🌱 How to Care for Paddle Plant to Prevent Gray Mold (Botrytis Blight)?

💧 How to Water

Water only when the top 5 cm of soil is completely dry. Use the soak-and-dry method, pouring water directly onto the soil and never on the leaves. Reduce watering significantly in winter.

☀️ Lighting

Provide at least 6 hours of bright light daily. Full sun outdoors brings out the best red leaf coloring. Indoors, place near a south or west-facing window. Avoid intense midday sun through glass which can scorch leaves.

🪴 Ideal Soil

Use a well-draining succulent or cactus mix. Amend with coarse sand, perlite, or pumice for extra drainage. A mix of equal parts potting soil, sand, and perlite works well. pH should be slightly acidic to neutral (6.1-7.3).
