#MeshTech: A New Strategy for Managing Knotweed

February 24, 2026

"Knotweed (#Reynoutria spp.) is a severely invasive plant originating from Eastern Asia. Introduced to the East Coast in the late 1800s as an ornamental, knotweed has since become ubiquitous across North America, reaching over 40 US states and 8 Canadian provinces. Knotweed has proven extremely detrimental to a wide variety of ecosystems in which it has established. Forming tall, dense thickets, knotweed shades out native plants, preventing them from growing. Additionally, knotweed is #allelopathic, meaning it releases organic compounds into the soil that inhibits the growth of native plant species.

Knotweed also increases erosion along streams and riverbanks. By shading out native groundcover species and reducing the diverse root reinforcement provided by native species in riparian zones, riverbanks lose considerably more soil when infested with stands of knotweed (Hammer 2019, Matte et al. 2021). This erosion can increase turbidity of waterways, potentially affecting fish and other aquatic species (Henley et al. 2000). The reduction of native plants in riparian zones paired with winter dieback of knotweed stems also leaves riverbanks extremely vulnerable to winter and early spring flooding. This degradation of the riparian area creates a feedback loop in which floods carry knotweed propagules downstream, where they can colonize and increase erosion in new areas (Colleran et al. 2020).

Historically, management of knotweed has been extremely time-and-resource intensive. Large populations require years of consistent treatment, often combining mechanical and chemical approaches to be effective. This commitment to diligent, multi-year mechanical treatment can be discouraging and can lead many to abandon treatment plans before completion. However, a new knotweed management technique could reduce labor inputs.

Developed by Dr. Eric Donnelly, the MeshTech management technique has produced promising results at managing the growth and spread of knotweed while dramatically reducing labor inputs. This method involves cutting knotweed stems down to the soil level and laying -inch galvanized steel hardware fencing over the cut stems. When knotweed resprouts, it grows through the openings in the fencing. As stems mature and thicken, the metal fencing will begin to cut into the stems.

The knotweed will continue to grow through the fencing, effectively girdling itself at its base. This method aims to impact knotweed's nutrient pathways while also damaging the structural integrity of the plant. Alone, this method cannot eradicate knotweed populations. However, the MeshTech method can potentially reduce the health and vigor of knotweed, thus reducing the amount of cutting required in a growing season and the rate of spread in an area.

At the #PleasantHillPreserve in #ScarboroughME, the #ScarboroughLandTrust (#SLT) has begun implementing the MeshTech method to manage a portion of their knotweed infestation. An effort led by SLTs #Stewardship Director Sami Wolf and Nathan Hjort, owner of Absolutely Complete Property Services, initial results indicate that the hardware fencing is proving successful. The knotweed forced to grow through the hardware fencing at Pleasant Hill Preserve showed clear signs of strain. Stems demonstrated significantly stunted growth and had even begun flowering early, an indication that a plant is under stress. While knotweed struggled to grow through the -inch holes, #NativeFlora had begun to sprout up through the hardware fencing. Other knotweed management practices, such as #tarping or mowing, often discourage the growth of native species in a management area. Over time, the presence of native flora could provide an extra level of #BioticResistance that could help slow the growth of knotweed and help kickstart #NativeRevegetation efforts. Eventually, supplemental plantings of native woody species can take place by cutting openings in the fence to allow for these larger species to grow. The fence can also be easily staked down, preventing knotweed or moving water from moving it out of place.

It is important to note that knotweed is a resilient plant and there is no single management action alone that will completely eliminate a population. The most effective knotweed management strategies use creative combinations of multiple approaches. Knotweed is a rhizomatous species, meaning it has an extensive, underground nutrient storage system made up of horizontal rhizomes that store nutrients. Draining this underground nutrient storage is the key to effectively managing an infestation. Consistent cutting of knotweed forces the plant to exhaust its below ground resources. By combining a cutting regimen with the MeshTech method, land managers could potentially see a significant reduction in their management timeline.

The effectiveness of this method provides promising implications for the future of knotweed management in Maine. Paired with consistent management, the MeshTech method could provide Maine with another tool to mitigate the spread of knotweed and reduce our reliance on chemical treatments."

