Troubleshooting
Limnophila aromatica problems — and how to fix them
Limnophila aromatica (Limnophila aromatica) 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.
Green instead of red/purple colour
Insufficient light, low iron or no CO2. Raise light and CO2 and dose iron to bring out the signature purple undersides.
Leggy, stretched stems
Low light causes long internodes. Increase intensity, trim, and replant tops for a denser stand.
Melting after transition
Emersed-grown plants often shed leaves when first submerged. Keep parameters stable; new submerged growth will adapt within a few weeks.
Wilting of emersed culinary plants
Caused by the rootzone drying out. Keep soil constantly saturated and humidity high, as in a paddy.
