🌱 How to Care for Magnificent Anthurium to Prevent Pythium Root Rot?

💧 How to Water

Water when the top half of the potting mix feels dry, typically every 7-10 days. Never let the plant sit in soggy soil, as the thick roots rot quickly when oxygen-starved.

☀️ Lighting

Bright, indirect light is ideal. Direct sun scorches the velvety leaves, while too little light slows growth and dulls the leaf venation.

🪴 Ideal Soil

Use a light, well-aerated, organically rich mix (coco chips, orchid bark, perlite, charcoal) with a slightly acidic pH between 5.5 and 6.5.
