Troubleshooting
Overlooked Lagenandra problems — and how to fix them
Overlooked Lagenandra (Lagenandra praetermissa) 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
Switching between submersed and emersed conditions causes temporary leaf drop; new growth adapted to the new environment will emerge within weeks.
Root rot
Overwatering without adequate drainage in terrarium culture invites rot; ensure free-draining substrate.
Brown leaf edges
Usually caused by low humidity or hard water; increase misting frequency and use soft or RO water.
Slow growth
Normal for the genus; supplement CO2 in aquatic setups and provide adequate micronutrients to encourage steady growth.
Spider mites
Occur in dry emersed conditions; increase humidity and rinse leaves with water to dislodge.
