What's the best way to kill nuisance trees?

Question

I have nuisance trees that re-grow in my gardens every year. I've already tried Roundup and Ortho brush & stump killer, neither of which worked. Is there any way to kill them permantly?

Answer 1

I'm not sure how large these trees are but here's some advice to help solve your current problem;

The best product currently on the market for homeowners contains the active ingredient called; "Triclopyr". It's currently sold as "Brush-B-Gone" or "Brush-Killer" as well as other names at most hardware stores. It was developed specifically for hard-to-kill brush and trees such as what you're faced with. My personal experiences when using this product have turned out extremely well.

When using this product, I'd strongly recommend purchasing a material that's referred to as a "Spreader-Sticker"...which helps make the Triclopyr adhere to foilage or tree trunks better and allows it to move into the plant at a higher rate than using plain water (which usually drips off). IF you're unable to find the "Spreader-Sticker"... you can add a few teaspoons of dishsoap AFTER you've mixed the Triclopyr and water together....to avoid bubbles. (The soap will help destroy the waxy layer found on leaves and young tree trunks thereby allowing more product to be absorbed)

Once mixed at recommended labeled rates, you should spray the entire tree with this mixture...making sure you get complete coverage. Also, make sure you don't get any spray onto any ornamental plants nearby.

The other way to kill your trees is to use the cut-stump method. This involves cutting the tree down to expose the green tissue and immediately (within 10 minutes after cutting), applying the Triclopyr mixture (one part Triclopyr to 3 parts water) directly onto the freshly-cut stump. You can use a paintbrush to apply this. The mixture will be translocated down into the roots (similar to the way Roundup works) and then kill them.

Triclopyr is also used to kill poison-oak and poison ivy and any other broad-leaved weeds/brush. It can also be used on lawns. I'd advise that you spray or apply it early in the morning so it won't be affected by the heat or winds.

Hope this solves your problem. Good luck!

Ring the tree. Make a nice cut (you're not trying to cut all the way through) all the way around the tree - you're just cutting a ring into it. It should die within months. I don't exactly know why this works, but my dad taught me this. He was a forrester.

Drill several holes in the base and continue to fill them with pure weed killer. It will take about a summer to die off. A slower way is to pound a bunch of 16D nails into the base of the tree. About one every 2 inches will do it in about a year or two.

Answer 5

I will try to answer this without being a smarta.....
There are additives that can be put on them.. Just have to be carefull they dont go thru the root system and kill something you want to save. Go to the YELLOW PAGES and call businesses that sell, cut down, etc trees. I am sure if they dont know they can direct you to someone that does. your local government possibly will have a section that can answer this.

Answer 6

try a copper nail this will kill the unwanted trees. Doesn't work right away though non the less it works.

Answer 7

Just keep cutting until they stop coming back. It only takes a few years. That's what I did with the maple saplings that were all through the lilacs and privet when we first bought our house.

Answer 8

After you cut them down, cut lines in the stump and cover it with rock salt.
