- Check the soil moisture to ensure it is not waterlogged.
Likely causes
Fungal Leaf Spot
Most likelyHow to tell: You will see brown or black circular spots appearing on the foliage during humid or rainy seasons. These spots may grow larger or merge over time.
What to do: Remove and destroy any fallen leaves around the base of the tree to stop spores from spreading. Improve air circulation by pruning crowded branches and avoid overhead watering.
Environmental Stress
PossibleHow to tell: Spots may appear if the tree is struggling with extreme temperature changes or poor soil drainage. The leaves might look generally weak or discolored around the spots.
What to do: Ensure the tree is planted in well draining soil and maintain a consistent watering schedule of every 7 to 14 days. Apply a layer of mulch to help keep the root zone cool and moist.

When to worry
It is normal to see a few spots late in the season as the tree prepares for dormancy. Worry if the spots cover more than half the leaf surface or cause premature leaf drop.
Stopping it coming back
Keep the area under the tree clean and ensure good airflow between branches to discourage fungal growth.
