🌱 How to Care for October Daphne to Prevent Leaf Spot?

💧 How to Water

Water deeply but infrequently — every 2-3 weeks in summer, reducing to once a month in winter. Always allow the soil to dry out completely before watering again. Never let the plant sit in waterlogged soil as this causes root rot.

☀️ Lighting

Provide bright, direct sunlight for at least 4-6 hours daily. Outdoors, full sun is ideal. Indoors, place near a south-facing window. Insufficient light causes elongated, weak stems and loss of the characteristic blue-green leaf colour.

🪴 Ideal Soil

Use a gritty, well-draining succulent or cactus mix. Add perlite or coarse sand to improve drainage. Avoid heavy clay soils that retain moisture, as Sedum sieboldii is very sensitive to wet roots.
