🌱 How to Care for Fiber optic grass to Prevent Fungus Gnats?

💧 How to Water

Keep the soil fully saturated at all times; this plant cannot be overwatered in the usual sense and is happiest sitting in a saucer or dish with 1-2 cm of standing water. Never let the pot dry out -- even a short dry spell will brown the delicate stems.

☀️ Lighting

Give it full sun to bright, filtered light. It tolerates partial shade, but growth turns thinner and lankier the less light it gets.

🪴 Ideal Soil

Use a moisture-retentive, organic-rich or peat-based mix -- a blend made for bog or marginal aquatic plants is ideal. For water-garden use, aquatic compost topped with washed gravel works well.
