Troubleshooting
Meebold's Lagenandra problems — and how to fix them
Meebold's Lagenandra (Lagenandra meeboldii) 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.
Leaf melt on transition
Rapid shifts between submersed and emersed cultivation cause leaves to decay ('melt'). Always transition gradually over several weeks, adjusting water levels slowly to let the plant acclimate.
Algae on leaves
The slow growth rate and broad leaf surface make it prone to algae colonisation in aquariums. Reduce lighting duration, add fast-growing floating plants to compete, and introduce algae-eating fauna such as Otocinclus.
Rhizome rot
Burying the rhizome in substrate rather than anchoring it at the surface causes rot. Pin the rhizome down with a small stone or plant it so the crown remains at or just above substrate level.
