Q.Is Kitchen/tap Water Bad For My House Plants? Are Outside Hose And Rain Water Best?

Zone 92071, zone 10? Away from the ocean, in Santee, a part of San Diego county, CA. | Anonymous added on January 3, 2022 | Answered

I’m in Santee, So CA, an inland part of San Diego. All my outside plants are in pots, as are the inside plants! Not much rain…..Our coolest temp is about 35 or so, occasionally, without any ice or frost. Thank you, I’ve been getting your email for about 1 1/2 years. I don’t think I have a password?

It depends on your houseplant. Some plants are sensitive to the additives in tap water such as chlorine or fluoride and should be watered with distilled water. Most plants, though, don't mind tap water. Your outside hose water would be the same as the tap water. Rain water, if you catch it, won't have the added chemicals in it like tap water so your plants probably appreciate it.
