🌱 How to Care for Anemone to Prevent Gray Mold (Botrytis Blight)?

💧 How to Water

Keep the soil evenly moist during growth and flowering, watering roughly every 4-6 days in dry weather and letting the top layer dry slightly in between. Water at the base, not over the leaves, to limit mildew and grey mould. Tubers rot quickly in waterlogged ground, so cut back watering once the foliage of spring anemones yellows and the plant goes dormant.

☀️ Lighting

Most anemones flower best with at least 6 hours of sun a day. In hot climates give them light afternoon shade; Japanese anemones and Grecian windflowers also do well in dappled shade under trees. Too little light gives long, weak stems and few flowers.

🪴 Ideal Soil

Use loose, fertile soil rich in organic matter that drains freely: dig in compost or well-rotted manure before planting and add grit or sand to heavy clay, or plant in raised beds. In pots, a peat-free multipurpose compost with extra grit works well. Good drainage matters more than soil type.
