Pocket Botanist
Check these first
- Inspect the undersides of the leaves for orange dust or raised bumps.
- Check if the plant is crowded by other shrubs.
- Look for signs of poor drainage around the base.
Likely causes
Rust fungus
Most likelyHow to tell: You will see small, raised orange or brown pustules on the undersides of the leaves. The foliage may eventually yellow and drop prematurely.
What to do: Prune away the most heavily infected branches to improve airflow. Clean your shears with rubbing alcohol between cuts to avoid spreading spores. Avoid overhead watering to keep the leaves dry.
Leaf spot disease
PossibleHow to tell: These appear as dark, irregular patches that might have a yellow halo around them. They usually develop after periods of heavy rain.
What to do: Rake up and dispose of any fallen leaves beneath the shrub to remove the source of infection. Apply a copper based fungicide if the infection is widespread. Ensure the plant is in a sunny spot with good air circulation.

When to worry
It is serious if the spotting covers more than half of the foliage or causes total defoliation. A few spots here and there are normal in a wet spring.
Stopping it coming back
Space your shrubs properly to allow wind to dry the foliage quickly after rain. Water at the base of the plant rather than spraying the leaves.
