Troubleshooting
Provence Lavender problems — and how to fix them
Provence Lavender (Lavandula × intermedia 'Provence') 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.
Root rot in heavy soil
Wet clay or poor drainage rots the roots. Plant in raised, gritty beds and water only when the soil is dry.
Woody, leggy growth
Skipping the annual trim leads to a bare, splayed base. Prune after flowering within green growth, avoiding old leafless wood.
Fungal dieback in damp climates
Phytophthora and botrytis appear in still, wet conditions. Improve airflow, avoid overhead watering, and keep mulch off the crown.
Sparse flowering in shade
Too little sun reduces both bloom count and fragrance. Relocate to the sunniest, most open spot available.
