Beginner Gardening: Soft Water vs Untreated Water - HELP!, 0 by dovebydesign

My outside faucets are untreated water, which is what I thought I should be using in my gardens and lawns because you do not want to put salt back into the beds or chemicals of any kind. (Yet I want to in my body? hmmmm) Anyways, I just added two nice newly painted arbours to my shade garden which requires a huge amount of water, aprox 6 hours twice a week. I have put up with the plants all having rust stains on them, and the mulch but darn, those white arbours are so pretty. So my DH says he can put a soft water spicket out front for me to use for that garden. It is mostly Hosta ( aprox 100 or so) and a few ( aprox 20) Heuchera, an odd Brunnera and some Astible, Dicentra and Columbine, all under 2 Blue Spruce and 2 Maple trees. So are there any science oriented folks whom would know whether or not I would be harming if I watered with soft water? I need to water the entire area because I do not want the tree roots to adjust and find the areas I spot water if for instance I was to put a drip system for each plant or use soaker hoses. Ok....too much info I am sorry, but I really do need to know. Thanks so much in advance for any help!
