- Check the area around the trunk for standing water.
- Examine the leaves for signs of yellowing or premature drop.
Likely causes
Poor soil drainage
PossibleHow to tell: The ground around the tree stays soggy for days after rain or watering. You might notice the foliage wilting even when the soil is wet.
What to do: Improve drainage by amending heavy clay soil with organic compost. Avoid piling mulch directly against the trunk, as this traps excess moisture.
Overwatering
PossibleHow to tell: The leaves turn yellow and drop prematurely while the soil remains constantly saturated. The roots may look mushy or dark instead of firm and white.
What to do: Adjust your watering schedule to allow the top few inches of soil to dry slightly between waterings. Ensure the tree is not planted in a low spot where water collects.

When to worry
It is serious if the tree shows significant dieback in the canopy or if the bark near the base feels soft. Some leaf drop is normal during late summer or autumn.
Stopping it coming back
Plant your birch in well draining soil and keep mulch a few inches away from the trunk to allow for airflow.
