#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."

Eating #JapaneseKnotweed: Safety, Recipes & ID Guide

2025-08-17

The Basics: Eating Japanese Knotweed Safely

"Before you grab your harvesting basket, let’s cover the foundational knowledge. Getting these basics right is the key to a safe and tasty foraging experience. It’s all about what you eat, what it tastes like, and most importantly, when you eat it.
What parts of Japanese knotweed are edible?

"The only parts you should eat are the new, young shoots that appear in the spring. You’re looking for stems that are tender enough to be snapped easily with your fingers, much like fresh asparagus. These shoots should ideally be between 6 to 12 inches (15-30 cm) tall.

"As the plant matures, the stems become tough, woody, and fibrous, making them unpalatable. The leaves and flowers are not typically consumed. Always peel the outer skin of the shoots, as it can be a bit tough, and only use the inner core. The inside is hollow, which is a key identifying feature.

What does Japanese knotweed taste like?

"The flavor profile of young Japanese knotweed is one of its most pleasant surprises. It has a distinctively tart, tangy, and refreshing taste that is remarkably similar to rhubarb, but perhaps a bit more 'green' or 'lemony.' Some people also detect earthy notes, similar to asparagus or sorrel.

"Because of this similarity, it’s an excellent substitute for rhubarb in most recipes. It cooks down into a soft, pulpy texture, perfect for both sweet and savory dishes. I once made a knotweed and strawberry crumble for friends who were skeptical, and they couldn’t tell the difference from a classic rhubarb version!

When is the best time to harvest Japanese knotweed?

"Timing is everything. The harvesting window for edible Japanese knotweed is quite short, typically lasting from mid-April to late May in most North American and European climates. The key is to catch the shoots when they are young and tender.

"Here’s what to look for:

Height: Aim for shoots under 1 foot (30 cm) tall.
Texture: They should be crisp and snap easily. If you have to saw at it with a knife, it’s too old and will be unpleasantly woody.
Appearance: The young shoots are often reddish-purple and speckled, resembling asparagus spears.

"Once the plant grows taller and its distinctive heart-shaped leaves begin to unfurl, the stalks quickly become tough and fibrous. Harvesting too late will result in a stringy, unpleasant meal."

#JapaneseKnotweed: an invasive plant's potential for innovation

Classified as an Invasive Alien Species (#IAS), Japanese knotweed is renowned for undermining ecosystems. But some researchers, designers and architects are approaching the tenacious Asian perennial as a resource to create new material solutions for fine crafts, but also for industry. Formes de Luxe shines a light on four makers that are turning this ‘nuisance’ plant into an opportunity.

In the UK, architect Irene Roca Moracia and designer Brigitte Kock (both graduates of Central Saint Martins) have also seized on the potential of invasive knotweed to create what they dub 'bio-concrete'. The material, developed as part of the LVMH Group's Maison/0 program for regenerative luxury, is inspired by the cement made in ancient Rome. Except that in this case, knotweed replaces wood ash and/or volcanic ash. Once incinerated, it is mixed with water and the shells of American signal crayfish - another invasive species in Europe threatening native fauna. The material is then poured into molds to obtain the desired shape.

"No heat treatment is needed as hardening takes place in the open air and no pigments are added either: the final textures and shades depend on factors including the proportions of ingredients in the mix, hardening times and reactions that occur between the water, aggregates (crayfish shells) and the Japanese knotweed binder. With the appearance of raw concrete, marble or natural stone, the duo's hand-shaped bio-concrete tiles come in a range of shades from white to wine-red, with or without inclusions of knotweed root fragments.

"For the moment the material is purely decorative as it cannot integrate structural architectural elements but is suited to store interiors, window displays or even in caps and ornamental pieces for packaging."

Senior Science Project: Convenient, Eco-friendly Chemical Treatments For #FallopiaJaponica (#JapaneseKnotweed)

"Problem: Japanese Knotweed is a highly invasive species, which threatens to out compete many native plant species in the eco-systems of North America. Invasive infestations such as that of Japanese Knotweed are extremely disruptive to the natural rhythms of both flora and fauna of a given habitat. This is why controlling Japanese Knotweed has been made a priority by most conservation efforts in areas where it is present.

