The weed that can't be killed...

Posted by AmandaMI zone5 (My Page) on Sun, May 2, 04 at 11:00
| For as long as I can remember, there has been these "weeds" that pop up constantly in my mostly-shady bed by the house. They are even in the cracks of the sidewalk near there, and even under the house! I mentioned it to my mother yesterday, since I know she battled it when she lived here, and she said it was not a weed, but a plant that someone planted before they bought the house almost 30 years ago! Despite pulling it, spraying it, trying to smother it, for almost 30 years, it lives. She said it was called snow-something, so I searched around on "snow", "invasive" and "underground," since that's how it spreads, and I eventually found it. Aegopodium podagraria: snow-on-the-mountain or goutweed. So yes, someone actually unleashed this beast in my garden. I tried smothering it this year with several layers newspaper and a heavy layer of mulch and it worked for about two weeks, but we've had a couple days of rain and more of these things are bursting through by the minute.
How can I kill this stuff without killing everything else in the bed? |

You can't By now that plant is probably so established that you'd have to excavate something the size of a swimming pool to get all the bits and pieces. Try digging one of these up by following its root system. I'm pretty sure they end up somewhere in the earth's core. Just trying to sound glib. I'm doing battle with dozens of baby rasberry canes IN THE LAWN. We all choose our battles.... C. |
RE: The weed that can't be killed...

| Sounds like Aegopodium. Try entire overlapping sections of the newspaper. |

| LOL, Chris...I actually have considered tearing out the entire bed and digging each one of these things out by hand! But can you imagine, after all that work, the feeling I'd get when it popped up and waved at me yet again?! My mental health is very important to me, so I won't go that far...yet. ;) I just about fell over when my husband crawled under the house to fix a pipe and reported that this stuff is growing under there! I guess that the parts that see the light on the other side of the foundation are feeding the parts that live in the dark. I considered, briefly, setting it loose in the backyard under a huge tree that nothing grows under. But then, I considered that, 100 years from now, some poor soul might want a shade garden there, and I could be setting them up for a nervous breakdown! |

Roundup. You won't get it by weeding & you'll likely have to spray it multiple times. |

Last summer we build a 12x16 family room onto our home. I dug out all the GOOD plants and left the snow on the mountain for the contactors to deal with...they had to excavate the area..they tramped on it...plastic was put over ground to stop moisture and the addition was BUILT over it. Several months later, hubby had to go under to run some phone line...guess what was still growing!!! I keep watching for it to come up throught the floor boards and carpet! I do think that stuff came from outer space on a meteor or UFO. Probably a UFO..their idea of a joke on us for sending all those signals into space. My advice to you....MOVE..LOL April |
RE: The weed that can't be killed...
| | |
| Yeah, you can't get rid of it. But you can crowd it out. I successfully did this with daylily, ferns, and hosta. |
RE: The weed that can't be killed...
| | |
| I don't know the first thing about this weed, but if it has an interconnected underground root system something I have heard others report success with is taking concentrated round up, putting it in a container and placing a portion of the weed in the container. Obviously you are going to want to rig something up so that the container doesn't spill onto the lawn. The idea behind this is that the plant will continually drink the round up, it will travel the entire root system eventually and the entire plant then dies. I have read of success with this method in eradicating bindweed which is another perennial weed that roots extensively. You may find that this method kills some, but not all and that would be an indication of seperate root systems. Just repeat where necessary. |
RE: The weed that can't be killed...

I've used Roundup on all kinds of weeds. When they are close to other plants, I use a small paint brush. Sometimes I had to 'paint' it a few times, but after a couple of tries, it would die. I never use a spray with Roundup, I'm too afraid it'll get on me! They say to use it on a calm day, well we have very few calm days. So 'painting' the weeds has worked the best for me. Good luck on getting rid of it! Kat |

| Hey, I got this idea at another forum. If you spray with round-up cover the other plants in the area with buckets until it has completely dried. |

