Troubleshooting
English Lavender problems — and how to fix them
English Lavender (Lavandula angustifolia 'Hidcote') 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 from wet soil
The leading cause of failure; lavender needs sharp drainage and dry roots, so avoid overwatering and heavy, water-holding ground, especially in winter.
Woody, bare base
Skipping the annual trim leaves an open, leggy plant; shear lightly after flowering, but never cut back into old leafless wood, which rarely reshoots.
Poor flowering in shade
Too little sun gives weak, floppy growth and few blooms; site it in the sunniest, most open position available.
Fungal disease in humidity
Damp, crowded plantings develop dieback and fungal issues; space plants for airflow and avoid overhead watering.
