What do you use to remove a large Pine tree stump so it's roots die to?

The stump grinder wont kill the root,s you need to kill it first.. this works and quick iv just done three in my place trust me, drill or get some body to do it for you straight down the stump 1/2" holes as deep as you can then fill them with round up or its equivalent depending on where you are, place a piece of plastic over the stump and tie it , it will die after a day or two then you can grind it down or just leave it to rot away good luck ...

Chemical rot is very slow. The only fast way to remove a pine stump is with a stump grinder. If you don’t know anyone with one call a tree service, it’s worth it.

The home depot sells a thing called stump removal it comes in a bottle and is a granule... its easy to use just pour and let it work its majic!!! or you can use a sistemic killer(brush killer) in a liquid form and pour it all over the stump

when you dig up the root before you cut it look at the root there will be smaller roots coming off of it cut the main root back to the smaller one and the tree willl be fine and the tap root is on the bottome fo the root system what you will have to watch out for is the root you will be cutting is atched to a limb in the tree so in a few mounths theres a chance the limb will have die back we prune roots all the time make sure you put some compoast in with the soil when you back fill the root

Rent a stump grinder

You could leave the stump there, but cut it like in a waflle kind of shape like in squares ontop of the stump, and poor a bit of gasoline on it. I know it sounds hazardous, to me too, but my dad did that to this huge eucaliptus tree we had, and it hasen't grow since. It kills it.
