Likely causes
Dehydration
Most likelyHow to tell: The entire plant looks limp and the soil feels dry to the touch several inches down.
What to do: Give the plant a deep soak right away. Ensure the water reaches at least 6 inches into the soil to hydrate the deep root system.
Heat stress
PossibleHow to tell: The plant droops during the hottest part of the afternoon but perks up again at night.
What to do: Apply a thick layer of mulch around the base to keep the roots cool. If the plant is in a container, move it to a spot with slightly less intense afternoon sun.
When to worry
If the plant stays wilted even after a thorough watering and cool night temperatures, the roots may be damaged.
Stopping it coming back
Maintain a consistent watering schedule every 3 to 7 days to keep the soil moist.
