Overwatering

When to worry
If the yellowing spreads rapidly across the entire canopy, it could indicate a serious root issue. A few yellow leaves in late summer are normal as the tree prepares for autumn.
Stopping it coming back
Maintain a consistent watering schedule of 7 to 14 days and apply a layer of mulch to keep soil moisture stable.
