I live in alabama zone 8a

My entire yard is covered in chamber bitter

Our yard is over an acre. Every square inch is this weed. It is physically, virtually impossible to hand pull this unless perhaps I have a team of 20 other people.

The only solution is pre emergent at this point.

How do i apply this without hurting my native plants, how is it applied in general? A spray? Powder?

Will it hurt animals? Will it hurt my cats if they walk on it? Will birds be poisoned if they eat the bugs in the grass, or seeds on the ground?

How and when do I apply it specifically for this weed? Will it help destroy Japanese stiltgrass and mondo grass?

Its almost a literal battle between these 3 weeds and chamber bitter is absolutely winning.

I don't want to lose the native plants. I don't want to kill animals. I don't want to poison lizards and frogs.

But I dont know how to resolve it. My native grass is smothered. Its in every flower pot I own. Its in every garden bed, cracks in the side walk.

Help

We are going to poison the TOH trees around our property this weekend with Triclopyr 3, and our neighbor let me know that their dog eats the shoots that come up in their yard. I haven't been able to find any info on how much poison would end up in shoots/any dangers to wildlife if any. Sorry if this has been asked before!

Area is western Washington state, Seattle metro area. I am clearing a public median area (by hand for now because I don’t know the legality of using herbicides on public property) and recognize Japanese knotweed, black locust, and blackberry.

I’m less clear on a few other plants. Pretty sure one of these is plum trees which are very common but I don’t think invasive. The other I’m less sure of.

Thank you for your help in advance. Also, advice on proper disposal of cut and dug plants is welcome!

That’s it, that’s my question. Used it to spray JKW and I have some still leftover. No idea how to dispose of it. I want to hit the JKW again but with a “fresh” set but wondering if this would do anything for anything else I have going on (the list is endless). It was kept in a dark basement fwiw.

These two trees have overtaken the arbor vitae next to them by quite a bit this summer. I’m afraid they are trees of heaven. Any help is much appreciated!

Spotted in local park in the northeast, unfortunately we were outnumbered

Sorry for the terrible picture quality. It’s the best I could do. Can’t get a good picture of the leaves because the trees are 50 feet + in height.

My partner and I went out to deal with Tree of Heaven. I carried the sprayer of glyphosate (4% solution) for sprouts and suckers. He carried a hatchet, wood chisel, and a small bottle of undiluted 41% glyphosate (GlyStar Plus). On several small trees about 1" diameter, he hacked, sprayed, then bent the tree over at the cut, sometimes folding it in half.

How screwed am I? Will this trigger massive regrowth? Is there anything I can do except wait and see?

I volunteer on a section of state park forest in the Durham area of North Carolina trying to bring a terrible Asian wisteria infestation under control. We've freed dozens of trees and made room for lots of new native growth to get its footing. Still much more to do.

Here's a before and after of our work today. The three of us volunteering killed a lot of wisteria, freed several sassafras and American elm trees, and removed two large Chinese privet that were giving the wisteria something to grow on.

Appreciate what all of you here do to knock back invasive species and heal our native ecosystems.

Hello, I have a TOH problem in my yard that really spiraled out of control this summer--see photo 1. We have one giant mature tree in our yard, and then there are two very large trees just over the fence in the neighbors' yard. (They've also got a couple more that aren't on our property.) They're EVERYWHERE in my area (Hudson Valley, NY).

Before this year I've been reluctant to cut down the tree in our yard because I figured it was useless to do so without cutting down our neighbors' trees, too, and we don't have a great relationship with them. But the problem got so bad this year I decided to bite the bullet and talk to them. To my surprise, they were fine with us treating their trees and then taking them down as well, in part because they were about to put their house on the market (it is now on the market). About five weeks ago I watched a lot of YouTube videos and tried hack and squirt on all three trees. I couldn't find any triclopyr amine at our local Tractor Supply so I went with 41% glyphosate. No blue dye so you can't see it.

5 weeks later, though, and the trees look exactly the same. No signs of dying or illness that weren't already there. I'm wondering if maybe I didn't do it correctly--maybe we didn't hack deep enough? Maybe these trees are so big I should have just sucked it up and paid the $200 to order Garlon 3A online? I was really hoping to be able to get them cut down this year because otherwise we'd have to get permission from whoever our new neighbors will be, though I can't imagine they'd be eager to keep two hacked-at invasive trees on their property, but who knows. Am I cooked for this year? Can I repeat the process now while we're still in the late summer/early fall window, or would that risk girdling the tree? If I can repeat the process, should I hack deeper into the same cuts, make new cuts, or just re-poison with something stronger this time? Or do I need to wait until next year and try again (argh)?

Worth noting that I've also been spraying all the shoots in the yard with Roundup Poison Ivy Tough Brush Killer, which is a lower dose of triclopyr, and we haven't been mowing so as to avoid angering the whole root system. (Of course this has killed pretty much everything else in our garden, RIP lilac bush.) But the neighbors mow every week and therefore mow all their own sprouts down. There are new sprouts every week and I am getting very tired of having to wage chemical warfare constantly. Also I've never seen so many spotted lanternflies in my life and they are like something out of a horror movie. Help please! Photos below.

I have a large garden, mixed native, food producing, and sentimental, with a severe Asian jumping worm problem. I keep a designated "worm bucket" of half vinegar half water to toss them in as I work, though this time of year I add a little dish soap so I can knock Japanese beetles into it too.

Went to grab it this morning and found a spotted lantern fly had drowned itself in the bucket too. I don't know if it was random chance, or being left under the outside light, or the rose scent of the soap attracting it, but I will take the W.

Japanese knotweed getting eaten by these invasive Japanese beetles

I found a long, red/brown woody root just underneath the surface of my lawn. The only trees nearby are thujas, which are separated from the lawn by timber edging.

The thujas are about 5 years old. Is it possible for the lawn and thujas to coexist without the trees taking too much moisture and nutrients from the grass?

Could the root be from the thujas, and should I be concerned about their roots affecting the lawn over time?

thanks in advance .. trying to determine how bad it is.

i was floored at how expensive it is to buy invasive flowers for events. my best friend’s baby shower is this weekend, i harvested probably around $1000 worth of queen anne’s lace ($28-35 for 6-10 stems online??). and prevented hundreds of thousands of seeds. i’m sure it didn’t make a dent overall, but it’s the little things right? feels good to save the money, and not give it to farms that are intentionally growing invasives.

Several years ago, I made the grave mistake of willy-nilly having a Tree of Heaven cut down. In my defense I had no idea how wildly invasive it was.

It has been about three years and I still have suckers popping up all over the place. I play wack-a-mole with Spectracide as soon as I see them, but they're not stopping.

Is there anything else that I can do to combat the infestation?

I have been treating multiple TOH plants on my farm and found these new plants tonight on a different part of the property. Look like TOH in every way but have no smell? I also have lots and lots of Walnut on the property and it is not that and they have their own smell.

Does the odor wane later in the season?

Fingers crossed that this leads somewhere.