| I agree with a number of the previous posters. I would use round-up. I would paint it on as suggested. This will have to be repeated several times throughout the year, and possibly for a couple of years. That is exactly how I am treating what was originally a very bad infestation of poison ivy. Now I have it down to just a few tips coming up. Hopefully this year there won't be any, but I am quite prepared to "do it again" with that pest. I know it is a pain in the ..., but a lot less energy will be expended than diggin up the entire bed. |
RE: The weed that can't be killed...
| | |
an alternative to spraying round-up is the Hand of Death. Put two nitrile gloves on. dunk your hand in a bucket of round up. Grab the plant, and say thrice: "I smite thee with the hand of death!" Works everytime. (and so does the paintbrush, but not as much fun.) |
RE: The weed that can't be killed...
| | |
| LOL, Bug Girl! My neighbors will be so impressed. Just for fun, I'll wear the gloves everywhere and threaten to smite anyone who offends me. ;) Thanks all! Round Up it is. I'm almost going to enjoy this... |
RE: The weed that can't be killed...
| | |
| I realize it is late to post on this but I can not resist. If anyone has watched the bbc series 'How to be a Gardener' Alan Titchmarsh makes similiar comments about a persistent weed and the punch line goes "You may eventually weaken it, or you can simply move house!" I have a running battle with perennial Morning Glories which I did to myself although I would love to blame someone else. |
RE: The weed that can't be killed...
| | |
| oh my goodnes. lol. i smite thee with the hand o death. i love it!!! |
RE: The weed that can't be killed...

| I can sympathize, my neighbors planted it along their 6" strip between their driveway and the property line (where my beds start!). I can't believe they hate me that much....but they did it. My beds are fairly new, so last fall I layed down 6-8 layers of overlapping newspaper and 4" of shredded hardwood mulch over everything but the trees, shrubs, and newly planted perrenials... This spring the Aegopodium podagraria acts like I did it a favor! It has completely infused itself in the beds. So much for smoothering. At this point, I'm scared it's going to run across the lawn and I will simply have a full lot of it! Current strategy is cut it to the ground every time it gets more than 4" tall AND plant as many other plants as I can...hoping to squeeze it out. Having completely graded the lot, amended the beds, planted sod, 15 trees, ~60shrubs and ~300 perennials...I am not taking it all back out to excavate! And the whole Round-up thing is not part of my vocabulary...I want to use the least amount of chemicals as possible (birds, bugs, animals, water table, you name it). So, in a sense I am giving up. Sigh. But I will continue to hack at it until the rest of the plants have matured enough that my yard is not dominated by it! Oh yea, my F'n neighbors moved. They didn't want to "wait for MY yard to mature". What kind of crap is that! Ironic part is the new neighbors are 100% cluesless about landscaping and could care less what I do with the 6" strip that is theirs...crazy world! M.J. |
RE: The weed that can't be killed...
| | |
| Believe it or not, I got some Aegopodium from my mother-in-law under my maple trees that I need to ENCOURAGE! It's been there eight years, and barely fills the space. So, I guess if you give it good enough competition, like a silver maple, it will stay contained. But come to think of it, this stuff always stayed neatly where my mother-in-law planted it in her yard. Never bothered the neighbors, tho' it could have. I guess she brought it up right! (Thanks Mom!) Must be an unusual variety. |
RE: The weed that can't be killed...
| | |
| I have some of it growing around the base of a tree. It is no big trouble for me to keep under control. Honestly, a lot of people freak out about these supposedly impossible to control plants and then they have a lawn. Well, guess what? There is no plant that is worse for rhizomous spreading than turf grass. And then we go and fertilize and irrigate it! Go figure. More than half of my weeding is removing turf grass from where I don't want it. |
RE: The weed that can't be killed...
| | |
| We have both the variegated variety and the plain green variety of goutweed. While we will probably never get rid of it, we go out every day and pick anything visible. (Sometimes I eat it -- it is a potherb and tastes a bit like lettuce. My Chinese neighbours use it that way all the time -- also as a medicinal herb.) In the spring, I almost wept. It was my first year in this house and I had no idea what slept under the snow. We picked it all. It grew back. The ferns and solomon's seal started. The goutweed overwhelmed them. We picked it. It grew back. Then gradually the plants, mainly the ostrich fern, solomon's seal and hostas, overshadowed it and it is now not a problem -- until next spring -- or maybe sooner. The mulch makes it easier to spot when it does raise its little head. MMMMM salad. Joanne |

