Troubleshooting
Leathery Polypody problems — and how to fix them
Leathery Polypody (Polypodium scouleri) 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.
Rhizome rot
Overwatering, especially during summer semi-dormancy, causes the thick rhizome to rot from the base. Reduce watering in summer and ensure the pot has ample drainage holes.
Frond die-back in summer
Natural semi-dormancy can cause frond yellowing in warm, dry summers. Reduce watering, keep cool, and expect new growth to flush in autumn and winter.
Spider mites
Dry indoor air encourages spider mites on the undersides of fronds. Rinse fronds with cool water regularly and increase humidity slightly; treat infestations with insecticidal soap.
