Signs of Overwatering
This plant genuinely wants to sit in a shallow tray of water, so 'overwatering' in the usual sense is rare - the real risk is using tap water, which builds up mineral salts and kills the roots over time.
Signs of Underwatering
The traps and leaves shrivel and blacken quickly if the peat moss is allowed to dry out - unlike most houseplants, this one has almost no drought tolerance.
Adjusting for the Seasons
Needs a genuine cold dormancy of 3-4 months in winter (a cool garage, unheated porch or the fridge's vegetable drawer for potted specimens) or it will weaken and die within a couple of years - this is not optional, unlike the 'slow down' winters of typical houseplants.
Pro Tip
Only ever use distilled, reverse-osmosis or rainwater - the minerals in tap or even most bottled water are the single most common cause of death for this plant, far more than incorrect light or triggering the traps too often.
