I'm in the progress of making more of my house plants survive, better. (I'm doing OK, but too many of my plants die, or sometimes suddenly nearly die for mysterious (to me) reasons.)
I've started looking up a whole bunch of my plants, and while I found vague instructions (e.g. "keep moist" or "water when the top 1in/2.5cm are dry"), but rarely anything specific (e.g. "water every 5 days"). At the same time, there are very clear/specific instructions out there for fertilizing!
My plan right now is to create a list of the various watering rules, monitor each of my plants daily for a month or two, keep track of when I water them, and then build a "static" schedule (water plant A every 2 days, plant B every 7, plant C every 8) that I can set up as recurring reminders.
Is there a better way? Does everybody do this?
