Likely causes
Underwatering
Most likelyHow to tell: The leaves will feel limp and look dull, and the soil will be dry to the touch. This happens quickly during hot, sunny weather.
What to do: Give the plant a deep soak until water runs out of the drainage holes. Aim to keep the soil evenly moist by watering every 3 to 7 days depending on the heat.
Root rot
PossibleHow to tell: The plant droops even when the soil is wet, and the stems near the base may look mushy or discolored. This is caused by poor drainage.
What to do: Stop watering immediately and check the soil drainage. If the plant is in a container, ensure it has large holes and use a well draining potting mix.

When to worry
Drooping is normal during the hottest part of the day if the plant recovers by evening. Worry if the plant stays wilted all morning.
Stopping it coming back
Maintain a consistent watering schedule and ensure your soil drains well. Adding organic matter to the soil helps hold moisture without becoming waterlogged.
