Peacock prayer plant needs filtered light and steady root conditions. Check the potting mix when leaf edges dry rather than misting as the only response.
Peacock prayer plant needs a steady position
Goeppertia makoyana, often sold under its older Calathea name, is grown for patterned leaves. Give it useful filtered light, away from cold glass and drying heating airflow. Avoid a sudden move into intense sun.
Keep root moisture balanced
Use an airy medium with drainage. During active growth, avoid repeated hard drying, but do not leave the pot standing in stagnant water. Check below the surface before treating a curled leaf as a demand for another soaking.
Read leaf edges in context
Water quality, dry air, root stress and exposure can all contribute to marks. Review the pattern and recent changes instead of adding several products at once. Misting does not repair roots or permanently change a dry room.
Let new leaves unfold
Do not pull apart a furled leaf. Remove clearly deteriorated material and clean mature leaves gently where needed. Judge recovery from sound later growth; old brown edges usually remain. Divide only a healthy substantial clump, with suitable growing points and roots retained.
