Overview
Echinodorus horizontalis takes its name from holding its leaves nearly parallel to the ground at the ends of long stalks. The leaves are lance-shaped with a slightly heart-shaped base and medium green; young leaves may show reddish tones. Thanks to this posture, the plant spreads sideways rather than upward and shades the plants below it. It comes from the soft, slightly acidic waters of the Amazon basin.
Planting and Placement
The roots are buried with the crown left exposed. A nutrient-rich substrate or root tabs are essential. Because it spreads sideways, leave at least 20 cm of space around it; do not put small, shade-intolerant plants beneath it.
Care and Fertilization
- Light: Medium.
- CO₂: Not required, but it speeds up growth noticeably.
- Water: Prefers soft, slightly acidic water; it slows down in very hard water.
- Fertilizer: A root tab once a month; cut old outer leaves at the base.
