Broad-Leaved Sea Lavender problems — and how to fix them
Broad-Leaved Sea Lavender (Limonium platyphyllum) 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.
Crown rot
The most common cause of death in heavy or poorly drained soils; roots decay rapidly in wet conditions, especially over winter. Always plant on a slope or raised bed and improve drainage with grit.
Powdery mildew
Can develop on foliage in humid, still conditions with low air movement; improve spacing and siting in open, breezy positions rather than relying on fungicide sprays.
