sprouts that came from roots I hadn’t yet found before. That was the end of that one but a second yucca that I cut took two years before little shoots started showing up. It is still growing in my backyard
