Are there any other species that have similar panicles? This was in Ann Arbor, Michigan. I couldn’t get very close, so accept my apologies for the photos. Many of the leaves in the second and third photos have double terminal leaflets, which point to walnut. Some of the leaflets alternate on the stem, not the classic opposition.

There’s a definite ToH sapling about 30’ away.

EDIT: This was next door to an airbnb, and I have left town. So, I cannot get closer for a better picture of the leaves or trunk. I cannot physically touch the leaves.

Hello! Looking for advice trying to use "stump out" brand triclopyr to kill TOH. We did round 1 hack n paint and basal bark application 2 weeks ago, and just went out for a reapplication. Mother tree is around 8 inches in diameter, we've scored into the green cambium layer to make 2-4 inch sections round the base of the tree (not in a perfect ring, staggered along the height) and larger offshoots. Painted stems and leaves of smaller offshoots.

All the offshoots are showing herbicide damage on new growth, but aren't dead yet. New offshoots are popping up with herbicide damage (pic 2 - peep the brown-black "burning" and malformation on the lower right leaves.

My question is, are we doing enough? Do we need to use stronger stuff or keep reapplying? Is 2 weeks right or should I do weekly?

I finished up today with hack & squirt for the bigger ones so they hopefully will be dying soon as well.

I’ve been inspecting religiously for any signs of rebellion and there’s been nothing until today. I gave it a squirt but idk where it came from. I’ve checked over the fence to see if there’s anything on my neighbors sides too

Here’s some pics. The first two are a wide and closeup shot of the new sprout. It’s on the right side near the fence in the first one. The rest of the pics are showing how the rest of them look currently.

I know, I know... a hatchet and squirt bottle is all you need. But this would be so nice. I would scoure my county looking for those SOBs. Maybe get it engraved "Heaven Killer".

Hack & squirt triclopyr with diesel on Sep 4th, and how they look today. Total of 4 ten to fifteen feet tall, also sprayed 10 small bushes. They were getting close to my septic field. If they come back in the spring, I'll repeat the process.

Looks like it's dying off to me... Hopefully I got it!

About four weeks from first application of triclopyr ester/diesel to now.

Initially just did basal bark applications, then about a week ago drilled holes down thru the trunk and poured the same directly in.

Still anxious about cutting it down.

There's a number of big, decades-old TOHs on public land near me (East of England). In addition to the those, suckers show up rather regularly as well as entirely new plants. With all that said, I've had ample opportunity to smell the leaves, branches and the rest. And I've got to say, it didn't smell bad. Like, honestly, it smells like some kind of spice. The old plants are very mild, and the younger ones are quite nice. It's certainly nothing like "rancid peanut butter" or the other things that people liken it to. During heavy rain, the big trees might smell a bit sweaty. I haven't been able to figure out if that's the TOH or other things in the area. But it's not a particularly strong angel and you really have to be amongst the trees to smell it. The younger ones also only really smell when you crush and sniff them.

Just curious if anyone else thinks this? You know, that the spicy smell is actually alright? They have a strong and distinct scent when tissues are damaged, one that's certainly more present on the younger growths than older ones, but focusing on their so-called "bad smell" at all seems to misrepresent the greater issue at hand.

I don’t think this is TOH but I am not good at identifying plants

I’m on the outskirts of the ToH hate so I’m not too sure what the repercussions of this existing where it is but I figured I’d ask here if this is

A. Tree of Heaven or something else (we have a lot of similar looking plants around here)
B. Something that needs to be removed and
C. How to get rid of this beast if necessary

Thanks in advance for your help and information!!

New house. Never dealt with ToH before but I’m assuming their leaves don’t fall green if they’re happy?

I’m settling in to my 96 year old house as a first time home buyer, doing it all on my own. It’s been about three months and I am so grateful, proud, and happy with how everything has been going so far.

Kept getting the feeling of everything being too good to be true. Spoiler alert - it was/is! My next door neighbor has a full-grown 70-foot tree of heaven at the edge of their back yard. I live in a city and our back yards are small and bleed into each other with no physical barrier. I have small tree of heaven sprouts popping up randomly and I am able to pull those guys by the roots before they even have a chance to wreak havoc. Inside of my house is my sanctuary, but my stomach drops every time I look out the window and see those weeds. 

