Check these first
- Inspect the soil moisture level around the root zone.
- Check for standing water near the trunk.
- Examine the base of the tree for signs of soft or decaying bark.
Likely causes
Poor soil drainage
Most likelyHow to tell: The ground near the trunk remains muddy or swampy for days after rain. You might notice the foliage wilting or turning yellow prematurely.
What to do: Improve the soil structure by adding organic compost to the surrounding area. Ensure the planting site is not in a low spot where water collects. Avoid heavy mulching directly against the trunk.
Overwatering
PossibleHow to tell: The tree shows signs of stress despite regular rainfall or irrigation. The roots may feel soft or smell sour if you dig down a few inches.
What to do: Adjust your watering schedule to allow the top 3 inches of soil to dry out slightly. Water deeply only during extended dry periods rather than on a frequent, light schedule. Ensure the root zone is moist but never saturated.

When to worry
If you see significant branch dieback or the tree is leaning, the root system is likely severely compromised. Minor wilting during a heatwave is normal, but persistent decline requires immediate attention.
Stopping it coming back
Plant your maple in well draining soil and avoid overwatering during the cooler months. Keep mulch away from the trunk to allow for proper airflow.
