🌱 How to Care for Evergold Sedge to Prevent Fungus Gnats?

💧 How to Water

Water every 5-7 days during warmer periods, allowing the top third of the substrate to dry slightly between waterings. In winter, reduce watering to every 10-14 days. Avoid prolonged waterlogging, which can cause root rot. In pots, ensure that excess water drains freely from the bottom.

☀️ Lighting

Prefers partial shade to filtered sun—ideal near north or east-facing windows, or in outdoor spaces with morning light. Avoid intense direct sun, especially in summer, as it can burn the delicate leaves. In cooler, cloudier climates, it tolerates more direct sun without damage.

🪴 Ideal Soil

Plant in a well-drained, fertile substrate rich in organic matter. The ideal pH is between 5.5 and 7.0 (slightly acidic to neutral). It can be grown in clay, loamy, or sandy soils, provided that excess water does not stagnate at the roots. Mix perlite or coarse sand into the substrate to improve drainage in pots.