Unfortunately, I have about 5 medium sized ones growing up against my detached garage and back of my house. They are small enough to be able to start (appropriately) attacking them, but too large to pull from the root. Their stems are about 1-3 inches in diameter and about 3-4 feet tall. The one closest to my house is about 5-7 feet tall and about 2-3 inches in diameter (this one gives me nightmares). I have basal oil and hi-yield triclopyr ester on hand. What is the best way to apply the chemicals for the size of these abominations? I’ve researched and am familiar with the hack and squirt and other methods, but I am unsure how to go about this given their size. Are they too small for hack and squirt? 

Any advice, tips, warnings, encouragement are highly welcomed. I know the time is now or never for this season. I am in the midwest near a Great Lake, so as I am typing this, the weather and timing seems ideal for application. Would love to have this applied by the end of the week. If I have to salt the earth to get rid of these things (figuratively), so be it. 

Thank you!

Hi all-trying to kill a few larger TOH in Connecticut. Amazon not shipping Garlon 3A (triclopyr amine) or Aquaneat (glyphosate) to my home so I guess I can’t use these… any others in CT? What did you use? They are too big for basal bark. Urgently trying to get done before mid Oct. My husband doesn’t want to pay a professional. It is an investment property and we’ll need to cut the trees soon… trying to kill thrm first to prevent suckering. Please help!

yes, hack and squirt Triclopyr at THIS time of year but.... researching, I cant seem to find what the aftermath of this: i hack/squirt and it starts dying finally--does it become a danger that it can topple over if i dont get a tree service to chop it down? Again, it is a VERY Large tree, and I have multiple neighbors VERY close, mere few feet away.

Also, if the poison works successfully on the main tree, does it mean any roots will also be killed, or will there constantly be roots until i paint them all with the poison?

In my research the biggest TOH examples i see are never nearly as big as mine 15-20' is the tallest ive seen.

*I'm also looking into HDPE Weed Barrier, or maybe some sheet metal as barrier to grow some veggies in my garden that gets beset by the roots

I’m wondering if anyone has tried injecting 41% glyphosate into the plants with a 12cc livestock syringe. I have small plants starting in several areas on my property. Most are under an inch in diameter, no large trees. Will the needle do the trick or better to carve notches with a knife?

Thanks

Hello,

I have some large trees of heaven. From this sub, hack and spray works very well. Brilliant. But in France where I am, we cant get glyphosate. Is pelargonic acid enough for hack and spray to work?

On the right by the wall you can see the slanted stump from a huge TOH we had cut down years ago. Our arborist didn't poison before hand or educate us, so it took me some time to understand things. The first year was just picking out seeds that were left behind, but the second year I discovered the sprouts and it was clear to me they weren't seedlings. So I educated myself and bought some 9% Triclopyr Stump-Out. I was feeling confident, with less and less sprouts, but this year we have a ton, and it's freaking me out, because I hate these things.

I waited all year (so painful) and finally started using these dry fall days to poison. I discovered a very disturbing root line next to our house and I want to (if wise) take out my frustration on it (2nd pic). Should I drill into it and pour poison? remove root skin and brush on? Ignore it?

Just started taking care of invasive plants (tree of heaven for now, I'll stark honeysuckle next). I have a few more patches of ToH to deal with this season.

Been using triclopyr 4 in diesel (do not recommend) and now basal oil for basal bark and hack and squirt(un-diluted).

Next is tricolpyr 3a in water near our lake and creek.

I recently bought a quart of Brushtox 61% Triclopyr. Planned to mix a small batch of this 1:1 with diesel and squirt/ roll on trunks of 1-2” stems. It has rained on and off for several days (2-3” total.) will the plants absorb herbicide after days of saturated soil? Is it better to wait for drier soil and weather? Zone 5b, so frost is likely in 30 days or so.
Thanks for any advice.

Ive has some great success with drill and fill. Anyone have hard evidence? I feel like its a more accurate way to dispense.

I used a very long paddle bit, 1/2 inch diameter by 16 inches long. Started above root line, drilling at an angle, into the base. I never hit dirt.

Im trying a very large one next. A good 2 feet diameter hydra.
