Hypothetically speaking, let's pretend my neighbor has a huge honey locust right next to my fence and garden, sucking water from and shading my garden, and dropping pods in my garden so I have little locust trees coming up as weeds in my garden.
If that were to happen, what would be the best way for that tree to accidentally die?

cut the branches that hang over fence this is legal in Michigan

Honey locusts are not very desirable in a yard. They have terrible thorns and give very little shade. The best way would be for your neighbor to cut it down or for you to help the neighbor cut it down.

they make good firewood. offer to cut it up for him. after the stump is two or three years old and you routinely cut anything that grows up out of it, cut as level with the ground as you can. bury it in charcoal and light it. will burn several days but stump and all will be gone. fill the hole with a few bucket fulls of dirt

Take a cordless drill with a 1/2 bit, drill down at an angle 4/5 inches, fill with Roundup,use sawdust to plug hole. Never tried it but heard it works great

Tordon RTU works awesome too!

copper sulphate

How about approaching the neighbor and explaining the problem and offer removal of tree and planting a new better variety that will benefit both of you.

Just poor a lot of roundup at the base of the tree. it will kill it, diesel fuel would probably do the same.

Tordon is how we kill out Honey Locust trees in the pasture, but keep in mind that Tordon does translocate through the roots into the soil so more than likely you will have negative effects on other desirable vegetation including your garden.

I would explain the situation to the neighbor and offer to help cut it up, if that doesnt work explain that you are going to remove anything hanging on your side of the property line.

If you vandalize the neighbor's tree expect karma to have dead tree parts falling on your property for a long time. Talk to the neighbor.

Here is a link to a recent thread on a similar subject- How to kill a Bradford pear Scroll to top of page.

Spike80 one hand full will do the trick

Talk to the Neighbor ...or move the garden.

A few copper nails will do the job.

Hypothetically speaking, one large beaver or two. And when the job is finished, offer to trap the "nuisance" beavers at a discounted rate.

Talk with your hypothetical neighbor.... If that fails, then unleash the beavers.

OK everyone keeps saying use copper nails. Next question WHERE do you buy copper nails ???????

Whatever happened to just talking with the neighbor about it.
