🌱 How to Care for Martens' Spikemoss to Prevent Fungus Gnats?

💧 How to Water

Water every 3–5 days with soft, lime-free water — rainwater or distilled is ideal. Keep the soil consistently moist but never waterlogged. Do not let the substrate dry out completely, as this causes rapid foliage decline.

☀️ Lighting

Place in low to medium indirect light — near a north or east-facing window is ideal. Avoid direct sunlight, which will scorch the delicate foliage. It tolerates low light better than most houseplants.

🪴 Ideal Soil

Use a peaty, well-draining mix — a blend of peat moss, perlite, and coarse sand works well. Slightly acidic pH of 5.0–6.0 is preferred. Shallow containers are fine due to its minimal root depth.
