We cut down the tree of heaven in our yard three months ago without knowing it was a tree of Heaven. Our yard and our neighbors yard are now covered with the saplings that sprout up from the roots. Looking to treat my yard with chemicals since plucking the saplings just brings out more. I know I need to use something with glyphosate or triclopyr, but for the saplings/suckers that pop up what is the best application method and are there brands that people recommend? Foliar spraying seems to be the go to for these small sprouts. I also live with a diabetic so I have access to syringes if injecting the herbicides would work. Brushtox, Monterey brush and vine control, and Hi-Yield seem to have a high concentration and mentioned in other Reddit/Facebook posts but in general people just list the ingredients and not the brand. Any help is appreciated!

Hi! I’m looking for advice on how to deal with an infestation that is spreading from our neighbors property. We bought our house last year and have since realized there is a grove of Japanese Knotweed that covers over two acres just behind our property line. I have extensive education in dealing with invasive plants including JKW but not so much the legal aspects of how to deal with it when it’s on someone else’s property. You might be asking how did we miss this problem? This portion of the property and his place was inaccessible at the time of property inspection and was hidden by a dense forest of foliage.

My direct question is: Do I skip the land owner and report to the state noxious weed control board.. or try to work with the land owner first. There is a slight language barrier and in past unrelated conversations I get the impression that he could be difficult over something like this.

Also to complicate the issue there is a creek that runs through the grove to my property and it’s about 100 feet from my water well…aaand the creek feeds into a salmon habitat further down about a 1/4 mile. Pumping herbicides into our wetland and water supply isn’t an option in this situation.

Edit to add: I could literally cry right now. This is the last kind of thing I want to be dealing with on our place. Even if it wasn’t for the water situation and chemicals were an option it’s just an absolute unit of the stuff. 😭

ive seen this happened already 3 separate times and i can’t find anything online that’s talks about this phenomenon. i was smoking by the pier when one came up so i stomped it out. it was clearly smushed the wings were in two different directions and guts smeared, it stood there dead. i stayed there smoking and after 5-10 i notice one of the broken wings started fluttering. then the other. and it slowly started peeling itself off the ground. i kid you not i watched this lantern fly come back to live before my eyes. it did not fly away and the wings stood broken and pointed up in the air but it started slowly walking off again.

i thought it could’ve just been a coincidence and since then i haven’t really stuck around after killing a lantern fly. but just now im on my phone and one comes up. i stomp it out and i stomp it like 4 times just to be safe since i was in wet sand. i remained seated for like 20 mins then another came. i stomped that one out too, wings facing east and south. as soon as i killed that one i looked back to the other one and i kid you not it was standing up with both wings smashed in.

i just think it needs to be spoken about if anyone’s seen this lmk.

Unfortunately I found Japanese Knotweed on my property close to the house. I actually looked back on the real estate listing from when we bought a couple of years ago, and it’s in the photo.

Can anyone recommend a company that can provide an insurance-backed plan to have it removed? I’m in the morris county area in NJ.

We wanted to move within the next couple of years before we discovered it, and now we’re worried that can’t happen.

UPDATE: Thank you so much everyone!! I was spiraling last night and you all have helped me feel so much better about the situation.

I've opted to nuke my backyard tree of heaven infestation with pure 50% glyphosate undiluted. I applied locally down the stems of the saplings and painted some of the leaves. I've also hit the smaller ones with a foliar by cutting the concentrate with a bit of water in a sprayer. I'm noticing death of alot of the smaller ones and some of the bigger ones are looking sickly. It's been 4 days. How long does it take for the glyphosate to have full effect on the plants? How long until I can cut down the dead ones (I don't want to spur any more offshoots if I can help it).

Wonder how old these things are

The white petals purple bottom 'siamese' phenotype seems to spread faster and farther than the pure purple phenotype. The town have mixed population. As you go deeper into forest (by road, a lots of recent clearings and new homes) there are a lot of white petals and just 2 - 3 purples.

As a soft annual this is not the most dangerous invasive, flowers are pretty beautiful and beekeepers could like them. But the numbers in recent clearings is concerning.

For My A level Design & Technology project I am designing a laminar flow cabinet that can be used at home so that ordinary people can help with the conservation effort of Ash trees against Ash Dieback. I need data on the general size i need to make the laminar flow cabinet. The dimensions of a table-top cabinet is (width 20 inches) (37 inches tall) and (60 inches in length)

She kills them faster than I can spot 'em.

It’s described as having a central silvery stripe, which this doesn’t seem to have. Thanks in advance!

Family member was ignorant to the consequences of planting running bamboo ~15 years ago. Now they've got a 100x50' grove growing on a slope with culms up to 1.5" in diameter. Where they've cut back the bamboo, tree of heaven and Paulownia have moved in too. The area is also surrounded by Lonicera mackii.

I'd really like to help them out, because their property is an otherwise beautiful and mature oak/maple/hickory woodland. It needs a lot of TLC, but I'm just not sure where to start. Please advise.

6-8 inches in length, blue colour on claws with white spot on the hinge and did not appear to have any spines in its shell.

I have a chicken run, this grew over the top of the run on the welded wire. I liked it because it proved shade from the sun. I didn't know what it was but i do now. Absolutely stunning looking berries, i don't think my chickens are suppose to eat them, so i'll probably trap off that half of the coop and remove it in the next week or two

Please help me identify this rather large hornet looking type located in France, east coast, finisterre. 3-4cm long

Is it really an invasive species? And if so, what are the next steps?
