Troubleshooting
Canary Island Lavender problems — and how to fix them
Canary Island Lavender (Lavandula canariensis) 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.
Frost damage
Stems blacken and die back at temperatures below 0°C (32°F). Bring container-grown plants into a frost-free greenhouse or conservatory before the first autumn frost.
Root rot from overwatering
The most common cultural problem; affected plants wilt despite moist compost. Repot into fresh gritty compost, removing all blackened roots, and reduce watering frequency.
