🌱 How to Care for Zebra Plant to Prevent Anthracnose?

💧 How to Water

Water when the top 2-3 inches of soil feel dry. Keep soil consistently moist but never soggy to avoid root rot. Reduce watering significantly in winter. Use room temperature water, preferably rainwater or filtered water as this plant is sensitive to lime and minerals.

☀️ Lighting

Provide bright, indirect light - ideally near a south-facing window with filtered light. Morning or evening sun is tolerated, but avoid harsh midday direct sunlight which will scorch the leaves. Not tolerant of low light conditions.

🪴 Ideal Soil

Use a well-draining, slightly acidic potting mix. A blend of 50% potting soil, 30% perlite, and 20% orchid bark works well. Can also use a mixture of coco coir, perlite, and organic matter. The soil should retain some moisture while allowing excess water to drain freely.
