I've salted our concrete pad, works well. Nothing grows in the cracks. Nothing grows where the path is from the house to the drive, salted in the winter.lighthawk said:Anytime I take down one of the willows in my yard they keep throwing up suckers so a friend told me to cover the stump with rock salt. Killed the stump and all the grass around it. Can't see why an application of rock salt on your driveway wouldn't do the same. Just thinking out loud. Anyone else ever tried this?
