Check these first
- Check the soil moisture with your finger to see if it is dry.
- Inspect the undersides of the leaves for any signs of pests or rust fungus.
- Observe if the curling happens only during the peak heat of the day.
Likely causes
Moisture stress
Most likelyHow to tell: The leaves look shriveled or crispy at the edges and the soil feels dry to the touch. This happens when the plant misses its regular watering window.
What to do: Water the plant thoroughly until moisture runs out of the drainage holes. Maintain a consistent schedule of watering every 2 to 5 days to keep the soil damp.
Excessive heat
PossibleHow to tell: The leaves curl inward during the hottest part of the day even if the soil is damp. The plant is trying to reduce its surface area to save water.
What to do: Move the container to a spot with partial shade during the afternoon. You can also mulch the base of the plant to help keep the roots cool.

When to worry
Worry if the leaves stay curled even after you water the plant and the temperature cools down. It is normal for leaves to curl slightly if the plant is temporarily stressed by a heat wave.
Stopping it coming back
Keep the soil consistently damp and provide a bit of afternoon shade if your area gets very hot.
