🌱 How to Care for Floating Fern to Prevent Aphids?

💧 How to Water

As a purely aquatic plant, water is its living medium. Maintain a constant water level and perform regular partial water changes in your aquarium or container to prevent toxin buildup. Avoid strong currents that could submerge the plant.

☀️ Lighting

Requires bright light between 5,000 and 20,000 lux, with at least 10 hours of illumination per day. In indoor environments, use full-spectrum lighting. Yellowing leaves indicate insufficient light or nutrient deficiency.

🪴 Ideal Soil

No conventional substrate is used — the plant floats on the water surface. Prefers slightly acidic to neutral water (pH 6.0–7.5). Add liquid aquatic fertilizers moderately to supply micronutrients such as iron and nitrogen.
