Overview
Red myriophyllum is a South Asian plant whose finely divided leaves are arranged in whorls along the stem and, under the right conditions, take on colors from red to burgundy. From a distance it looks like a soft red brush. Despite its beauty it is difficult: it needs strong light, regular CO₂, soft water and iron-rich fertilization. When these are lacking, the leaves turn brown and the stems become sparse. Since dirt and algae easily cling to its fine leaves, it needs clean water and good filtration.
Planting and Placement
- Plant the stems individually, 3 cm apart, 3 cm deep.
- Use it as a group in the background so that it becomes a color focal point among green plants.
Care and Fertilization
- Light: High.
- CO₂: Required.
- Water: Soft (GH 2–8), slightly acidic.
- Fertilizer: Iron and micronutrients should be dosed regularly.
- Trimming: Cut from the top; replant the healthy cut tips.
