I'm fairly sure that if I put an addition to my house, over the spot, I'd just end up with a new plant in my living room! Also, wherever you nick the root, it will sprout a new plant. This is how 2 become 8 that become Straight out of Greek Mythology! Don't EVER plant the crap! Learn to live with it and plan your landscape around it. Embrace the dark side. It's not hard, a spray here and there and no water, but we sacrificed SIX summers of an ugly dead patch instead of a flower bed.
When we first bought this house years and years ago there were three large clumps of Yucca flaccida, the ugliest and poorest excuse for a 'decorative' yucca in the country in my opinion, the floppy one that will grow where others won't because its a SE variety and will survive in wetter climes where the really cool dramatic kind won't. Rather than a nice sculptural yucca, this eastern type forms thick, messy thatches of dead leaves combined with limp, drooping green ones making it an UGLY yucca as far as yucca's go for landscape purposes.
It really looks like hell once it forms a big colony unless you kill yourself trimming it up often and cleaning out the stuff that blows into it. We could have had three nice sized ponds installed once the digging was done if we'd purchased liners no thanks but it taught me to be leery of yucca since this yucca was just a common non-desert flacid flaccida.
My Yucca rostrata that has gotten infested with spider mites for the last 3 years got a drastic burr haircut so I could attack the mites with alcohol and is coming back around to its beautiful blue self.
Its a very pretty type, single trunk and doesn't form a colony. Mites only attack in spring. I chose not to dig it out but I'm sure it would be impossible if I'd tried. By the way, drowning with water seems like a better idea than depriving it but I doubt it would work either in a suitable climate like Utah. Just as bad is Trumpet Vine. NEVER plant that in an average yard or anywhere close to a building.
The roots travel long distances and the more you try to get rid of it, the more vines you will have springing up everywhere, nothing will kill an established vine. Then there is running bamboo So, I took what I could from this post, and tried something a bit different. I cut out all the leaves, and then had at the root with a hatchet. I know, that should create more of a plant, but I added a step. I drilled a hole in the most vertical root stalk I could find.
I then inserted a small funnel that could hold about three tablespoons of liquid, in my case, bleach. Because the yucca seems to use capillary action "backwards," I let gravity to the work. Just let it sit for about ten minutes and the bleach did finally go into the root. Stay tuned Years ago I was in charge of the flower gardens at the church. A lady brought me a small yucca from the pasture behind her house. She wanted me to plant it because the Indian name was Candle of The Lord.
I did. It grew and grew and grew. Soon it covered our church sign. People wanted it GONE!! On a good day after it rained and the farmers couldn't work in the field, one kind fellow came with a tractor and a log chain. He fastened the chain around the bottom of the plant, and pulled it out with the tractor. It left a hole big enough to bury someone. There was as much on the bottom of the plant as the top. It never came back.
Some farmers clean their pastures of yucca with this method. In March I posted my failed attempts to kill my Yuccas. Another year on these monsters are still living happily underground and continually sending out shoots. Beware all who plant one of these creatures from Hell - they are immortal! I really believe along with cockroaches these things would survive a nuclear holocaust.
Fortunately I am selling my house and moving country. As suggested by a previous contributor I will not leave a forwarding address and will definately check any of my garden tools and equipment for any minute traces of these brutes. I chopped it down but with in a week it had spouted new shoots from the stumps, I tried all the ways to kill it possible and decided digging up the roots was the only option One huge tunk that just will not budge. Has anyone ever come arcoss somthing like this before?
Any suggestions how to move forward? I believe I successfully managed to remove all the fleshy roots in my yucca removal project, had to dig 6 feet to get everything, all that is left is millions of the small pipe like roots going all over the garden, I assume these will not need removing? I'm planing to spray strong herbicide all over the hole just to be safe.
Paint the undiluted herbicide on the leftover roots' fresh cut ends so that it goes where it needs to be effective. Spraying it all over the hole will just have it washing into the groundwater and won't effect the yucca roots much. I have a few unwanted Y. I plan to try something that no one else has suggested or mentioned trying.
I'm going to get some enamel spray paint and get all artistic on the darn things. I'll just spray both sides of all leaves and when new leaves come on, I'll spray those. The only thing I haven't decided is whether to go with a natural-looking green, jet black or neon hunter's orange. Seriously though, I'll probably go with the green. We haven't seen any shoots in years! We used a combination of really digging it out with a maddox and concentrated Round Up.
We didn't notice any thick roots coming off the 'trunk', just the stringy ones you see in last pick. My husband has been repeatedly pouring on gasoline as soon as we saw a green shoot all of last summer. I dug around the yucca several times and discarded what I could find. I figured that the slimy mess was a good sign. By early fall it seemed to have worked. Spring should be coming soon, so we'll see!!! I found this whilst doing some research before trying to attempt what sounds like an impossible task.
