Check these first
- Check the top inch of soil for dampness.
- Smell the soil near the base for any signs of decay.
- Inspect the drainage holes to ensure they are not blocked.
Likely causes
Overwatering
Most likelyHow to tell: The leaves may turn yellow or wilt even when the soil feels wet. You might also notice a sour or swampy smell coming from the base of the tree.
What to do: Stop watering immediately and let the top 3 inches of soil dry out completely. If the tree is in a container, ensure it has large drainage holes and that you are not leaving it sitting in a saucer of water.
Poor Soil Drainage
PossibleHow to tell: Water pools on the surface for a long time after you water the tree. The soil feels heavy and dense rather than loose and airy.
What to do: Amend the soil with perlite or coarse sand to improve aeration. If the tree is potted, repot it into a fresh, well draining potting mix designed for tropical trees.

When to worry
It is serious if the trunk base feels soft or mushy to the touch. Minor wilting after a heavy rain is normal and usually resolves as the soil drains.
Stopping it coming back
Always wait until the top inch of soil is dry before watering again. Ensure your planting site or pot has excellent drainage to prevent water from pooling.
