Fennel-Leaved Sea Lavender problems — and how to fix them
Fennel-Leaved Sea Lavender (Limonium ferulaceum) 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.
Root rot in heavy or wet soils
Overwatering or poorly drained soil quickly causes root and crown rot; ensure sharply drained growing conditions and avoid any soil that holds standing water, especially in winter.
Grey mould (Botrytis cinerea)
In wet seasons or high-humidity environments, Botrytis can colonise spent flowers and soft foliage; improve air circulation and remove dying flower stems promptly after blooming.
