Check these first

  1. Feel the soil around the base of the plant.
  2. Check if the drooping happens only in the afternoon heat.
  3. Look for any recent digging or damage near the roots.

Likely causes

  1. Extreme drought

    Most likely

    How to tell: The leaves look limp and soft, especially during the hottest part of the day. The soil feels very dry and hard to the touch.

    What to do: Give the plant a deep watering, soaking the soil to a depth of 6 inches. Check the soil moisture every 7 to 10 days during hot, dry weather.

  2. Root disturbance

    Possible

    How to tell: The plant started drooping shortly after being moved or after heavy digging nearby. The roots may have been damaged.

    What to do: Keep the soil consistently moist but not soggy for a few weeks to help the roots recover. Avoid disturbing the soil around the base of the plant.
