Committing Herbicide Against a Yucca Plant?/Vanity

Okay, I know there has to be a way. There just has to be.

We moved into our house 5 years ago, and the previous owners planted some yucca plants. I want to be rid of these...FOREVER. I have tried each year, several times, and I have tried a LOT of different things to kill them, and the darn things just keep coming back!

So far, I've tried:

~Digging up the plants' roots, to a depth of 3.5 feet. They came back.

~Putting boulders on top of the plants. They came back.

~Pouring Round-Up on the leaves. Unfazed.

~Drilling holes and filling them with gasoline. Plants came back.

~Chopping them to the ground, covering with thick black plastic. Plants sent shoots out the sides.

~Cursing them.

~Burning them.

I have HAD it with these plants! Please, if you have any suggestions or can tell me what has worked for YOU, I'd be so grateful!

Oh yeah, the little boy next door was potty-training and couldn't make it inside, so I asked him to pee on the yuccas. Nothing.

I think I hear them snickering every time I walk by.

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.

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.

Two words....Copper Sulfate.

Up here, the nemesis is burdock. I have tried everything you tried on the yucca for decades and the burdock comes right back. They have taproots that go all the way to hell, they survive years under black plastic, they wilt momentarily from Roundup.

I have planted mint and Bishop's weed after digging them up and both highly invasive plants do not totally crowd out the burdock.

Since they are growing in areas I am filling with flowers, I am reluctant to try salt,

I will monitor this thread for any good ideas.

Mike, I am not sure you can get rid of kudzu. But maybe if you plant burdock? Just kidding. However, I just had a thought: porcelain berry! It is highly invasive and in warm zones (5 and higher), it covers everything, just like kudzu! However, it has pretty fruit in a variety of blues (it is an Asiatic grape family plant). There is a less invasive variety that is variegated, named Elegans. Just a thought. Up here in the North, people plant it on fences and have to be diligent in pruning it back. I only grow it in containers, though. Birds like the fruit and spread it far and wide.

LOL! Oh you're cruel! :o)

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

So how exactly does a dead cow in a clear plastic bag kill a Yucca plant?

[Basselope]

ACK! There it is!! There it is! OMG, are you outside my house right now, taking pictures of these vile weeds?!?!
