Troubleshooting
Ludwigia arcuata problems — and how to fix them
Ludwigia arcuata (Ludwigia arcuata) 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.
Loss of red colour
Reverts to green under inadequate light or low iron. Raise light intensity and add an iron-rich fertiliser.
Leggy, sparse stems
Stretching indicates too little light or no CO2. Increase lighting and add CO2 for the tight, bushy form.
Slow, stunted growth
This species is sensitive to nutrient gaps; stunted tips signal a micronutrient or CO2 shortfall. Improve dosing and flow.
Emersed-to-submersed melt
Newly purchased emersed plants often drop leaves during conversion. Hold conditions steady until submerged needle leaves form.
