Check these first
- Check if the plant is in direct afternoon sun.
- Feel the soil to see if it is bone dry.
- Observe if the leaves unfurl when the temperature drops.
Likely causes
Heat Stress
Most likelyHow to tell: The leaves curl inward during the hottest part of the day to conserve moisture. They often look better in the morning or evening when it is cooler.
What to do: Move the plant to a spot with partial shade during the afternoon. Water the plant deeply in the morning to help it handle the heat.
Underwatering
PossibleHow to tell: The leaves feel dry and brittle while curling at the edges. The soil will be completely dry and pulling away from the sides of the pot.
What to do: Give the plant a thorough soak until water runs out of the drainage holes. Maintain a consistent watering schedule every 3 to 7 days.

When to worry
If the leaves stay curled even at night or after watering, the plant is under significant stress. Minor curling during a heatwave is a normal defensive response.
Stopping it coming back
Provide consistent moisture and protect the plant from the harshest direct afternoon sun. Mulching the soil can help keep the roots cool.
