When to worry
If the spots cover most of the plant and leaves start to shrivel, you need to act quickly. A few small spots are manageable with better airflow.
Stopping it coming back
Keep your Heath in a spot with good air movement and avoid overhead watering that keeps leaves wet for hours.

Questions people ask
- Is powdery mildew harmful?
- Yes, it can weaken the plant and prevent it from photosynthesizing properly. It is best to treat it as soon as you notice the white patches.
- Should I use a fungicide?
- Usually, improving air circulation and wiping the leaves is enough. If it persists, a mild horticultural oil or neem oil can help.
