🌱 How to Care for Nardoo to Prevent Mealybugs?

💧 How to Water

Keep the soil or substrate constantly moist without stagnant waterlogging—Marsilea mutica can also be grown partially or fully submerged in shallow water (up to a few inches deep). Avoid letting the substrate dry out completely between waterings, as this stresses the plant.

☀️ Lighting

Prefers direct sunlight to partial shade (from 2 to over 6 hours of direct sun per day). For indoor or aquarium cultivation, use strong full-spectrum lighting for 12-16 hours daily to maintain leaf color and healthy growth.

🪴 Ideal Soil

Use a substrate rich in organic matter that retains moisture but does not become waterlogged—a specific mix for aquatic plants, heavy clay-humus soil, or aquarium substrate with sand/fine gravel. Ideal pH is between 6.0 and 7.0.
