how to kill yucca

How do you kill this stuff? I have dug it up, put rocks on it, you name it. It comes back no matter what.

Doug says start digging, keep digging. Every bit of root you leave will produce a new plant. Every time you see a new shoot, simply dig it out. It will take several times but eventually the roots get worn out, depleted of energy and they die.

tried round up
by: Anonymous

I tried round up all last summer and that didn't work. I dug out the roots and thought I got it all. I even celebrated. Than after the snow melted this year, I saw what looked like 2 large plants. Nope. It was more like 7 plants all grouped together. I'm thinking they are just shoots off of one root.
I've been trying round up and another brush "killer" they are turning the leaves white, but nothing else.
I am going to dig this weekend and drill into the root and pour something directly into it.
I have even tried covering the plants with totes to block out sunlight, and that didn't help either.

I think I've killed a yucca......

Burned them to the ground, sawed off as many leaves as possible, with a large drill bit, drilled into each whorl, used a funnel to pour in lethal undiluted weed killer, covered them with salt and waited.....been 4 weeks and no sign of regrowth.

I can't get it to grow where I live but everyone else can. What am I doing wrong? Mid-Missouri.
Vinegar

You might try vinegar to kill the yucca. It worked on greenbriar when nothoing elsed seemed to do any good. And it's environmentally safe. Beats using Roundup, which didn't work.
drown the yucca
by: Anonymous

One way most people kill a yucca when they don't want is by watering them everyday for a few weeks at the most. May just rot them out all the way down in the roots. This is want I learn when I was working at the garden centers,:-) Really! bets digging ,most likely,anyway,best of luck to you.
