🌱 How to Care for Cape Primrose to Prevent Broad Mites?

💧 How to Water

Water when the leaves begin to soften slightly or when the top 2 cm of the substrate are dry. Avoid overwatering — excess water causes root rot. Use room temperature water and avoid wetting the leaves or flowers.

☀️ Lighting

Position in an east or west-facing window to receive bright, indirect light. Avoid intense direct sun, which can scorch the leaves. In environments with low natural light, grow lights are very effective.

🪴 Ideal Soil

Use a light, well-draining, and organic-rich substrate, such as African violet potting mix or a peat and perlite blend. The ideal pH is between 5.5 and 6.5. Good drainage is essential to prevent root rot.
