Calathea 'Quieta' care
Among the quieter members of the genus, Calathea 'Quieta' forms an upright clump and settles quickly indoors.
Position it in bright indirect light and rotate the pot monthly for even growth. Water when the top third of the mix is dry. Yellowing lower leaves almost always mean too much, not too little.
Keep it at 55% humidity or higher; pot it in a chunky aroid mix and refresh the top layer each spring. New leaves emerge paler and darken over their first fortnight.
