Hi folks, I'm just a civilian with a backyard here, learned that these things that are/were everywhere are tree of heaven, and I discovered this big one growing into the walnut trunk (pictured); what would one ideally do with this situation?
Thanks!

I would just cut the sucker back. Poison will absolutely hurt everything around where you apply poison. It might take a year or two, but cutting back the smaller trunk will eventually kill it.
Make cuts in the trunk of the TOH and apply glyphosate herbicide to those cuts. This will allow the tree to uptake the herbicide without promoting the growth of suckers which is what happens if you cut it down.
This will not hurt the walnut.
What’s “TOH”?
Im not seeing a walnut tree pictured. Are you thinking the bigger trees in your pictures is a walnut and the smaller ones at the base are tree of heaven? If so that isnt right those are all one tree of heaven with the smaller ones being suckers shooting up from the base
Are you sure the “walnut” isnt actually tree of heaven as well?
Pull leaves off both trees and smell the leaves.
Tree of Heaven leaves smell absolutely vile. (I know because my neighbor has one, and I have to pull up seedlings all over my yard)
If the leaves smell the same, they are the same type of tree.
Copper nails?
RIP fence
Hate to say that the whole thing is a TOH. there’s not a walnut here.
The larger tree looks like tree of heaven too based on the bark. Could you post a picture of the leaves? If that was a black walnut you’d have hundreds of black walnuts falling in your yard every year because that tree is certainly old enough to produce. Do you get a bunch of walnuts in your yard?
Walnut has serrated leaves and does not have a terminal leaflet.
Sumac has serrated leaves and has a terminal leaflet.
TOH has smooth leaves with divots and has a terminal leaflet.
You can basil bark to paint the bottom of the trunk and then it will permeate the bark to pull the herbicide into the roots.
To kill the bigger tree, you’d need the hack and squirt, hire arborist to cut it down 30 days later and then immediately — like within minutes, herbicide the stump.
Go to Penn State Extension for the type of herbicide for each size of TOH.
It’s easy to tell them apart. Break off some leaves. If they smell sweet and aromatic, it’s a walnut. If they smell like rancid Chinese peanut butter, then it’s a TOH.
Both are two close to the fence. You is hard to kill but small enough for you to remove with a saw.
Instead of using herbicides, cut an incision all around the bark so that you cut the cambium, possibly during a hot day. It should slow it down without letting it sprout again.
OP, your walnut is not producing walnuts because it’s not a walnut. TOH all around. Go scorched earth
TOH, all of it
You think multiple species of tree are coming from the same trunk…?
Kill it all
Takeoff and nuke the entire site from orbit. It’s the only way to be sure.
All TOH.
All of them need to be removed. Then continually removed over the next year or two.
One starts taking an inch. Then spreads to try to cover a mile.
Very little grows near a Black Walnut. Is the ToH different? Just wondering.
