Thank you for your article on recycling water for use in gardens (“Save some for the passion fruit,” July 16). There is one major concern your article doesn’t address, and that I haven’t seen in several water reuse articles, and that is the danger to plants when reusing softened water. If one has a soft water conditioner in the home, all of the water from showers and sinks has been treated with salt. The danger in using this water in your garden is that the salt builds up on roots and can kill plants as well as contaminate the soil until a good amount of rain can leach out the salt. Local residents may want to turn their soft water systems to ‘vacation’ mode to save water and to save their plants when reusing ‘gray water.’ Of course, hard water mineral deposits will spot glasses and appliances but it is either that or dead plants. I refer you to the article: gardeningknowhow.com/plantproblems/environmental/softened-water-and-plants.htm.
