Troubleshooting
Polynesian Davallia problems — and how to fix them
Polynesian Davallia (Davallia solida) 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.
Shrivelled or rotting rhizomes
Rhizomes shrivel when the plant is severely under-watered, or rot when constantly wet. Water thoroughly when the medium is partially dry, never leave in standing water, and ensure the coarse growing medium drains freely. Rotted sections should be cut away cleanly.
Frond drop in winter
Davallia solida may partially or fully lose its fronds in cool winter conditions — this is semi-dormancy, not death. Keep rhizomes barely moist, maintain temperatures above 15 °C, and new fronds will emerge in spring as light and warmth return.
Scale insects
Hard, waxy brown scales cluster on frond undersides and along rhizomes, causing yellowing and sticky residue. Remove manually with a cotton swab dipped in isopropyl alcohol and follow up with repeated neem oil applications every 7–10 days.
