Best Soil Mix for Calathea: Moisture, Drainage and Repotting
Quick answer: Calathea soil should retain more moisture than a succulent mix while still containing enough air space to prevent soggy roots. A balanced indoor potting mix amended for drainage is usually a better fit than either extreme.

What Calathea soil needs
- Even moisture
- Good drainage
- Air around roots
- Enough structure to resist compaction
Signs the mix is too dense
If the pot stays heavy and wet for many days, water sits on the surface, or leaves yellow while soil remains damp, the root zone may need better aeration.
Pot size matters
A pot that is much larger than the root system can hold excessive wet mix. Increase container size gradually.
Should Calathea soil dry completely?
Calatheas generally prefer more consistent moisture than snake plants or succulents, but they still should not sit in waterlogged soil.
