i have no issues with plants and a water softener. plants can tolerate way way more salt than a water softener will ever introduce into the water. and if one really doesnt want water from their softener, ive never seen a water softener that didnt have a bypass on its head. push the bypass valve over, run a few gallons to flush the pipe out, and you have non softened water. folks make way too big of a deal over water softeners.