Thus far herbicides have proven to be the only effective treatment for killing this plant and ensuring that it does not come back to re-inhabit the same given location. Due to the extensive root system, which if left even partly intact will cause the plant to re-sprout with greater vigor. Cutting, burning, and even manual extraction of each individual plant often prove to be ineffective. The herbicides used in treating Knotweed are not unlike household weed killers such as #Roundup®. These herbicides are designed to have minimal environmental impact but still are discouraged by environmentalists due to potential for soil and water table contamination. The goal of this experiment is to find a cheap, accessible, and environmentally friendly alternative to the herbicides on the market.

Control Treatments:

- Water
- Roundup

Experimental Treatments:

- Isopropyl (rubbing) Alcohol

Known to kill foliage by dehydration. This puts stress on the plant as a whole.

- Glucose syrup

Glucose is the product of photosynthesis and a plants primary source of life energy. In animals the introduction of unnatural levels of many hormones and chemicals (including sugars) can disrupt the organisms ability to produce these crucial chemicals naturally. The introduction of high levels of foreign glucose may disrupt the plants ability to produce glucose naturally.

- Brewed Coffee

Coffee contains a multitude of stimulants and other chemicals. One of these compounds is dimethyl-xanthine, which has been shown to inhibit the production of cytokinin, which is crucial to root growth and cell development. This chemical may attack the roots as well as the foliage.

- Magnesium Sulfate (Epsom salts) dissolved in water

This salt very hydrophilic and likely to absorb water from foliage and stem. May hinder transferal of water from roots to foliage.

- Phytophthora Cinnamomi

This is a common fungus also known as “root rot”. It decays roots that are in wet or saturated soil causing plants roots o rot thus killing the entire plant. This fungus is aggressive and seen as a worldwide threat to plant life. If injected into knotweed stems this fungus may selectively kill the target plant with out threatening neighboring plants.

- Vinegar

Vinegar is acidic and will kill foliage and stalks. Apart from stressing the plant above ground the low ph may also kill roots if absorbed from soil.

Conclusion: "The commercial treatment for Japanese Knotweed (Roundup) did not kill its host plant. Vinegar and coffee proved to be far more effective then the herbicide option in killing this weed. The vinegar’s acidity appeared to overwhelm the plant so quickly that the roots system may also have been stressed. It appears likely that the coffee did what was predicted. It attacked the root system causing the entire plant to die.

It was surprising to find the specimen treated with Roundup to still be alive after nine days. Its growth was clearly inhibited and its foliage did show signs of stress. This plant may be hearty enough to resist the herbicide. The abrasive properties of the alcohol likely caused the damage to the foliage thus stressing the plant enough to prevent further growth."

[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...

Japanese knotweed (Reynoutria japonica) in a field of lesser celandine (Ficaria verna). I'm in Pennsylvania where they were originally introduced in 1800s, both as ornamentals. The Japanese knotweed was also planted for erosion control. Now horribly invasive but at least the bees like them. #JapaneseKnotweed #LesserCelandine #InvasiveSpecies #weeds #plants #ecology #pennsylvania #pollinators #polygonaceae #ranunculaceae

Why is #JapaneseKnotweed (Reynoutria japonica) so highly invasive?

By comparing growth and reproduction traits of introduced plants with native plants, investigators discovered that introduced plants had gained the ability to reproduce faster by clonal propagation, a method of asexual reproduction that creates genetically identical copies of a plant.

It is estimated that there could be a Japanese knot-weed infestation every 10 square metres in the UK.

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...)

#JapaneseKnotweed: an invasive plant's potential for innovation

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. 🖕🏻

@soniashah @NatGeo The more I hear about feral pigs or hogs, the more I like it as a solution to many #NYC problems. There are no crops in #NYC to eat outside of gated gardens. They will be a problem for motorists. Will they be a problem for bicyclists? Their presence will encourage all bikers to go slow. They will eat non-native invasives such as #japaneseKnotWeed, #ItalianArum and #LesserCelandine as they root around.

Could the answer to every #gardeners problem - #Japaneseknotweed - be to eat it... Douglas McMaster of the Hackney Wick restaurant tells us that 'Japanese knotweed is incredible, its like a mix of asparagus & rhubarb'.

Time to allow the harvesting of invasive species, and encourage its inclusion in a balanced diet?

Good,bad and downright #weird stuff on my walk through the #nature reserve today.
Great skies and then #japaneseknotweed and the comfiest seat you'll see in 2 of the most #inaccessibleareas .
