Check these first
- Stick your finger 2 inches into the soil to check for dryness.
- Look at the time of day to see if the drooping is temporary heat stress.
- Check the base of the stem for any signs of rot or damage.
Likely causes
Underwatering
Most likelyHow to tell: The soil feels dry and crumbly to a depth of 2 inches. The leaves look limp and may feel thin or papery.
What to do: Give the plant a deep, thorough watering. Check the soil again in 7 to 14 days to maintain consistent moisture.
Heat stress
PossibleHow to tell: The plant droops during the hottest part of the day but perks up in the evening. This is a natural reaction to intense sun.
What to do: If the plant recovers overnight, it is fine. If it stays droopy, provide a bit of shade during the peak afternoon heat.

When to worry
It is normal for plants to droop slightly during extreme heat. Be concerned if the plant remains wilted even after the sun goes down or the soil is moist.
Stopping it coming back
Maintain a consistent watering schedule every 7 to 14 days. Mulching around the base can help the soil retain moisture during hot spells.
