Use boilingwater, or a salt or vinegar solution. (04/07/2005)

Plain old vinegar poured on the cracks will work. Your yard will smell like a German salad for a day, but that will fade away. :-)
It does wear off, but we've only had to treat our sidewalk twice each summer. (04/08/2005)
I use white vinegar, just pour it from the bottle onto weeds, it's cheaper then weed killer and also does not hurt pets. (04/08/2005)
