Basically the title. TOH suckers have popped up inside and around just about every single plant and shrub in my garden. I did a brush of diluted triclopyr on their leaves, but wanted to see if there's any other method I can try if this round doesn't see results in a week. I was thinking of getting syringes and injecting the stem of each sucker with 1ml of concentrated triclopyr next. Thoughts? Ideas? Trying to avoid spraying because they are quite literally growing inside my evergreen shrubs.

Hello! My parents have a 12 foot tall toh tree. I was planning on hacking and squirting in the fall. My main issue is it is covered in spotted lanternflies right now, and I mean covered. They are very large and very scary and I can only spray the ones I can reach with dish soap and water and WD-40. They also fly at me and Im traumatized by it. How do I deal with them without burning the tree down and endangering my parents property? I’m currently resting inside after being bombarded by them flying at me after a long wet dish soap dollar store spray bottle frenzy. Did I mention the very big bugs flew at me? I’m a grown man with back issues and I screamed in a pitch I didn’t know I was capable of.

I have a tree of heaven in the back of my property I'm planning to use hack and squirt on. My neighbor also has one on his property. I plan to talk to him before I do it, but I'm just trying to plan the conversation... If I poison mine will his die off also? Approximately 30 feet away. He has several in that area.

I'm sure someone will mention it but I'm planning to offer to share the poison with him if he wants to take his out too.

I have a few little ones in my yard (tallest is about three feet) and I know it’s time but it’s supposed to rain all week. Tomorrow looks clear but the next two days rain is predicted. Should I go ahead anyway?

Hi guys,

I am in Germany and not allowed to use herbicide on them - is there any other way or am I screwed?

I have 3 trees of heaven (around 2-2.5 meters or 6-8 feet tall) but I am legally not allowed to purchase or use herbicide. I wrote to the government office in charge of this, and all they said was:

"The tree of heaven can only be dug out with the root system. Saw off the tree crown and remove the root system using a pickaxe and spade ".

But won't this make them send out more babies ? Would it be better to girdle partly without chemicals to weaken it a bit first, and then try the root system? Or would that also wake up its defenses?

Any tips on how to attack this would be so helpful. Thank you!

My neighbor has two tree of heaven saplings and they are attracting lanternflies that come and eat our willow. I want to remove these saplings to protect our willow but directly handling the trees ourselves is not an option. I read that you can drill holes in the trunk and pour herbicide in them. We are close enough where we would be able to do this on our property.

Hypothetically - would it be wise to do that if I then cannot remove the tree itself? Would it be better to leave the saplings alone so they do not create more saplings, or should we go ahead with pouring poison in the trunk?

My arborist and I did the stump and drill method on three trees in June. Tree 1 has not had any new sprouts. It's dead.

But last week, I noticed Tree 2 of was sending out root shoots and Tree 3 was sprouting from the leftover stump and sending out shoots. I have been spraying all 3 regularly with highly concentrated triclopyr and have highly concentrated glyphosphate on hand. Recommendations? Should I hack and squirt? Strip the bark?

Same old story: just getting educated the hard way. Here is my gear. I realize I doubled up on the triclopyr. One is for the sprayer (pathfinder); the other is for the hack and squirt. NGL: I'm nervous about carrying the chemicals on my back. I'm not too sure about needing the surfactant but I added it just in case because I'd rather have it and not need it. If I'm able, I'll post a picture of me prior to heading out. I'm aiming for only one spray this year and will spot treat as necessary. UGH!

UPDATE: well, just found out that our electric company is putting up a pole in the same place as one of the trees of heaven :/ I’m not able to get the triclopyr until Wednesday and they are doing the work on Thursday. I was able to talk to the forestry/arborist they had with them and asked them to treat it and they said they would treat the stump. 🤔Hopefully they at least do that. It’ll still send off suckers in about 2-3 weeks. Double UGH!

Hey everyone!
Denver ToH killer here, wondering what y’all’s thoughts are on in terms of the window. From what I see, it’s recommended to apply those herbicides in late summer/early fall when these guys start sucking down to the root. Are we there yet? Should I wait a few more weeks to allow some sucker growth so that I’ve got some prime targets for foliage treatments with my bioadvance brush killer? I’d love to hear where others’ minds are at!

Edit: Well, I just treated everything in the yard! Nothing above 1 ft, but lots and lots of sprouts. Thinking previous owners had some trees and cut them/buried them in the winter then sold us the house, and neighboring yards have some large trees. So, everything was sprayed with triplocyr and marked with a flag. Let’s see how it goes!

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!

Zone 6b central Illinois, I’m getting antsy but August is listed as the start of energy being sent to the roots.

Good to go now or am I better off waiting until later August/early September?

I have this herbicide already. As per directions on the bottle, will it work on my tree of heaven suckers?
