Maybe this will help someone but if you wanna kill everything (and I mean everything) put a clear plastic sheet down over the offending area for a summer. It acts like a greenhouse, heating up and sterilizing the ground, killing the plants (as well as the ground bioculture, but it will recover and killing invasives can be worth it).

I wonder if this works for things like Japanese knotweed.

[-] makearmy@lemmy.makearmy.io 5 points 2 days ago

Is the plant in the meme mint? Just deducing from the comments but idk what I'm looking at. 💀

[-] jaykrown@lemmy.world 10 points 2 days ago

Japanese knotweed https://en.wikipedia.org/wiki/Reynoutria_japonica

[-] makearmy@lemmy.makearmy.io 2 points 2 days ago

Word thx

[-] Korhaka@sopuli.xyz 42 points 4 days ago

Fine, I will plant mint instead.

Actually considering mint for the front garden though. It's a narrow strip of dirt surrounded on all sides by 10+ metres of paved land. Hopefully it would be less thirsty than using pots and tbh all that is growing in it currently is thorns.

[-] fossilesque@mander.xyz 33 points 4 days ago

That's the only safe place to plant mint.

[-] Haaveilija@lemmy.world 50 points 4 days ago

I just planted Mint into my computer

[-] fossilesque@mander.xyz 28 points 4 days ago

How is your digital garden now?

[-] 18107@aussie.zone 56 points 4 days ago

It started OK, but now I've got cinnamon everywhere.

[-] W98BSoD@lemmy.dbzer0.com 5 points 3 days ago

Nice.

Not culinary but if you're looking for flowers can I suggest mints more prettier cousins nepeta and salvia nemerosa

[-] Korhaka@sopuli.xyz 7 points 3 days ago

But the entire point of growing something is to eat it. Or be useful in some way at least, considered bamboo for free canes but it sounds like it can damage concrete around it and even clumping bamboo would try and grow larger than the space I have fairly quickly due to the narrow width.

[-] MintyAnt@lemmy.world 7 points 3 days ago

Growing food plants to eat, yes, the point is to eat.

Growing non food plants, the primary purpose is to support your ecosystem. Bugs pollinators birds etc. They rely on native plants only, and need them to survive.

Beyond that people also like the look of flowers and having them grow or thrive over time.

Good on you for not willfully growing something invasive or non native like bamboo (assuming it's not in your native range)!

It would probably need a fair bit of water, too, unless you’re in a more humid climate with summer rains. It is a grass after all.

Unless you planted a tropical clumper, the concrete wouldn’t take damage. A runner would probably pass under it and show up on the other side eventually though. You can stop that by cutting the rhizomes back in summer and fall (think of it like edging a lawn), but it sounds like that space might be too narrow to set that sort of system up well.

[-] Korhaka@sopuli.xyz 1 points 2 days ago

Yeah, that is why I am thinking of planting mint there instead. Should come up with some ways to preserve large amounts of mint when I have it for when its dead over winter though. Mint jelly is an obvious one.

I think mint honey should have a decent shelf life too without requiring refrigeration. Probably isn't that different from mint jelly but using honey as a source of sugar and it isn't set with pectin, which shouldn't really impact the shelf life. Use it like a sweet minty syrup.

[-] BarbecueCowboy@lemmy.dbzer0.com 4 points 3 days ago

If you haven't had bamboo before, can also spread unpredictably and it's more difficult to get rid of than you expect. The varieties that tend to grow smaller are worse.

[-] Seleni@lemmy.world 1 points 2 days ago

Actually it spreads very predictably (in either circles or a collection of straight lines) and if you want to get rid of it, just cut it to the ground and stumpgrind out the rhizomes, which are the only part that can spread the plant (and for most species are found in the top 12 inches of soil). If someone tells you that you need to get out every tiny root, they’re bullshitting you.

[-] BarbecueCowboy@lemmy.dbzer0.com 1 points 2 days ago* (last edited 2 days ago)

I'm speaking from experience, im that guy who said you might have to get out every root. Maybe we were special or maybe it was just the right environment but I started finding it in random patches coming up all over my old back yard. We tried digging it out, burning it, someone suggested tar, but nothing ever quite got ours. I wasn't alone, but I was probably talking to other people who had it bad too. No one complains if everything is fine.

I'm in a new house now, but never again for me.

