Care Guide

💧 Water Every 7 days
Suggested frequency: Every 7 days
☀️ Light Full sun

Southern naiad comes from habitats with abundant sunlight, such as the shallow margins of ponds and lakes. It prefers full sun but can also tolerate partial sun.

Ideal: Full sun
🌡️ Temperature 10–37.8°C

Southern naiad can tolerate a wide range of temperatures, but its distribution may still be restricted by different combinations of moisture and heat. It does best in warm summer climates with sufficient rainfall or watering. Prolonged stretches of cloudy, rainy weather, as well as extended high temperatures, can increase the chance of Southern naiad dying. In winter, appropriate protection from cold can improve the plant's survival rate.

Ideal temperature: 10–37.8°C

✂️ Pruning

The Southern naiad, characterized by its thin, grass-like leaves, thrives in aquatic environments. To encourage growth and control its spread, prune it in early spring by removing any damaged foliage. Regular pruning helps prevent overgrowth and maintains water quality. Always use clean, sharp tools to minimize the risk of disease.
