Calathea (Calathea makoyana) is a fussy plant with a specific set of guidelines that must be met for it to survive. However, once you've mastered care and feeding of the calathea plant, you'll be rewarded with strikingly beautiful leaves, which are purple underneath with green stripes on top. Native to the jungles of Central and South America, calathea is appropriately nicknamed "peacock plant."
Increase humidity around calathea by setting the container on a saucer filled with wet pebbles. Don't allow the pebbles to dry out, but keep the water level low so that the water doesn't touch the bottom of the container. Never allow the container to sit in standing water.
Keep the potting soil evenly moist at all times. Calathea will also benefit from being sprayed daily with a fine mist. Always water calathea with room-temperature distilled water as the minerals in tap water are harmful to the plant.
Feed calathea monthly during spring, summer and fall, using an all-purpose liquid fertilizer for indoor plants that has been diluted to half strength. Don't fertilize calathea during the winter months.
Repot calathea every spring, using a potting mixture made of three parts commercial potting soil and one part peat moss. The container should be just one size larger.
Keep calathea in a warm room with temperatures between 70 and 85 degrees Fahrenheit.
