🌱 How to Care for Red-Edge Peperomia to Prevent Pythium Root Rot?

💧 How to Water

Water every 7-10 days in spring and summer when the top inch of soil feels dry. Reduce to every 14-20 days in winter. Always empty the saucer after watering to prevent root rot — this is the most common cause of plant death in peperomias.

☀️ Lighting

Place in bright, indirect light near an east or north-facing window. It can tolerate lower light but the vibrant leaf variegation will be less pronounced. Avoid direct sunlight, which can scorch the leaves and fade the colors.

🪴 Ideal Soil

Use a light, well-draining potting mix — a blend of standard potting soil and perlite or coarse sand (2:1 ratio) works perfectly. Ensure the pot has drainage holes. Target soil pH of 6.0-7.0.
