QuestionI have a pretty generic question actually. What type of water is best for house plants? Do they prefer treated water (like city water) or well water that has or has not been treated by a water softener?
Thanks!
AnswerHi Jenni,
That is an interesting question that does not have a simple answer.
The problem is that every water system is different, sometimes in significant ways.
The most generically consistent water sources are rainwater and distilled water. They are great for [plants, but often not practical to obtain.
Hard water and water that is alkaline are very bad for plants as they change the pH of the soil over time and prevent nutrients from getting absorbed.
Most water softeners add certain mineral salts to soften hard water. These mineral salts are also bad for plants. So avoid water treated by softeners.
Chemically treated municipal water supplies typically add chlorine and fluoride. Although there is some evidence that these two chemical additives can cause leaf spotting on certain plants (Dracaenas, spider plants, et.al.), this only seems to occur where unusually high concentrations of chlorine are used. Chlorine will dissipate into the air if left in an open container overnight. Fluoride and other minerals will not dissipate this way.
Like I said, there is no single or simple answer to your question.
Please let me know if any of this is unclear or if you have any additional questions.
If this information has been helpful, please take the time to give me a rating and nomination.
