Troubleshooting
King Sundew problems — and how to fix them
King Sundew (Drosera regia) 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.
Mineral burn from tap water
Using tap or filtered (not RO/distilled) water makes leaf tips brown and the plant decline. Switch to rainwater, distilled or reverse-osmosis water only.
No dew / green floppy leaves
Almost always too little light. Move to direct sun or a strong grow light; healthy leaves are tinged red and beaded with mucilage.
Root rot in stagnant warmth
King sundew has a sensitive root system; constant warm, airless, soggy conditions invite rot. Give airflow and let it cool in winter rather than baking it year-round.
Skipped winter dormancy
This species benefits from a cooler (around 5-12°C), drier winter rest. Kept hot all year it weakens over time and may collapse.
