OH God.. don't do the salt!! I did that and it left a terrible
yellow/white ring around everything in the area.. grass.. weeds.. man..
it looked deliberate. There are a lot of ways to kill the darn thing.
Keep bumping the roots with your lawn mower and oops! Don't you see
bug infestation right there that needs spraying?
I killed a couple of my trees/bushes by accidently pouring Muiatic Acid
off the side of my deck. AND it had been diluted with water!! It started
showing signs of distress aobut two weeks later. I KNEW what I had done
and had to pay for it... you could try that. These tree huggers haven't
a clue what you are going through. I do.. And I am going to do what I
can to 'get it' done.. sue me....
