The one topic that lives only in a hundred contradictory blog posts, filed into a single honest report. What's really in your tap (four things), which plants genuinely care (most don't — ranked), how to read your own hardness straight off the inside of your kettle, the alternatives honestly rated, and the rain-barrel licence you cut out. From a reformed water-worrier with several smug calatheas.

Who's behind this

I'm not a botanist, and I don't have 150 plants — I keep a windowsill's worth, and I've killed a few learning how (a Calathea in eleven days is how this whole thing started). When something goes wrong I go down the rabbit hole: the studies, the extension-horticulture pages, the 2am forum threads, and every horror story plant people send in on @leafjournal on TikTok. These guides are that mix — hands-on experience checked against the research, cleaned up and told straight. No lab, no sponsorships, no “trust me.” Just what actually keeps a plant alive, so yours isn't the one that learns it the hard way.
