I like the idea of rock salt as it must be cheaper than the $100
containers of weed killer that I'm buying today (2.5 gallons each).

This web site explains the NaCl concentration for weed killer:

While the NaCl appears to be effective, that page also outlines the
major problem when it's applied on a hillside where my plant resides.

Plus, I still need to manually remove the dead plants, which are
(almost) as toxic dead as they were alive - at least for the
foreseeable future.
