Likely causes
Underwatering
Most likelyHow to tell: The soil feels dry or dusty to the touch, and the stems look limp and tired. The leaves may also feel thin or papery.
What to do: Give the plant a deep soak immediately until water runs out of the drainage holes. Adjust your schedule to water every 3 to 7 days to keep the soil consistently moist.
Heat Stress
PossibleHow to tell: The plant droops during the hottest part of the day but perks up again in the evening. This is a temporary reaction to intense sun.
What to do: Ensure the soil stays moist to help the plant handle the heat. If the drooping persists into the evening, provide a bit of afternoon shade.
When to worry
It is serious if the plant stays wilted even after you water it, as this could indicate root damage. Temporary wilting in the afternoon heat is normal for many plants.
Stopping it coming back
Mulch the base of the plant to help retain soil moisture and keep the roots cool.
