underwatering and Calathea
Quick answer
If underwatering is what's going on with your Calathea, the most likely cause is: Calathea (Goeppertia) leaves signal drought stress by rolling their edges inward and developing crispy brown tips, because the thin, broad Marantaceae foliage cannot store enough water to ride out even short dry-downs between waterings; in the wild these plants grow on consistently damp tropical forest floors.
Start here:
- 1. When the leaves start rolling inward at the edges, water the plant thoroughly until excess drains from the holes; allow the top half of the pot to dry before the next soak rather than letting the rootball fully desiccate.
- 2. Reduce watering frequency in winter so the soil dries out a little more between drinks, but never let the plant sit bone-dry long enough for the foliage to crisp; check soil moisture with a finger or moisture meter before each watering.

How to correct underwatering on Calathea
- 1
When the leaves start rolling inward at the edges, water the plant thoroughly until excess drains from the holes; allow the top half of the pot to dry before the next soak rather than letting the rootball fully desiccate.
- 2
Reduce watering frequency in winter so the soil dries out a little more between drinks, but never let the plant sit bone-dry long enough for the foliage to crisp; check soil moisture with a finger or moisture meter before each watering.
- 3
Switch to distilled, rainwater, or filtered water (free of fluoride and chlorine) so the rolling-leaf dehydration signal is not compounded by tap-water leaf margin burn that mimics underwatering.
Keep underwatering from repeating on this Calathea
Establish a stable watering rhythm that keeps the soil moist but never waterlogged: water when the top 2 inches dry, group the calathea with other humidity-loving plants, and run a humidifier nearby so transpiration stays low and the root demand for water stays steady.
