Likely causes
Severe Drought
PossibleHow to tell: Leaves turn yellow or brown and fall off rapidly during a dry spell. The plant is shedding foliage to conserve water.
What to do: Water the plant deeply immediately. Continue to monitor the soil every 3 to 7 days to ensure it stays moist.
Fungal Leaf Spot

When to worry
If the plant loses a large percentage of its leaves in mid summer, it is a sign of significant stress. It is normal for Winterberry to lose its leaves in late autumn as it is a deciduous shrub.
Stopping it coming back
Keep the area around the base clean of debris and maintain consistent soil moisture.
