Small Scabious problems — and how to fix them
Small Scabious (Scabiosa columbaria) 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 in wet winter soil
Heavy, poorly drained or clay soil kills crowns over winter. Grow in raised beds or sharply drained ground, and avoid mulching directly over the crown. Plants on well-drained chalk or gritty soil are rarely affected.
Short-lived clumps
Individual plants can exhaust themselves after 3–5 years, especially without division. Divide clumps every 2–3 years in spring, or allow self-seeding to maintain the colony; replant vigorous outer divisions and discard the woody centre.
