Re: Spider Mites
Good job, it's difficult to tell from where they came as the entire United States was once covered by a huge shallow sea.
The salinity aspect shouldn't really make any difference though when used for killing external pests.
I would guess that I can spray about 50 plants with one spray bottle, so very little would actually get into the soil.
The thing I like about this method is that it remains in place to keep killing until it rains, then washes right off.
