This randomly appeared in my yard and I’ve been pulling it out etc for 3 years. Keeps coming back.

We had one small patch—I didn’t know what it was, so I just left it. It’s now everywhere. We’ve been digging it up—any other suggestions for getting rid of it for good? I hate it.

You basically can’t. Italian Arum is the spawn of Satan. The only thing that works is to dig very deep around the plant with enough border. Then throw it all away. Period. You have to treat it like a zombie infection. If any small part of the very delicate roots break off it creates more. But you can’t get rid of it unless you dig out the tuber, which is often very deep. The worst invasive species out there besides bamboo. Horrible plant.

Does it respond to roundup? Maybe paint the leaves with a paintbrush so it doesn’t get on other plants, flowers or in the soil?

for those with problems with bishop weed, it's edible and tasty, if that helps.

I was just given this in a seed mix I was going to sprinkle out. Should I avoid?

Nope. That's why it is such a bastard plant.

Yes. I have been battling with it for 20 years. I know I will never completely eradicate it—before we knew just how bad roundup is I tried that and it basically treated it like dessert. It helps to plant things that are invasive that you like more that can compete with it. Lamb’s Ear and spurge are my current favorites as they are easy enough to control themselves. Ornamental grasses work really well, but are very difficult to remove if you decide you no longer want them.

Yup, it has completely taken over a corner of our garden (planted before our arrival). It’s so bad it doesn’t even seem like a plant anymore, more like some apocalyptic sci fi creature (if you’ve seen the Expanse, it’s like that blue biohazard!). The only way to combat it is to just entirely dig up the whole area it is growing in, going at least 9”, and even then you’re only going to set it back a year or two…

White snake root. Love it, great for native pollinators, but it spreads by seed.

pp here. if you can separate it out, i would do so and maybe only plant a couple seeds, and be very careful to not let them go to seed. but others should probably chime in as i never hear other people saying it's invasive, which makes me wonder if it is better behaved for them and just really, really likes me for some reason.

Nope. And I've tried it all.

How do you manage it?
Have you tried removing all the dirt?

I have never had a problem with it, so it just might be that it loves your yard.

If anybody has any tips for eliminating ground elder, please tell me!

Dig deep and don't leave any root behind. Then, solarize if you can; it will kill everything, including possibly the ground elder. Then use cardboard/mulch or arborist chips 6-8" deep to prevent re-growth. Good luck!

See, now, I would LOVE to have those spreading in my yard. I do have violets going crazy but my false indigo barely survives.

I LOVE my violets!

They are an important host plant for a specific butterfly or two. Don't hate on them. I'm putting them everywhere.

are you talking about serviceberries/amelanchier? i don't think they have thorns or prickles. are you speaking about blackberries or wineberries maybe? i personally wish i had serviceberries everywhere, i love the berries so planted multiple plants, almost all of which were eaten to the ground by critters.

This. Serviceberries are great native plants that support a lot of wildlife. Maybe the poster above is referring to a tree that grows in pastures - I'm going to try to find the name - that has horrible thorns. I had one in my yard and we got rid of it.

Another +1 for mint. Last time I let DH install a herb garden.

And Tree of Heaven. My neighbors have a full blown tree - I assume they think it's pretty - but those damn runners go everywhere and never die.

I came here to say "Mountain Mint." It's awful.

+1. I can never get rid of it!

Oh my gosh-- I never realized that I had this. The previous owner must. have planted it. I have tried getting rid of it too, to no avail.
