Pocket Botanist
Check these first
- Inspect the leaves for a dusty white texture.
- Check if the plant is crowded by other shrubs.
- Feel the soil to ensure it is not staying soggy.
Likely causes
Powdery Mildew
Most likelyHow to tell: You will see a white, floury coating on the surface of the leaves and stems.
What to do: Prune away the most heavily infected leaves to improve airflow. Spray the remaining foliage with a mixture of one tablespoon of baking soda per gallon of water, applying it once a week until the spots disappear.
Leaf Spot Fungi
PossibleHow to tell: These appear as distinct brown or black circles with yellow halos rather than a dusty white coating.
What to do: Remove the affected leaves immediately and dispose of them in the trash, not your compost. Avoid overhead watering to keep the foliage dry during the day.

When to worry
If the spots cover more than half the leaf surface, the plant may struggle to photosynthesize. Minor spotting is common in late summer and usually does not kill the plant.
Stopping it coming back
Ensure your plant has plenty of space for air to move through its branches and avoid wetting the leaves when you water.

Questions people ask
- Will these spots kill my plant?
- Usually no. Powdery mildew is mostly an aesthetic issue that weakens the plant over time if left untreated.
- Should I use a fungicide?
- You can use a neem oil spray if the infection is severe, but improving airflow is much more effective for long term health.
