Calathea, Prayer plant, Ctenanthe
Light:
Maranta plants prefer bright indirect light. Too much direct sun burns the leaves and causes the beautiful leaf colours to fade.
Water:
Maranta are very sensitive to the water you use. The best way to water is to use distilled water, rain water, or allow your tap water to sit out overnight before using it. Keep the soil moist but never soggy. Allow the top 1-2” to dry out before watering. Never let a Maranta sit in water. High humidity is a must! A Maranta plant gets brown leaf edges when the air is too dry. Humidity can be increased by placing your plant on a tray of wet pebbles (be sure the pot is on the pebbles and not in the water), setting a humidifier close by, or by grouping plants together to create a greenhouse effect.
Temperature:
Maranta like temperatures between 18°- 26℃, and do not like cold drafts or temperatures below 12°. Hot temperatures cause the leaves to curl.
Fertilizer:
Feed monthly in the spring, summer, and fall with a basic houseplant food diluted to ½ the recommended strength. Don’t fertilize if the plant is not growing.
Potting:
Maranta’s rarely need repotting but when necessary use a good light porous indoor potting soil that retains water but still drains quickly. African Violet soil works well.
