California Polypody problems — and how to fix them
California Polypody (Polypodium californicum) 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.
Premature frond browning and dormancy
In gardens with hot, dry summers the fronds die back earlier than expected — this is normal summer dormancy, not a disease or watering failure. Simply reduce water and allow the plant to rest; new fronds will emerge in autumn with cooler temperatures and increased moisture.
Root rot in poorly drained winter soil
Although it tolerates winter wet in its native habitat, waterlogging in heavy clay soils causes rhizome rot, particularly in combination with cold temperatures. Improve drainage with grit or grow in raised beds; avoid clay-heavy soils.
