Likely causes
Underwatering
Most likelyHow to tell: The leaves look limp and soft, and the soil feels dry an inch or two below the surface. This happens quickly during hot, dry spells.
What to do: Give the plant a deep watering until the soil is moist down to the roots. Aim to water every 3 to 7 days depending on the heat.
Root Damage
PossibleHow to tell: The plant droops even when the soil is wet, which suggests the roots cannot take up water. This might be due to soil compaction or root rot.
What to do: Check the soil drainage to ensure it is not waterlogged. If the soil is muddy and smells bad, stop watering and let it dry out slightly.

When to worry
If the plant stays drooped even after a thorough watering and a cool night, the roots may be damaged. Temporary wilting during a hot afternoon is normal.
Stopping it coming back
Keep a consistent watering schedule and use mulch around the base to retain soil moisture.
