Will Roundup Kill A Tree?

Will Roundup Kill Trees? Undiluted Roundup can kill trees, however, when I used it on my Chinese Elms it didn’t work.

I haven’t tested Roundup on every tree type so it may work on yours. Some trees are more resilient than others.

Let me know if it works on your tree in the comments at the bottom.

In my research, I did find a way that Roundup will kill even the hardiest trees, every time.

How To Kill A Tree With Roundup

For Roundup to kill even the most resilient trees you need to mix additional chemicals. Here’s the roundup tree killing chemical recipe.

Each of these ingredients needs to be used in their concentrated forms. Add and mix them into a small container like a glass jar.

Mix these ingredients and apply with a paintbrush to the cambium layer, just inside the bark. Treat immediately upon cutting the tree down.

Waiting even 30 minutes will lessen this mixtures effectiveness.

You don’t need to paint the whole stump only the outer cambium ring.

Making this recipe costs more than Tordon and takes more time. So unless you already have these chemicals on hand it makes more sense to use Tordon.