RE: The weed that can't be killed...
| | |
Wow! This was fun to read! I smite thee with the hand of death?!? Great -- I'm adopting that one to deal with the misc. weeds that waft into my back garden from the school yard behind my house. And I'm NOT planting any goutweed. |
RE: The weed that can't be killed...
| | |
| Eat it? My son's bunnies love fresh greens, dandelions and the like. Maybe we have a new treat! |
RE: The weed that can't be killed...
| | |
| When we moved to our home, there was already goutweed planted under our lone evergreen tree, fenced in on four sides by the sidewalk, street, and driveways. People freaked out when they heard about it, but it doesn't spread at all when contained by the concrete. But like Braveland, I need mine to do better. Every summer, a brown rust or something starts in one small spot and gradually kills the whole plot, so that by this time in August it looks really yucky. The first year I bought some goutweed seedlings to repopulate the area, but it wasn't necessary - there's always new little seedlings under the dead ones, waiting to take over, but it sure looks crappy for awhile. Any idea what's doing this? The neighbors have some along their house, which their ferns and solomon's seal seems to keep under control, but theirs never dies off. Maybe I should just rip it up and put in something that will do better under an evergreen. |
RE: The weed that can't be killed...
| | |
| Nornster, mine has the rust this year too. On another forum I saw corn meal being used to control fungus, so maybe I'll try that. The new sprouts don't have it yet, so I might just get my butt out there and cut all the affected ones off. My yard has a lot of fungal diseases this year- wet spring, not thorough enough fall leaf clean-up last year. I plan to do better this year. Good luck with yours! |
RE: The weed that can't be killed...
| | |
| I GOT RID OF MY GOUTWEED!!! There is hope! It was here when we first moved in, but it's all gone now. We also had the dreaded bindweed in the back. I sprayed both with Round Up. It took several sprayings, but I did get rid of the goutweed eventually. The bindweed, however, is absolutely rampant all these years later and none of my neighbours are doing a bloody thing to control it... Do you know what boils my blood? Goutweed is commonly sold in the big box stores and even some garden centers, as "Bishop's Weed" or some other variation. Appalling! |
RE: The weed that can't be killed
| | |
| Yeah, but Stellagord, bishop's weed, or snow-on-the-mountain, or goutweed, isn't a problem at all when it's contained, like in a planter box. There was an article in the Chicago Tribune talking about invasive species, and the park district said goutweed's not a problem if the roots can't spread. They plant it all the time under trees, surrounded on all sides by concrete. I bought some at a garden center to replace the stuff that died - as long as I knew what I was getting into, I don't think it's bad. Braveland, could you post a link to the other forum talking about using the cornmeal? I've had a wet summer, too, and there's all kinds of mildew and fungus in my garden, too. |
RE: The weed that can't be killed...
| | |
| Nornster, yes, I would imagine it's totally controllable in a pot or planter. I guess a person would have to make sure its branches didn't touch the ground and start a renegade colony in the ground. (I have planted my mint in the ground, but inside huge pots... Of course, it escaped and now it's growing everywhere...) |
RE: The weed that can't be killed...aka 'The Thing'
| | |
| It's so funny to think of mint "escaping" from pots...I just picture a little mint plant, dressed like a prisoner, plotting its getaway. Wasn't the alien in "The Thing" (or maybe it was "The Body Snatchers") really a plant that was trying to take over the earth? Maybe it was a goutweed from another planet :-) |

| I can't believe I've missed this thread! I had the cursed stuff come in via a plant exchange. This has led to my current quarantine rule for any plant coming in from an unknown garden. I fought this stuff for years until we moved. I would guess it's still there and taking over. Last time I drove by the old house it was pretty obvious the current owners aren't gardeners so I suspect it's been free to do it's own thing for the last five years. Can you imagine that? There's probably mint in the lawn also! |
RE: The weed that can't be killed...
| | |
| Hi there. I probably bought your old house Janet. The stuff has completely taken over my ENTIRE yard. There is about 7 feet from the road to my front "garden" (which is also full of the stuff) that is grass. My husband and I just bought the house this April and when all the snow finally melted there it was. I tried Round-Up like everyone says to, and what I actually sprayed has brown spots but didn't die then about a week later there was new shoots popping up. And when I say I sprayed it, I'm talking 3 and a half gallons of Round-Up on about 250 square feet!!! It killed what little grass I have real nice though. So if anyone has any other ideas it would be great. I have heard garden lime might do it, but I don't want to waste my money if it won't work. PLEASE PLEASE PLEASE let me know. :( |

| So that's what my sis has growing in a small patch along her house. Kind of a bummer -- it is a rather pretty thing. I know the previous owners made no effort to contain it. That being said, it doesn't appear to have misbehaved. Wonder why? It certainly isn't in a container. |
RE: The weed that can't be killed...

| Someone gave me this "potion" (I collect 'em) and it looks like something you can possibly use. POISON IVY KILLER 1 gallon water 1 cup salt 8 drops liquid dishsoap Mix together and spray on the offending nasties. Good luck Kiwi |
RE: The weed that can't be killed...

