Troubleshooting
Ludwigia palustris problems — and how to fix them
Ludwigia palustris (Ludwigia palustris) 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.
Lower stems go bare
Caused by insufficient light reaching the base or shading from taller plants. Trim tops and replant them, and thin dense growth so light penetrates.
Green instead of red
Red and bronze tones only develop under high light and good iron levels. Increase intensity and dose an iron-rich fertiliser.
Melt after planting
Submersed-grown plants may shed emersed-form leaves when conditions change. Keep parameters stable; new submerged leaves emerge within a couple of weeks.
Stunted, twisted tips
Usually a micronutrient or CO2 deficiency. Add CO2 or improve flow and ensure complete trace-element dosing.
