Viper's Bugloss problems — and how to fix them
Viper's Bugloss (Echium vulgare) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Powdery mildew
Warm, humid conditions with poor air circulation promote powdery mildew on leaves; plant in an open, sunny position with good air flow and avoid overhead watering to reduce risk.
Slugs on seedlings
Young basal rosettes are vulnerable to slug damage, especially in autumn and wet springs; apply organic slug deterrent or use copper collars around young plants, as the stiff bristles of older leaves provide natural defence.
