Water parameters
Overview
Ludwigia inclinata 'Cuba' is a rare ludwigia form whose leaves are arranged not in pairs but in whorls (verticils) along the stem. Under the right conditions the narrow, pointed leaves turn from orange to deep red, and from a distance the plant looks like a red bush. This look can only be achieved with careful care: soft, acidic water, strong light, constant CO₂ and regular iron supplementation are essential. When these conditions are not met, the leaves become smaller and the plant declines.
Planting and Placement
- Stems are planted singly or in groups of 2–3, 3–4 cm apart.
- It is placed in the background, in the area that gets the best light.
- A nutrient-rich active substrate that softens the water makes things much easier.
Care and Fertilization
- Light: High.
- CO₂: Required.
- Water: Very soft (GH 1–6), slightly acidic water.
- Fertilizer: Iron, potassium and micronutrients should be dosed regularly; if nitrate runs out completely, the leaves become stunted.
- Trimming: Cut from the top; healthy cut tops are replanted.
