Troubleshooting
Alpine Cinquefoil problems — and how to fix them
Alpine Cinquefoil (Potentilla crantzii) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Sparse flowering
Insufficient sun is the most common cause. P. crantzii flowers best in an open, sunny position. Also check that the plant is not rootbound in a container (repot in spring) or grown in overly rich soil, which promotes foliage over flowers.
Root rot in winter wet
While extremely frost-hardy, P. crantzii is intolerant of prolonged waterlogging, particularly in winter. Plant in raised beds, rock garden pockets, or gritty troughs to ensure free drainage year-round. In heavy-rainfall climates, a winter pane of glass over potted specimens is beneficial.
Crown die-back
In poorly drained or very humid conditions, the centre of old clumps can die back. Divide clumps every 3–4 years in spring, discarding the woody, unproductive centre and replanting vigorous outer sections. This also maintains flowering vigour.
