Saturate with salt and salt water.

[Just mythoughts]

lol let me know when you find the cure!!!

[MikefromOhio]

are there any plants that can act as a predator to this yucca plant?

something that would take over and not allow it to grow perhaps?

the idiots that owned my house before I bought it from there put frikin Kudzu in the back yard. They were semi-diligent about burning it back, but they didn't have a privacy fence, which I do now.

I have to take the weed whacker to it every couple weeks. I rototill ed it yesterday and I hope the grass seed will take hold and kill it....I hope I hope....

Aren't Yucca plants protected? Sounds crazy hugh, but on U.S. forest land, you better not try to cut one down.

Best way I've found to kill plant life is water it, cut the weeds, trim it and try to get it to look real nice on the property.

Have you tried placing a picture of Jane Fonda by it?

Concrete?

From the looks of http://forums2.gardenweb.com/forums/load/peren/msg0718130510862.html you're stuck with it...

[Iowa Granny]

I have no remedy. However, let me warn you that you should remove the flower stalk as soon as it's done blooming or the seeds will drift and reseed.

I've used every method you mentioned (except peeing, hadn't thougth of that) and I still have mine. The tap root is probably 5 ft long, which explains why we can't get them dug out.

Overplant the Yucca with ivy. In a few years the Yucca will be gone....and your fun with ivy begins.

[bigfootbob]

Try a different herbicide. Crossbow or Finale may work. I would cut the plant back and paint the concentrate on the cuts.

It might take several attempts, but you'll get it.

If all else fails call in a licensed commercial spray contractor. They have access to restricted herbicides that will kill just about anything.

1. Borrow a cow.

2. cover it with a clear plastic bag that will trap the heat of the sun.

What did we ever do to you, you anti-Yuccaist !

[Sweet_Sunflower29]

Hmm...

You can't get control unless you dig out at least 48 to 72 inches down, making sure you don't leave any tubes in the ground. You can't just grind this type of tree stump up. As to control if you have shoots, spot treat (break off the stand, tends to have like a cup shape pour directly on the spot.)with 2-4-D, turflon of esther or any good broad leaf chem with a non selective such as round up pro. Make sure no water in area for at least 3 dys. This is what has worked for me.

OK Michigan so your in a deciduous region ...Good.
It takes time but this will work..... Yucca is like a tumor.When you dig at it and disturb it you cause each broken root section to re emerge.
So....... Heres what I did and do for all invasive hard to kill nuisance plants. In the fall when leaves are turning (this is when plants are sending nutrients to the root for winter)cut this piece of crap and any other undesirables about an inch above ground..........then take a small paint brush and paint the exposed stalk with Roundup (tm)or its equivalent.Your plant is sending goodies to the root at that time of year and will deliver this dose of death real quick. This system has worked for me on wild grapes roses bittersweet,Autumn olive,poison Ivy,sumac and oak and the list goes on.I pissed away money all season for years leaf spraying products at the recomended dose only to watch the bottle go dry and the plant flourish....
Key Is... Wait for Fall cut it back and paint it on...you will find out your product last 10x's longer and plants don't come back in spring.
The wild grapes for example when cut in spring and summer will expell a cup of fluid so paintning or sparying is useless where as in fall the cut stalk will suck up the same amout of fluid and if that fluid is deadly...buh bye.
Now Yucca, if disturbed as previously mentioned may need a few extra paintings in spiring and throughout the season depending on how large the beast is/was and you will notice little sprouts popping up all over .Those are thwe disturbed root sections taking hold again....

We moved into our house 5 years ago, and the previous owners planted some yucca plants. I want to be rid of these...FOREVER.

Have you tried showering them with love, encouraging their growth, and catering to their every need. Every plant my mother has treated this way dies in record time.

The stronges herbecide available without special liscense is 'Remedy'. Available in feed stores and ag business that sell fertilizer. For the toughest plants it must be mixed at 25% with diesel fuel. That's one quart of Remedy to 3 quarts deisel. Stuff cost $100 per gallon.

Problem is you probably need about half a pint total. Perhaps you could buy a small amount from a local liscensed applicator for pesticides and herbecides.

Cut the plant down. Spray remedy at low pressure on stumps. Or spray the stems. Wait for total death and then cut down. Spray the stumps again for good measure.
