Mapping of the global potential of atmospheric water harvesting using solar energy shows that it could provide safely managed drinking water for a billion people worldwide based on climate suitability.

The point I want to make is that, in caring for plants of any kind, anywhere, we shouldn’t look for one-size-fits-all advice. Instead, seek answers based on how plants actually work. The question of ‘how often should I?’ shows a very different approach. It says, let’s keep this simple, give me a schedule and I’ll follow it. Often it also means, I can’t be bothered to know more than that; if it can’t be that simple, I don’t want the plant. (Incidentally, this is why I say just water your plants when they’re clearly getting dry, because at least that’s relatively simple.) https://dirtwise.substack.com/p/why-is-houseplant-advice-so-bad
