How to care for your Calathea
Everything you need to keep your Calathea healthy: watering, light, humidity, feeding, repotting and pruning.
Calatheas, native to the tropical forests of South America, are exceptional ornamental plants thanks to their geometrically patterned leaves and often purple undersides. They have the fascinating behavior of closing their leaves at night. However, they are demanding: they require high humidity, soft water, and consistent indirect light.
Watering your Calathea
Every 7 days
Use filtered, distilled or rainwater only — this species is highly sensitive to fluoride and chlorine. Keep the substrate lightly moist at all times.
How to know it needs water
- Leaves beginning to curl inward
- Surface of substrate dry to the touch
How much light a Calathea needs
Medium light
Indirect light only; never expose to direct sunlight which fades and scorches the delicate leaf patterns.
- Direct sun tolerated
- No direct sun
- Orientations that suit it
- North, North-east, East, North-west
Humidity and misting
60–80 %
High (60–80%) Mist with demineralised water only to avoid white limescale deposits on the decorative foliage.
Feeding and fertiliser
Every 30 days
Apply monthly from April to October; withhold entirely in winter.
- Recommended feed
- Balanced liquid fertilizer diluted to half strength · 3-1-2
Repotting your Calathea
Every 18 months
Use a well-draining, humus-rich substrate; use soft water only when settling in after repotting.

The tell-tale signs
- Roots emerging from drainage holes
- Noticeably slowed growth
Pruning your Calathea
Remove brown-edged or damaged leaves promptly throughout the year. Cut cleanly at the base of the petiole with sterilised scissors; never tear leaves.
Through the year
Watering is not set once and for all: it follows the light and the growth. Allow 11 days between waterings in the depth of winter, against 6 in the growing season.
