How do I get rid of sumac bushes permenantly?

I have cut them back and it seems that 5 grow for every one cut. They are invading my yard.

    sometimes you have to resort to poison. After you cut them back, pour Roundup on the stumps. That will help kill the part living underground. You may experience new growth a little further away from the dead stump, but follow the same process and eventually the plant will die. Don't let the new growth get big. Big above ground means big underground.

    A salt saturated solution used several times on the stumps will not only kill the bush but sterilize the soil so it cannot grow back. I have used table salt and water conditioner salt - will kill even bamboo!

    THey are difficult to get rid of . I dug up a huge hill of sumac last summer - and the roots were massive! WE had to use a chain saw to get some of them out.
    I dug down and got most of the roots out, but they are coming back some this year. With a few years of maintenance and digging them out when I see them, I'll be home free. I don't want to use any kind of weed/root killer as I'm more organic, and want to plant in the same area right away.
