Likely causes
Underwatering
Most likelyHow to tell: The entire plant looks wilted and the soil feels bone dry. The leaves may feel brittle or thin.
What to do: Give the plant a deep soak until water drains through the soil. Check the moisture levels again in 7 days to see if it needs more frequent attention.
Heat stress
PossibleHow to tell: The plant droops during the hottest part of the day but perks up at night. This is common during extreme heat waves.
What to do: Provide a bit of afternoon shade if possible. Ensure the plant is well hydrated before the heat of the day hits.

When to worry
Drooping during the heat of the day is a normal survival mechanism. If the plant stays droopy all night, it is likely suffering from severe dehydration.
Stopping it coming back
Maintain a regular watering schedule and mulch around the base to keep the soil cool. This helps the plant handle temperature swings better.
