dixie, the best tree killer is triclopyr. This used to be the active ingredient in Ortho's Brush-B-Gon. I am referring to the concentrated form, generally about 8% active ingredient, not the premixed types. Not sure if it is still available. Have also seen the Enforcer brand of brush killer to be 8% triclopyr.

When cutting down a weed tree, make your lowest cut a perfect horizontal. If you flood this stump with the full strength triclopyr-based product, you will have a 95% success rate in stump killing. If you drill several large holes into the stump, and fill these as well as the flooding, you will probably have a 100% success rate. (Probably, because nothing in nature is 100%, or it wouldn't be nature.) We have large eyedroppers for application in the holes.

You can kill a standing tree by drilling into it in a downward angle and injecting the herbicide. But it is usually easier to cut down a living tree than a dead one, so we do the stump treatment. If you do kill the tree first, be sure to cut it down soon after. Dead tree is harder wood if it sits very long.

Some of the old timers in my area cut the tree flush with the ground, drill holes in the stump, pour in "salt of petre" (I think that is how it is spelled) They then cover the stump with compost. The salt of petre kills the stump and the compost rots the wood.


So said the drugist.

There is a product called blue root and it is small blue crystal rock salt sized granuals. You pour them down the cleanout pipe and they will lodge aginst any roots in your line. Over a period of time they eat up these roots preventing the blockage. It need be applied once a year or sooner if desired to prevent future or reoccuring problems. Just check with any well stocked local mom & pop hardware store. If they don't have it they can probally order it for you.
