Ever notice how rocksalt kills grass around sidewalks?

Dump a 25 pound bag in a wash tub mix hot water to help it dissolve
and try and get most of it down line, then go out for day so the
salt stays in contact with the roots kiiling them

been doing this for 10 years now with no problems, just repeat 3
to 4 times a year, to keep the roots from regrowing.

you can use rock or softener salt, it can do no harm and may just
save you the cost of a new line

my 80 foot line estimate was about 8 grand I can buy salt forever
to save that much $

Just going through this ordeal. I'd like to try the rock salt. My
concern would be that the roots are growing down from the top of the
pipe and the rock salt will sit on the bottom of the pipe. Won't
make contact with the roots causing the problem.

Would roots really grow from the top of the pipe? Do most tree roots
like to grow through air?- Hide quoted text -

most roots are above the height of the sewer line and naturally grow
down to water.... besides trees breathe air thru roots.

I suspect that roots are more likely to seek out the leakage at the bottom of
the pipe to get the water and nutrients than to foloow (what?) into the barren
dry top of the pipe. Sure they grow down. They get near the bootom of the pipe
and discover what they want, then grow up if needed into the pipe.

It might be interesting to see some pictures of roots in a pipe. I bet they are
mostly coming in the bottom, then growing up as the block the flow and rais the
level within the pipe.
