pelleted salt, used in a water softener will last longest. the smaller you get in size, the shorter the time to dissolve, and wash away..

I bought the 50 lb bags of salt which are supposed to be for water softeners for about $8 a bag. Not sure it was pelleted, but very coarse chunks.

pelleted looks like a vitamin pill,(oblong shape) but 3X the size. less exposed area=lasts longer..

radios1, Thanks for the information. I will look for those after I use up the bags I already have.

I know that when I make ice cream and dump out the ice with rock salt it kills whatever was there.

I have not tried bringing up saltwater from the beach to kill weeds. I know on one of my properties we have a low spot next to that beach that on a high tide combined with a north wind the mouth of the creek becomes somewhat of an estuary. Canadian thistles and many of the grasses will not grow there.

They use salt on the roads in winter to melt the ice. By spring the softwood trees near many roads and especially the interstate are all brown from the spray kicked up by vehicles. Some recover, while others just die.
A few years ago somebody on this site mentioned using salt to keep the weeds down in their asparagus. Apparently that crop is more resistant to salt than most plants.