My 3rd #VietnameseCoriander container is now totally full of happy plants! I propagated these ones from my main repurposed bathtub planter, in June. They are left outside in Winter & they survive through snow/ice. We harvest them year round on an as needed basis.

⚠️DO NOT put these into the ground. Grow in containers so you can control them. They spread fast, if put into ground.

[Thread] So, let's talk about #Knotweed! Yeah, it's extremely invasive and hard to get rid of. And you DON'T want it anywhere near your buildings, especially basements (and yes, my grandparent's backyard was overtaken by it -- luckily, it preferred the backyard being near a marshy area). I spent a lot of time as a child practicing swordfighting with a wooden sword, and cutting down the knotweed. I sometimes wondered if it was edible as well (since it reminded me of rhubarb -- and yes, it is edible). And of course, the BEES love it. But still...

Anyhow, let's examine natural solutions to getting rid of knotweed, and if it's somewhat contained and not a threat to structures, it can be used for food and building materials...

I grow #ThaiMint & #VietnameseCoriander out of one of two repurposed bathtubs that I use for #gardening purposes.
Vietnamese coriander isn't a true coriander. It's actually an #edible #knotweed. Never put these into the ground if you don't want it to spread. I grow all of ours in containers. I have 2 large grow bags with lots of them growing. I grow lots of both of these plants because we use them in/with our Asian foods often.

I recently found out I have a small infestation of European Knotweed in a corner of my yard, and this is Bad. Sounds like somewhere between having Tribbles and Triffids. Fortunately, the country has an eradication program to protect watersheds, and I qualify for a free cleanup, but I forgot to send in the permission form for them to come on my land. Had to run it to the county seat today. Also, getting rid of this may take THREE YEARS!

Japanese knotweed (𝘙𝘦𝘺𝘯𝘰𝘶𝘵𝘳𝘪𝘢 𝘫𝘢𝘱𝘰𝘯𝘪𝘤𝘢), from August of 2018:

#BloomScrolling #wildflowers #polygonaceae #knotweed

So, if flooring products and furniture can be made from #Bamboo, it can be made from #Knotweed. TBH, the best way to deal with an invasive species is to find a use for it (and/or eat it into near extinction -- humans are good at that...)

Japanese knotweed's potential for #furniture

"For designer Samy Rio, a cabinetmaker by training, a change of perspective is needed when it comes to how Invasive Alien Species are dealt with: 'Current destruction policies of IAS—be they floating primrose willow, bamboo, baccharis or Pampas grass—are not a solution. These invasives should be considered as potential sources of raw materials—a resource to be valorized, in particular to create new materials with added sustainable value'.

"The Gardon table—thus named for the river in the south of France where the plants were harvested—features a top made from Japanese knotweed honeycomb and legs from solid Robinia laminate assembled with pre-vulcanized latex glue. Or the 3KG bench: a two-meter bench that weighs three kilos made from panels of Japanese knotweed sandwiched between 3 plies of black locust veneer."

Fucking Japanese Knotweed is STILL coming up. 🤬

Looks like we could nuke this from orbit and it still wouldn’t give a ha’penny jizz. 🖕🏻

@hugo For the #knotweed: combination mechanical and chemical. I don't like using herbicide if at all avoidable and don't use it anywhere else, but just trying pure mechanical control with the knotweed is basically pointless. And just letting the knotweed run wild would let it absolutely dominate over native species and risk messing up some stream banks and riparian.

This is our second year here. The first spring and summer I was unaware of it until it had already sprung up a lot, like 2-3+ metre stalks in very dense stands. I cut them to near the ground with shears, then sprayed glyphosate (RoundUp) into the cut stalks. I pulled some of the bulbs or stalks, which often snapped the roots. Honestly I didn't yet know what I was in for. They grew back with a vengeance, and I did another round of that last year. Each time I probably cut down about a ton or more of stalks. We kept the stalks piled on tarps to dry out, then burned the dried out stalks.

