Troubleshooting
Ceratopteris cornuta problems — and how to fix them
Ceratopteris cornuta (Ceratopteris cornuta) 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 rot from wet leaves
Strong surface splashing keeps the floating fronds wet and triggers rot. Reduce surface agitation and skim or remove decaying leaves promptly.
Rapid surface takeover
Floating rosettes and plantlets quickly blanket the surface, blocking light below. Thin regularly to keep gas exchange and light to lower plants.
Yellowing fronds
Pale or yellow leaves indicate nutrient or iron shortfall. Dose a complete liquid fertiliser with trace iron.
Tangled trailing roots
Long roots can clog filter intakes and entangle small fish. Trim the root mass occasionally to keep it manageable.
