Drafts are the silent killer for satins-OP, if you’ve got any AC vents or windows nearby, that’s your variegation thief right there. Mine’s in a draft-free corner at 70F steady, and after 4 years, it’s still denser than my golden ever was. But let’s push back on the “low-maintenance” hype: I’ve tracked three satins side-by-side (one low light north-only, one supplemented, one east with rotation), and the north solo one lost 30% variegation in year 1 per my monthly pics-log it yourself next time. Evidence? Golden pothos bounces back faster from stress; satin’s pickier on stable microclimate.
New tip unmentioned: filtered water only (RO or rain), since tap chlorine nukes those velvety cells over time-tap users, what’s your water hardness? Switched mine and watched new growth explode silvery. Rotate weekly too, or one side etiolates sneaky. OP, water source and rotation in play? Long-termers, chime in with your water hacks or growth charts-debate time!
