Check these first
- Check if the white spots can be wiped off with your finger.
- Observe if the plant is in a very humid or stagnant area.
- Look for signs of overcrowding around the base of the plant.
Likely causes
Powdery Mildew
Most likelyHow to tell: A white, powdery substance appears on the surface of the leaves, often looking like someone dusted them with flour.
What to do: Improve air circulation by thinning out crowded branches. Apply a fungicide labeled for powdery mildew or a mixture of 1 tablespoon of baking soda in a gallon of water to the leaves.
Poor Airflow
PossibleHow to tell: The spots appear primarily on leaves in the center of the plant where air does not move freely.
What to do: Prune away some of the inner branches to allow air to reach the center of the shrub. Ensure the plant is not crowded by other nearby plants.

When to worry
Powdery mildew is rarely fatal, but it can make the plant look unsightly and weaken it if left untreated for a long time.
Stopping it coming back
Water at the base of the plant rather than overhead to keep the leaves dry, and ensure the shrub has plenty of space for air to circulate.
