Marie's Davallia problems — and how to fix them
Marie's Davallia (Davallia mariesii) 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.
Frond drop / apparent death in winter
This is normal deciduous behaviour. Davallia mariesii naturally drops fronds in late autumn and becomes dormant through winter, especially in cooler conditions. Keep rhizomes barely moist and do not discard the plant — new fronds will emerge in spring as temperatures rise.
Rhizome rot
Overwatering or excessive moisture during dormancy causes soft, blackened rhizomes. Water very sparingly in winter and ensure the growing medium drains freely. Cut out rotted sections and dust cuts with powdered sulphur or cinnamon to prevent spread.
Pale or stunted new fronds
Usually a sign of insufficient light or nutrient depletion after several years in the same medium. Move to a brighter position and apply a dilute balanced fertiliser during the growing season. Repot every 2–3 years to refresh the growing medium.
