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

💧 How to Water

Water at the base every 3 days during the growing season, keeping water off the leaves and tuber crown. Allow the top centimeter of soil to dry slightly between waterings. During dormancy, water just enough to prevent the substrate from drying out completely.

☀️ Lighting

Place in bright indirect light, away from direct sun which can scorch the velvety leaves. Ideal range is 10,000–25,000 lux. An east- or west-facing window with a sheer curtain works perfectly.

🪴 Ideal Soil

Use well-draining potting mix with a pH of 5.5–6.5. Combine a quality potting soil with perlite or coarse sand to ensure excellent drainage. Avoid dense, compacted mixes that retain excess moisture around the tuber.
