π± How to Care for Zebra Plant to Prevent Gray Mold (Botrytis Blight)?
π§ How to Water
Water thoroughly but sparingly, about every 2-3 weeks. Always allow the soil to dry out completely between waterings. Reduce frequency in winter to once a month. Overwatering is the most common cause of death - when in doubt, wait longer.
βοΈ Lighting
Provide bright, indirect light. An east or west-facing window is ideal. Avoid direct midday sun which can scorch leaves and cause stress colors (red, purple, or brown hues). Can tolerate lower light but growth will be slower.
πͺ΄ Ideal Soil
Use well-draining cactus and succulent mix. Enhance drainage by adding extra perlite or coarse sand. The ideal mix contains part potting soil, part perlite, and part sand. Good drainage is essential to prevent root rot.
