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).
Just keep cutting/burning it every couple days. It will die eventually.
Is the plant in the meme mint? Just deducing from the comments but idk what I’m looking at. 💀
Japanese knotweed https://en.wikipedia.org/wiki/Reynoutria_japonica
Word thx
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.
That’s the only safe place to plant mint.
I just planted Mint into my computer
How is your digital garden now?
Now there is Mint not just on my laptop but also my pc and three other laptops :D
It started OK, but now I’ve got cinnamon everywhere.
Not culinary but if you’re looking for flowers can I suggest mints more prettier cousins nepeta and salvia nemerosa
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.
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.
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.
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)!
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.
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.
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.
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.
Let me present you this one:
That is incredibly unsettling. What is it?
Kalanchoe daigremontiana
I know it as Mother of Millions
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
We had one, in no time it was popping up in every one of our pots.
As to growing in cracks, Saxifragales, the order to which Kalanchoe belongs, literally means “rock breaker”. It’s an incredibly morphologically diverse and interesting order.
I didn’t know about that. They’re even more fascinating than I thought
AMA on how to deal with your invasive plants
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?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
People know, it’s just to much work to get rid of them permanently.
Guess I will stick to uprooting the ones I can pull out in the woods and cutting along fences where they hang over.
It really is. I’m not sure we can ever be permanently rid of them too.
My garden patch converted entirely to mint by the end of the warm season. What do?
Is it a small enough patch that you could dig it all out? Mint spreads through rhizome roots, so if you dig out most of the roots, you’ll be able to easily manage any new roots. It’s also just preferable to the poison methods when possible
I can dig it all up yeah. Are the roots easy enough to identify so I know I’ve got them all?
Whenever doing mechanical removal, especially with rhizome roots, you’re not gonna get them all. Don’t focus on that either.
They are like a battery, storing all their energy in the roots for winter and shooting back up during the growing season. If you remove the bulk, you’re robbing the plant of a lot of battery, making it less able to pop up.
You’ll have it come back. But in smaller amounts, which you can just hand pull as they do, eventually totally starving it.
There are certainly ways to find more roots, or times to pull (like rain or after it grows up) or other methods (like a foliar spray), but these all cost more time or include using poisons in your garden. Instead, just dig it, pull as it crops up, and see how it goes. It will likely be enough for less time and let you get into planting stuff.
Also bear in mind: your garden soil also has a seed bank ready to go, so once spring hits you’re gonna get all kind of stuff growing there. If you’re planning to grow your own stuff (food plants or native flowers), then you’ll want to plant those partially grown after you dig, use a mulch for a year or so, and keep weeding. Eventually your planted plants will establish and inhibit other plant growth.
Thank you!
