🌱 How to Care for Soft Water Fern to Prevent Aphids?

💧 How to Water

Water every 7 days, keeping the soil evenly moist at all times. Blechnum minus is highly sensitive to drought — never allow the soil to dry out completely. Check moisture at the top inch of soil before watering.

☀️ Lighting

Place in full to partial shade — less than 500–2000 lux. Avoid any direct sunlight, which scorches the fronds. A north-facing spot indoors or under a tree canopy outdoors is ideal.

🪴 Ideal Soil

Use a peaty, moisture-retentive, slightly acidic soil (pH 5.5–6.5). Adding perlite or coarse sand improves drainage while retaining sufficient moisture. Avoid heavy clay or compacted soils.
