Check these first
- Look for sticky residue on the leaves.
- Check the soil to see if it is too dry or too wet.
- Inspect the undersides of leaves for small clusters of insects.
Likely causes
Aphids
PossibleHow to tell: You will see sticky honeydew on the leaves and small insects on the undersides. The leaves may look wilted or droopy due to sap loss.
What to do: Spray the leaves with a strong stream of water to knock the aphids off. For heavy infestations, use insecticidal soap once a week until they are gone.
Water imbalance
PossibleHow to tell: The entire branch or tree looks limp and loses its structure. This happens if the soil is either bone dry or completely waterlogged.
What to do: Adjust your watering to ensure the soil stays consistently moist. If the soil is waterlogged, improve drainage by aerating the soil or adding organic matter.

When to worry
If the drooping persists after you have corrected the water and treated for pests, the tree may have a root issue. Drooping that happens during the hottest part of the day and recovers by morning is usually just a normal reaction to heat.
Stopping it coming back
Monitor the tree regularly for pests and keep the soil moisture stable. A healthy, well watered tree is much more resistant to aphid attacks.
