So the invasive species of plant in my backyard has been properly identified as Japanese Knotweed. It’s been established here for fucking idek.
For those that don’t know what it is, it’s a bamboo like plant that grows 10cm a day and has super invasive properties. They grow in colonies and the root system can be come so complex that it can and will take over land.
So what I was thinking was,since it’s a tree that grows in colonies… Is myco remediation a good idea here?
I read all the ways to get rid of them including introducing a species that eats them and hiring a professional but it doesn’t guarantee that they won’t be coming back. It even says if you concrete the area you can’t leave any cracks because they’ll find there way in and destroy the concrete. They’re able to take over houses too.
They’re edible but… Still!!! They’re highly invasive and don’t ever grow cannabis near them or they’ll be killed by some creepy ass plant that you’ll think is some kind of poisonous plant.
… I wonder if growing cacti near them would be a good idea considering how much water the Knotweed contains… … I just don’t wanna hire a professional.
Says till and glosphate the land but they’re starting to take over my back yard not just my garden. Again maybe myco remediation?
EDIT UPON FURTHER RESEARCH I FOUND OUT ITS AMERICAN POKEWEED BECAUSE IT GIVES BERRIES AND THERE’S MORE OF THE BUSHES IN MY NIEGHBORS BACKYARD. THANK YOU FOR ALL THE REPLIES, THIS THREAD WILL STAY UP FOR THE SAKE ID. KNOWLEDGE
I believe @Future has had experience with invasive plants like wild blackberries.
We have problems with mulberries,blackberries and nutsedge here. The natural way to fight invasive species is cripple, contain and continue fighting long-term to get them under control.
Here’s a quote from @Sidco_Cat , the spiritual mom of the forum:
Once you rip out the knotweed, create a lacto-fermentation from the plant matter. At 5ml/gallon drench and foliar, it is an organic and systemic IPM for powdery mildew with cannabis.
EDIT: Sorry for all the edits, this thread just got all sorts of juices flowing for ol’ @AgTonik . . . I would love to create an organic “super fertilizer” for plants that contains moringa, knotweed and a less refined version of AGT-50 Fulvic Mineral Complex that contains carbon. I’m going to make a separate post about it in one of my fertilizer threads.
Bananas are also the same way if let them become established. I would think that tilling would be the easiest option, and you’ll probably have to till it many times in a season to adequately break up the root system.
Tilling will break up the rhizomes and you just end up with a million tiny ones that are even harder to get rid of, @Sidco_Cat approach is as much a life lesson as it is a gardening tip
You need to hire a professional to get rid of that shit. It won’t be an easy task either, as you well know. You also know it will devalue your property. I’ve seen another type of knotweed in Thailand. There are insects that attack it, but they cant do it alone. That is some scary shit. It’s like water. it takes the path of least resistance. I’m sure I’m not telling you anything you don’t already know. However, that shit can render land worthless if not killed off. btw, what state are you in?
I the only simple way I’ve ever found to remove well established invasive plants is to cut it all back to bare ground, break up the ground a bit with a pitchfork and then torch it. Followed by heavily mulching the area with wood chips and pulling anything that tries to pop up.
Pretty much the only thing I can say is good fucking luck. I have had a patch in my dads backyard for as long as I can remember. We have tried removing, tilling, poisons, burning, you name it. Since then they have even dug it all up and regraded the yard and about 6 months after laying new sod a few shoots popped up. So they continue to just yank them out as they pop out but overall it’s still there and still not going anywhere.
Removing blackberries is a walk in the park compared to Japanese knotweed.
If the patch isn’t to big dig it all up and follow every shoot you can until you find no more and then go out past that a few feet and recheck. Take all the dirt you dig up and don’t reuse it anywhere or expect more shoots to show up wherever that dirt is put.
So you got to it early in the season so you shouldn’t have a hard time. Basically at this point you just want to starve it of resources. Chop it down so it can’t produce energy then cover it up with a tarp or something to keep light out. Weigh it down with rocks/bricks/jars of red D8 and basically just prevent it from ever growing. Doesn’t hurt to go in and give it a good ol’ stomp every once and a while. I vaguely remember environmental groups holding “Japanese knotweed stomping parties” to basically have a hoedown on top of a patch of it to basically trample it.
I do not remember if it can reroot but it’s not a bad idea with any invasive plants that you remove to bag whatever you cut into thick contractor bags and tie them off. Leave them in there for a while to dry out and reduce chance of rerouting. Some invasives are notorious for being very resilient so you pretty much need to bag them up for weeks or so things like lay them out in direct sunlight in the summer.
Well now I’m at a loss because I cut down a bush with my girl this year and that bush uslaly fruits berries and I looked it up and it said its American pokeweed.
First pic of the little stalks looked like knotweed. When I’ve removed it at an old job they just told me to go to town on it with a brush cutter. Pretty much just ripped it to shreds. I think after that they just had a group of volunteers go and stomp it out on foot. I honestly can’t remember if they bagged it up or just let it decompose right there but usually the norm was to bag it so it doesn’t root elsewhere. Some came back the following year but barely any.
First patch was huge. Probably about the size of a 2 bedroom house. Basically a little forest of the stuff. The bamboo-like stalks are no match for the blade attachment on a brush cutter so I think I knocked the whole thing out in a day or two. Actually was kind of fun to mow down.
This might be a good excuse to buy a brush cutter. You can get a decent one for two-three hundred bucks that will have no issue ripping through knotweed and realistically anything you don’t want sprouting up in your yard.
Pokéweed. I don’t know anything about that other than the name is cool.
