Troubleshooting
Ludwigia glandulosa problems — and how to fix them
Ludwigia glandulosa (Ludwigia glandulosa) 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.
Stays green, no purple
Purple tones require high light and ample iron. Increase intensity and dose an iron supplement; without CO2 colour rarely peaks.
Stunted growth tips
This species is notoriously deficiency-sensitive; deformed new growth points to low CO2 or micronutrients. Add CO2 and complete trace dosing.
Leggy stretching
Long internodes mean insufficient light. Raise the fixture output or move stems higher in the water column.
Conversion melt
Emersed nursery plants often shed leaves when first submerged. Keep parameters stable until the submerged purple leaves develop.