| Hi! I will line my future flower beds with pond lining - black rubberish material along sides about 30 cm deep. so roots from outside wont come in. Then for 1 summer pick out all roots inside bed. The rest is lawn - frequent mowing kills it. |

| There's a picket fence dividing our back yard from our neighbor's. On our side of the fence there's a 10" strip of garden and then sidewalk - it gets full sun. My neighbor has snow on the mountain growing and likes it. Last summer I dug all out that had spread into our 10" strip. Then I dug out all the soil and inserted upright sheets of stainless steel as deep as I could get it along the fence line - at least 8" deep. I kept my fingers crossed that this would stop the roots from spreading. Wrong! It's on it's way back in our yard. I'll be digging it again but with the neighbor letting it go, I think this is going to be a losing battle. I hate this stuff. |
RE: The weed that can't be killed...
| | |
Has anyone tried smothering it with landscaper cloth? I'm going to try it with adding mulch over top of the cloth. Also what are effective ground cover combatants that will crowd it out ? One I know of is English Ivy, but that is trading one problem for another. Would sweet woodruff crowd it out ? This weed should be called "The Devil's Weed" |
RE: The weed that can't be killed...
| | |
| This is an incredibly funny thread and should be revived here in 2010. I too had a tiny patch of this alien under a 50+ year old silver maple, which had to be taken down. I foolishly let the small two foot by 4 inch high patch survive. I have been doing penance for six years in an attempt to keep it from taking over in a FULL SUN, unwatered area in our very xeric climate. Today I am going out there to paint roundup on those leaves for the fourth time this month, but this time I am taking our full spectrum light and holding over each section for about 15 minutes at close range. I remember that roundup requires sunshine to encourage the victim plants to take up the active ingredient. It "worked" on a small patch when I roundup-nuked the whole patch last month. It is important to cut off the flower stalks, too, before they go to seed before, during and after you nuke it. Remember to wear sunglasses, gloves, long sleeved shirt and pants, socks and solid shoes for yourself, you don't want to get sunburned. Also remember to have your spouse or neighbor take pictures of you as you do this in 90 degree weather. These will form the instructions to future generations at your home in how to combat the aliens at ground level (Note, not WIN, but only combat) and provide your progeny with proof that you are insane. I will add the intonation of "I smite thee with the Hand of Death" as I perform this ceremony in full ceremonial dress and think of each of you as I do so. Tell Ma, I died game. |
RE: The weed that can't be killed...
| | |
| What fun! I love "The Hand of Death." I have a lush stand of Bishop's Weed. The story is that monasteries used to keep herb gardens for healing, and in one area goutweed became called Bishop's weed. Got gout? Go to the bishop for some weed. I got the stuff to put in the ditch so I wouldn't have to mow over all the rocks the snowplow threw. It didn't make it to the ditch...my son-in-law "helped" me by planting it on the north side of the house. He then mowed down my Canada anemone (it was in full bloom, but mixed with grass) which killed it. So now instead of wildflowers I have a lovely bed of snow-on-the mountain. So far it hasn't crossed the foot path; I guess it can't take foot traffic. (I haven't dared look under the house.) I do like the somewhat spicy taste, and sometimes nosh while I work in the garden or put it in a salad. I haven't gotten around to trying it cooked like spinach, but I guess I'll never starve to death when I have goutweed around! |
RE: The weed that can't be killed...
| | |
Our home had it, and we did get rid of it. Dug up the area and pulled and raked out all the roots of it. If you have 'good' plants, then put them aside, shake out the dirt and put them back in the garden when you are done. After that, pull EVERY hint of gout weed the minute you see. If you did a good job of raking and sifting, this won't be too hard. As long as you go after any stragglers, you should be successful. You'll need to be vigilant for a few years and look under plants to see if it's re-establishing itself in secret. I am a LAZY gardener, so it's not as bad as it sounds. |

| This is so funny. A friend tried to offer me a shovelful of this plant many years ago, I told her if she brought it to my house our friendship is over. Recently on a walk DH commented on how pretty a patch of it was in a neighbor's yard. I pointed out to him how it was the only plant in the huge bed, and told him if he ever planted any in our garden we are through. We wouldn't really be through, but would require marriage counceling to get over it, along with all the above advice on how to get rid of he noxious weed. |
RE: The weed that can't be killed...
| | |
| I have several areas in my yard where I grow bishops weed intentionally. It is a great ground cover where other things won't grow. Three years ago I decided to burn a pile of leaves right in the middle of one of my bishop weed beds, figuring you can't kill it. Well, I still have a large round black area with no new growth where I did the burning, so I guess fire is a good control for this weed! |
RE: The weed that can't be killed...
| | |
| We've covered a slope with yellow archangel (lamiastrum galeobdolon) and have this bishop's weed come up in isolated clumps every now and then. Round up! We obviously don't get it all, because every summer we round up a clump or two. It's the Solomon's seal getting invasive now, and we just pull it all summer. May have to round up that, too, before it takes over. |
