Best Growing Conditions for Miscanthus Sinensis

🌱 Prefers moist, well-drained soil
🌱 Tolerates clay, loam, and sandy soils

Planting Miscanthus

1️⃣ Choose a sunny, open position
2️⃣ Space plants 75–100cm apart to allow for mature clump development
3️⃣ Dig in organic matter to improve structure and water retention
4️⃣ Plant at the same depth as the pot and water in well
5️⃣ Mulch in spring to retain moisture and suppress weeds


Watering & Feeding

Watering Tips

💧 Water regularly until established (first 12–18 months)
💧 Once mature, drought tolerant but benefits from watering in hot spells

Feeding Tips

🌿 Apply a slow-release fertiliser in spring if growth seems slow
🌿 Avoid overfeeding – Miscanthus performs well with minimal inputs


Pruning & Maintenance

✂️ In late winter to early spring, cut back dead foliage to 10–15cm before new shoots emerge
✂️ Leave seed heads standing over winter for texture and wildlife interest
✂️ Divide mature clumps every 4–5 years in spring to maintain vigour

📌 Tip: Wear gloves – the dry leaves can be sharp when cutting back.
