🌱 How to Care for Poppy Anemone to Prevent Pythium Root Rot?

💧 How to Water

Water 2-3 times a week during active growth and bloom, keeping the soil evenly moist but never waterlogged. Once flowering finishes and the leaves begin to yellow, cut back sharply and let the soil dry out almost completely -- the tuber needs a dry rest.

☀️ Lighting

Full sun suits it best, though a little afternoon shade helps in hot climates and can extend the bloom by keeping the plant from drying out too fast.

🪴 Ideal Soil

Plant tubers in light, porous, well-draining soil -- a mix of garden soil with sand and leaf mould, or peat, coir and perlite in containers -- with a slightly acidic to neutral pH around 6-7. Good drainage is non-negotiable; standing water quickly rots the tuber.
