Troubleshooting
Anouk French lavender problems — and how to fix them
Anouk French lavender (Lavandula stoechas 'Anouk') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Cold damage and winter losses
'Anouk' is less hardy than English lavenders and can be killed by prolonged frost below about -5°C or by cold, wet soil. In UK zones below H4, overwinter container plants under glass or in a frost-free porch; mulch in-ground plants with dry gravel.
Botrytis on flower heads
The dense, enclosed flower structures trap moisture and are prone to grey mould in wet springs. Dead-head promptly after flowering, improve airflow, and avoid overhead watering. Copper-based fungicide can be applied as a preventative in very wet seasons.
Short lifespan without pruning
'Anouk' benefits from two prunings per year: a light trim after the first flush to encourage reblooming, and a harder cut by one-third in early autumn. Without pruning, plants become open and woody within 2–3 years and flowering declines significantly.