This year I'm more methodical. I've caught them earlier and know where the stands are. In doing lots of research and reading, from invasive species management folks that have specialized in knotweed for decades, to local guidance from BC Invasives (https://bcinvasives.ca/), to reading up a chunk of long term studies and academic papers and reports, the key issue with them is their ability to pull sugars and nutrients into the rhizome to defeat a lot of control efforts.

So, the process I have at the moment is:
Don't let the stalks get too high; maybe 1-3', though some may sneak by and grow larger. Cut them such that there are at least a couple of good, broad leaves left. Often there are shoots that spring out from the "knuckle" where the main broad leaves are on the stalk; do cut those as well so you don't have any shoots left that haven't been "topped". Generously surface apply glyphosate to the remaining leaves, coat the whole stalk down to the ground, and also spray into the open segment where it's been cut.

For smaller ones that haven't yet developed hollow segments, it may be fine to just coat the whole thing + leaves, but often I'll still top them with the shears so they don't have an "uninterrupted" growth path.

They sometimes do have a different growth pattern where they don't have a thin stalk that shoots leaves early, but a softer main stalk with just tiny sprouts of leaves on them, with the whole thing more reddy pink; it looks almost like asparagus. Just coat that whole thing with glyphosate, and possibly top them with the shears as well.

So far this appears to be working really well. There are still lots of shoots in at least the one area that has heavy sun, but they've not managed to just absolutely dominate like they did last year. The sprayed and cut stalks eventually wilt at the tip, the leaves die out, and it goes brown or black at the tip and shrivels up. The stalk dies out and doesn't gain further growth, and the main rhizome cluster has to try to send more shoots up. Where the other stand is, we have a chunk of nettle that is starting to encroach on that space, which should hopefully manage to crowd out the knotweed if we keep it under control. We may try to get some Saskatoon berries into that one sunny patch, and to try to entice the existing salmonberry bushes near the shady areas to expand over a bit.

I'm tracking having to repeat this every few weeks to keep things under control. Overall, the objective is:

• Don't let the stalks run wild and get heavy growth; you don't want lush leaves that can feed the rhizome.
• Do cut the stalks, but not to the ground. Leave some leaves on them that get coated with glyphosate and can pull that down into the rhizome.
• Do not try to just pull them out; you'll just disturb the rhizome and it'll get more aggressive, but now you didn't make it waste energy on stalks that will ultimately die out, and you lost the opportunity for those stalks to pull the glyphosate down to weaken it. To be brutal: injur the enemies' soldiers, don't kill them.
• Don't just leave the stand's area open; try to encourage native species to grow into the gap.

And this will probably take multiple rounds per year over multiple years to get under decent control. But, it appears that the key is not to just try to chop it down aggressively, but actually let it use up some energy sending up shoots, don't let them get too developed, and then use them against the rhizome to deliver the herbicide to it. Weaken and starve it over years.

Happy to report that the second round of #knotweed battles this season is showing promise. While we do still have lots of shoots popping up, the first round of spraying appears to have done a decent job containing the ones that were present in that round. Second round is focused on some cutting back of ones that are getting out of hand. But, adjusting the method somewhat based on the results of the first round. Previously I'd cut them down near the second "segment" in the stem and spray into the stalk. Since leaf + stem treatment appears to be somewhat successful, adjusting that now to cutting things down to leave at least a couple of leaves, but still topping them to cut back the worst of it. Then, surface application on the remaining leaves + stem. Catching them earlier this year, and hoping to stay on top of it so hopefully we don't have a repeat of last year of having to cut back massive stands of literal tons of 2-3m stalks.

I've ranted about #knotweed before. This gives, I think, some impression of how absolutely dominant and relentless it can be.

So yeah... #Japanese #Knotweed.
(Very) long read that, I thought, might share new insights to finally be able to destroy this 'pest' (it does knot).

The #invasive #species has been calculated to cost more than £165 million to manage every year in the UK alone. Its presence can blight property purchases for households across the country.

@WeShall wow. Our neighbor's, after a patient five-years of covering them over finally were rid of theirs. Five years under cover and whenever you peeked under - there were their little white shoots ready to zoom. #invasiveplants #knotweed
