🌱 How to Care for Green Velvet Alocasia to Prevent Bacterial Leaf Spot?

💧 How to Water

Water every 7–10 days during the growing season, allowing the top 1–2 inches of soil to dry slightly between waterings. Reduce frequency in winter when the plant may go dormant. Always use well-draining pots and never let the roots sit in standing water to prevent root rot.

☀️ Lighting

Place in a spot with bright, indirect light — near a north or east-facing window is ideal. Avoid direct sunlight, which can scorch the velvety leaves. A minimum of 2,000 lux is needed for healthy growth; supplement with a grow light if natural light is insufficient.

🪴 Ideal Soil

Use a well-draining mix of peat or coco coir, perlite, and a small amount of compost. A ratio of 60% peat, 30% perlite, and 10% compost works well. Ensure the pot has drainage holes. The soil should retain some moisture but never become waterlogged.
