Calathea problems and care signals

Calatheas curl and brown from dry soil, low humidity, mineral-sensitive water, heat, cold, or pests. They prefer steadier moisture than many common houseplants.

Do not assume

Do not copy a care rule from another plant. Use this profile to adjust the general symptom framework before watering, repotting, fertilizing, or treating.

Plant-specific checks

Check whether leaves curl during the day and relax later.

Inspect undersides for mites before blaming humidity alone.

Look for vent exposure, hot glass, or mineral crust.
