Troubleshooting
Spanish Lavender problems — and how to fix them
Spanish Lavender (Lavandula stoechas) 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 overwatering
The single most common cause of decline. Wet, heavy, or poorly drained soil rots the roots; plant in grit and water sparingly.
Woody, leggy base
Old plants go bare and sparse at the center. Prune lightly after each flush, never cutting back into old leafless wood, which rarely regenerates.
Winter loss in cold, wet climates
Less hardy than English lavender. In zones below 8 or wet UK winters, grow in containers and overwinter under cover.
Poor flowering and weak scent
Caused by too little sun or too-rich soil. Move to full sun and stop feeding to restore blooms and aromatic oils.
