🌱 How to Care for Velvet Elephant Ear to Prevent Powdery Mildew?

💧 How to Water

Water deeply but infrequently, allowing the soil to dry out completely between waterings. In winter, reduce watering to once a month or less. Always err on the side of underwatering — this plant handles drought far better than soggy roots.

☀️ Lighting

Provide bright, direct sunlight for best growth. A south-facing window or full outdoor sun is ideal. The velvety hairs on the leaves act as natural sun protection, so this plant can handle intense light.

🪴 Ideal Soil

Use a very well-draining succulent or cactus mix. Add extra perlite or coarse sand to improve drainage. The soil should never stay wet for extended periods.
