I hate to waste water especially here in the desert (Az) so I'd like to use the water I drain from our tub to water some trees/shrubs aprox 3yrs old. I'll test it first with a Taylor 1766 kit. Does anyone know how many PPM is safe? I realize it will depend on the plant so I'm trying to get a general idea.
How many ppm of salt is harmful to landscape/trees?

If you have 3500 ppm of salt in your 350 gallon spa that would be 10 lbs of salt. If you spread the water around I doubt the salt will harm any of the general plants you might have.

I suggest not doing that.
It’s too dry here in the desert and we don’t get enough precipitation annually to dilute water with a lot of dissolved solids in it. Also, we have heavy clay soil and caliche here which means the upper most regions of the soil where roots tend to grow will hold on to the sodium and calcium you’d be dumping into it. That will cause the build up of sodium ions in the soil increasing its sodicity greatly. There are only a few species of plants here on the desert that can handle highly saline soils and they are generally NOT the kind of plants people like in their yards (eg, desert broom or “salt bush”). Adding lots of saline water to the soil will stress existing plants that critically rely on subsurface water storage. Sodic soils make it much harder for plants to uptake water.
Send it down the drain into the city sewer lines or your septic tank … it’s not wasting at all. The water that goes into the sewer lines is eventually processed and discharged into one of the many dry rivers we have around here where it waters the riparian habitats. It needs to be processed though and the water treatment plants are the best places for that to happen.
