If your houseplant leaves are turning brown, the problem might be lurking in your tap water – here's what you should be using instead

Is tap water bad for houseplants.

I've been collecting houseplants for a few years now and still continue to learn new things that help improve my plant care regime. Not too long ago, I discovered certain types of water can impact different plants in different ways.

I first started to research this when I spotted my rattlesnake calathea turning brown at the tips. Everything in its growing environment was up to scratch, so I knew it had to be a different issue. That's when I learned tap water can be bad for houseplants, particularly those indoor plants that are sensitive to environmental changes, like my calathea.
