Spring Cinquefoil problems — and how to fix them
Spring Cinquefoil (Potentilla neumanniana) 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 or clay soil
The most common failure mode; winter waterlogging kills the central crown. Plant in raised beds or scree conditions and improve drainage with abundant coarse grit before planting.
Vine weevil grub damage
Vine weevil larvae can sever roots in containers or on sandy borders, causing sudden wilting and plant death. Check roots if a plant wilts suddenly; use a biological nematode drench in late summer as a preventive measure.

Most spring cinquefoil issues are care-mismatch, not bad luck. Dial in the basics:
