Troubleshooting
Kerala Lagenandra problems — and how to fix them
Kerala Lagenandra (Lagenandra keralensis) 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.
Wilting and desiccation
Leaf collapse in emersed setups is usually caused by insufficient humidity or substrate drying out briefly. Improve enclosure sealing and ensure consistent substrate moisture.
Rhizome rot
Overly deep planting or anaerobic substrate causes the rhizome to rot. Plant shallowly with the rhizome just at the substrate surface.
Crypt-melt-like leaf die-back
Environmental changes trigger leaf collapse similar to crypt melt in Cryptocoryne. Stable water parameters and temperature prevent this; new leaves emerge from healthy rhizomes.
Pest attack (mites, aphids)
Emersed leaves in a humid vivarium can attract spider mites or fungus gnats. Inspect new plants carefully before introduction and treat with a mild insecticidal soap if needed.
Stunted or absent new growth
Low temperature below 22°C significantly slows this tropical species. Ensure consistent warmth, particularly at root level.