Before reading the thread I had already drawn up plans on what was going to go in its place but after having a good laugh here I think my plans for a meditation spot is not going to happen anytime soon although I think I will need it. The below picture is pre-removal and the tallest of those devils is probably m tall. Over the past few weeks I have removed about half of those suckers limited bin space but with a green waste collection I am attempting to finish off the job this weekend.
The root source is actually at the bottom left of the picture and there are more towers to the left :. I remain hopeful of success but I may never be the same person again. If I don't post again, please avenge my death against these hateful wastes of space.
Thought maybe you were onto something, but no I've done all this before. It will kill down the tops, but next season there they are again. I've been told that weed killers do not kill bulbs. There are a couple that are more powerful than roundup; but they are dangerous because they can damage nearby plants just by being in the soil. Imazapyr and Pramitol.
Probably should only be used by professionals. If you only have a small area of bulbs, why not just cover them with black plastic and mulch for a few years. Surely THAT will kill them? I have lost track of the years this has been going on, but at least 30 and maybe more. I'm now 83 and tired of it all.
If I wasn't so old I'd move. If there was a market for these I'd be a billionaire. One year I covered a whole bed with plastic and let them cook. Killed everything but those SOB's. That was the summer we had 54 straight days of over degrees. Thanks for trying to help.
Well, I think SOB's must have been here since the beginning of time, like cockroaches and coyotes. Yuccas LOVE and need sun. Remove Yucca and cover area with mulch or a tarp. When new shoots emerge from root fragments remove immediately so plant gets no sun. Roots will die quickly with no sun. I had a huge yucca removed but there is a pile of sawdust left. Can I use it as mulch or will that mean more yuccas will grow? I live in Tacoma, Washington and since October to-date June 7, , we have had over 47 inches of rain.
Believe me, drowning yuccas in water does not kill them at all, nor does the lack of sun. In fact, the 10 clusters of plants growing in our small gravely yard are stronger and more prolific than ever I finally killed some yucca with relatively little effort: in March, just when they were starting to actively grow, I cut off all the green stuff, leaving a stump about 3 inches or so high.
I used a cotton ball to dab it on with. Those suckers died immediately. And I was able to kick away the dried-up stump in about 6 weeks. I couldn't believe how easy it was. I would imagine that I removed a couple of wheelbarrows of roots. I left the hole open for a month or two with no new shoots, so I filled the hole in with sifted dirt. I have planted nothing in it's place, and I check literally every day for shoots.
I find a few every week, and use a trowel to dig them out as deep as the trowel will go. None have ever reached 3" in height, so depriving them of sunlight does not work. When it cools down this fall I will be digging the hole out again, and will again sift for any pieces of root. What a nightmare. I purchased my home over 2 years ago.
At the time, I knew very little about yuccas,let alone how difficult it would be to remove. There were 4 yuccas growing along my fence line. They were huge! I knew that I wanted them gone but I had no intentions on digging and cutting away at it. I read that few have had success with brushing on weed killer so I decide to try another method. I cut them all down until about feet were left above ground level. I then drilled deep, in wide holes in the different stems coming from the stump and drilled holes into the stump itself.
After, I filled them with concentrated weed killer. Specifically weed killer high in glyphosate. As days and weeks passed, I saw leaves and sprouts on the stem and trunk turning brown and dying. Keep checking and repeat the process as many times as needed. Be prepared to practice patience, as it may require up to two months until the baby Yucca plants stop showing up no matter how well you do your job. Start from the top, cutting branches and smaller stems all the way down to the ground.
Pull out any smaller root close to the plant. When only the main stump is left, cut it down. Use an axe or saw, or pruning shears depending on the size of the Yucca plant. Next, measure a circle three feet wide around the base. The Yucca has a big and wide root system, and you want it all out. Marking the area before you start digging goes a long way in ensuring you remove enough of the plant and its roots.
It is very important to get most of the roots out of the ground while you are digging. The surest way to do so is to dig your hole at least three to four feet deep. Start from outside of the marked area and shovel down towards the base of the plant. During the process take out every part of the routing system that you spot. When the stump and the attached root systems are all removed, double-check the area for stragglers.
Remove the leftovers if there happen to be any. If there are any roots hiding deeper in the ground, exposure to the sun will eventually dry them out and kill them. Keep in mind that controlling yucca is not a one-time job. Livestock, wildlife, wind and water spread the seeds far and wide, so you will need to search for unwanted seedlings periodically and kill them.
Professionals with Texas AgriLife Research and Extension Service have developed, tested and approved these yucca control methods. Your results may vary, but you should be able to kill about seven of every ten plants treated.