[-] Seleni@lemmy.world 1 points 2 days ago

That’s because you missed rhizomes, not roots. And if you keep cutting the remnants down after you get the main body of the plant out they’ll starve and die eventually, it just takes a few years.

Speaking as someone who has worked with bamboo for a living for over a decade, an ounce of maintenance is definitely worth a pound of cure. Setting up a proper root-pruning system and cutting the young rhizomes twice a year before they have a chance to spread is much easier than chasing it down after the fact.

Now, tropical timber clumping bamboo… those are tough to deal with once they’re mature. They’re like a boulder that grows lol.

[-] IMALlama@lemmy.world 2 points 3 days ago

We have a thin strip of mint that's exactly what you described. Fresh mint all spring and summer is great for a variety of reasons, plus it smells good. That said, we're constantly fighting runners trying to grow in every conceivable crevice. It tries to grow in the cement expansion joints and in the joint between our house and sidewalk by the door.

[-] Korhaka@sopuli.xyz 2 points 3 days ago

The strip of land is a little distance from the house, tbh the thorns currently growing in it try and come up through the gaps in the concrete or snake their way through the gravel. At least mint doesn't hurt.

Just keep cutting/burning it every couple days. It will die eventually.

[-] Hawk@lemmy.dbzer0.com 5 points 3 days ago

Lol good luck with that!

[-] Wizard_Pope@lemmy.world 5 points 3 days ago

Well we had it in our backyard and did exactly that. It's not there anymore.

[-] Hawk@lemmy.dbzer0.com 2 points 2 days ago

Then you're lucky. Our government tried this and failed miserably. The rhizomes grow pretty deep and are very resistant, so burning and cutting shouldn't really do much.

[-] Wizard_Pope@lemmy.world 5 points 2 days ago

Well if you cut it completely every day or every feq days it will run out of stored energy eventually and stop growing.

[-] Hawk@lemmy.dbzer0.com 2 points 2 days ago

I feel like we're talking about different plants because that shouldn't work at all. Knotweed can survive very harsh condition. Unless you're digging out the rhizomes, there's no way to "cut it completely" really.

[-] Wizard_Pope@lemmy.world 1 points 2 days ago

Is it japanese knotweed? I don't know it might be a different plant. I have no clue what it's called in english but it looks exactly like what we had in our garden

[-] morto@piefed.social 19 points 3 days ago

Let me present you this one:

[-] rants_unnecessarily@piefed.social 15 points 3 days ago

That is incredibly unsettling. What is it?

[-] quinkin@lemmy.world 5 points 3 days ago

Kalanchoe daigremontiana

I know it as Mother of Millions

[-] rants_unnecessarily@piefed.social 7 points 3 days ago

https://en.wikipedia.org/wiki/Kalanchoe_delagoensis

Oh sheesh. Up to 2 meters!

What a nightmare!

[-] morto@piefed.social 3 points 3 days ago

And they tend to grow in any place, including small spaces or cracks in the floor or walls. They spread through different methods and can quickly fill your yard, your street, your house, and everywhere else.

But they also grow a beautiful flower and attract hummingbirds

AMA on how to deal with your invasive plants

[-] anton 5 points 3 days ago

Robinia are taking over unmaintained areas like construction grounds and the edge of the forrest. Some in the forest are full size.
What can I do against them spreading?

[-] MintyAnt@lemmy.world 2 points 3 days ago

Fuckinnn black locust. You're talking about places off your property right? Rough.

One thing is spreading awareness that non native plants are bad and invasive plants are majorly damaging. I think focussing on native plants in someone's home is a great angle. Gardening is something actually in people's control and thus something they would be willing to consider. Notable points I try to get across:

your local amazing bug (e.g. monarch butterflies) will all die without the specific native plants they need to survive
pollinators love native plants more than non native
Native plants are far more interesting than whatever you get at the garden store for looks
Natives are dumb easy to maintain. Especially if ppl just buy partially grown ones. Just help it establish, in mostly the right area, and they will thrive
It's good for the environment. Non natives cannot support our ecosystem and actively damage it.

Beyond that? You'd have to also start specific campaigns against specific invasive plants and go do group attacks on those plants. Your local green organization will usually be good for organizing and getting volunteers, as well as navigating where you can actually go. It's a big effort and a lot of work, especially for such noxious plants like full grown trees. But it can make a difference over time
