Plant + symptom guide
Crispy calathea leaves mean the plant has crossed from minor tip damage into wider moisture or placement stress. Decide whether the whole leaf dried, scorched, or declined with pests.
For calathea, read this symptom alongside how the plant usually behaves: Calatheas curl and brown from dry soil, low humidity, mineral-sensitive water, heat, cold, or pests. They prefer steadier moisture than many common houseplants.
Check whether the pot became completely dry or pulled away from the sides.
Look for crisping on the side facing a window, heater, or fan.
Inspect undersides for pests if crisping appears with speckling, curling, or dull leaf color.
Check whether leaves curl during the day and relax later.
Inspect undersides for mites before blaming humidity alone.
Evergreen diagnosis
Crispy calathea leaves are different from a few brown points. When larger sections dry, the plant has usually experienced a full dry-down, hot airflow, direct sun, mineral stress, or pest damage that went on too long.
The damaged tissue will not recover, so the goal is to decide whether the plant still has healthy crown growth and what condition caused the leaf to dry out.
If the mix pulled away from the pot or water runs straight through, the center may be dry even after watering. Calatheas can crisp quickly after that kind of dry-down.
Rehydrate slowly and drain fully. Then keep moisture steadier, allowing the surface to begin drying without letting the whole root ball collapse dry.
Spider mites can make leaves look dusty, stippled, curled, and eventually crispy. This damage often starts before obvious webbing appears.
Check undersides with bright light before blaming humidity alone. Remove fully dead leaves, but keep partly green leaves while the plant rebuilds.
Rehydrate dry soil slowly so water reaches the center of the root ball.
Move to bright filtered light and steadier moisture before cutting off every damaged leaf.
Remove fully dead leaves at the base, but keep partly green leaves while the plant rebuilds energy.
