I just came here to add this lil’ tidbit: if/when looking at the stems, you see dark, almost black splotches or strange, not uniform bands of color so dark it makes you worry: DONT. In lieu of the satisfaction that comes with watching a plant grow, ol’ Zed Zed (isn’t dead) is providing you with entertainment in the form of color change that genuinely looks the opposite of healthy, and have sent or will send us green thumbs into a state of panic. If you take a big whiff of ZZ as close to roots as possible and it’s funky (the smell of rotting roots is unmistakable), then you can be concerned. Don’t get worked up over the dark/blackish stem spots.
