The easiest Calathea to care for is the Calathea lancifolia. The Calathea Lancifolia is not a rare species as it can be found in online stores and house plant nurseries. In addition, the Calathea Lancifolia does not require as much attention as other species do. A proper location, bright but indirect sunlight, proper soil mixture, adequate watering, good potting system, and a standard fertilizer are all that your Calathea Lancifolia needs to survive.
