Comb-Leaved Santolina problems — and how to fix them
Comb-Leaved Santolina (Santolina pectinata) 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
The most common cause of death; occurs when plants sit in waterlogged or poorly drained soil, particularly over winter. Improve drainage radically — add grit, raise the bed, or grow in containers with drainage holes — rather than reducing watering alone.
Woody dieback and bare centre
Established plants become progressively woodier if not pruned; cut back by about one-third immediately after flowering each year to maintain a dense, compact mound and delay the need for replacement.
