Canary Island Sea Lavender problems — and how to fix them
Canary Island Sea Lavender (Limonium pectinatum) 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 winter
The most common cause of loss when grown under glass; wet compost combined with low winter temperatures is rapidly fatal. Keep the pot on the dry side from October through February.
Red spider mite
Thrives in warm, dry greenhouse conditions; look for fine webbing and pale stippling on the stiff leaves. Raise humidity locally or use a predatory mite (Phytoseiulus persimilis) as a biological control.
