If it killed your plants, the water, it will kill you. I gotta say bs unless your in a third world country or flint MI. You or something else killed them not the water imo
OK, I hear you. I'm not here to start an argument.
The tap water here doesn't kill the plants in the garden, they still grow, but the rate of growth is noticeably slower, and less vigorous during tap watering months. I have to rely on the tap often as it doesn't rain enough here to water everything with rain water year round. The herb garden becomes more wimpy when it's running on tap water. Every time we get some rain and I can give the cacti pots and the garden some sky water, growth quickly explodes and everything looks more lush, the plants always seem much happier.
So I use the tap water if I have to, and it keeps everything alive, the herbs will still grow, but rain water is much better for the garden, and especially the cacti. They love it.
After noticing this trend for years- as an experiment, I had a spot full of some Peruvian Torches in pots I cloned from a giant parent in 2016, and I gave certain ones only tap water. The tap watered clones grew at an average rate of about 1/2 foot per limb each year and were green. The clones that got rain water grew 1foot or more (up to 1.5 ft!) per limb each year, threw off more pups, and were noticeably fatter and more "blue". Same parent, same soil, same nutrients, same amount of sun, but different water.
This is just what I have observed.
