🌱 How to Care for Rieger Begonia to Prevent Mealybugs?

💧 How to Water

Water every 4 days when the top of the soil feels dry to the touch. Always water directly at the base, never overhead — wet foliage encourages fungal diseases. Use room-temperature water and ensure the pot drains freely.

☀️ Lighting

Bright indirect light (5,000–15,000 lux) is ideal. Place near an east or north-facing window. Avoid direct sun, which scorches the delicate flowers and leaves, and avoid deep shade, which prevents blooming.

🪴 Ideal Soil

Use a well-draining, peat-based mix with pH 5.5–6.5. A blend of peat moss, perlite, and coarse sand works well. Never let the roots sit in waterlogged soil.
