Likely causes
Underwatering
Most likelyHow to tell: The leaves will look limp and feel dry to the touch. The soil will be pulled away from the edges of the pot or feel like dust.
What to do: Give the plant a deep soak until water runs out the drainage holes. Maintain a schedule of watering every 5 to 10 days depending on the heat.
Heat stress
PossibleHow to tell: The plant wilts during the hottest part of the day but perks back up in the evening. This is a natural reaction to extreme temperatures.
What to do: Provide a bit of afternoon shade if the plant is in a very exposed location. Ensure the soil stays consistently moist to help the plant handle the heat.

When to worry
Worry if the plant stays wilted even after you have watered it and the sun has gone down. If it recovers overnight, it is just managing the heat.
Stopping it coming back
Keep the soil consistently moist by checking it every few days during the peak of summer.
