Bellflower Codonopsis problems — and how to fix them
Bellflower Codonopsis (Codonopsis vinciflora) 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.
Taproot rot
The fleshy taproot is very susceptible to rot if the soil stays wet over winter; plant in raised beds or incorporate grit to ensure drainage, and consider lifting the root in very cold, wet climates.
Slugs and snails
Emerging spring shoots from the taproot are a prime target for slugs; protect with a copper barrier or wildlife-friendly slug pellets (ferric phosphate) as soon as shoots appear in late April or May.
