🌱 How to Care for Cape Primrose to Prevent Aphids?

💧 How to Water

Water when the top layer of soil feels almost dry — every 7–14 days depending on season. Always use room-temperature water and avoid wetting the leaves. Bottom watering works well to prevent crown rot.

☀️ Lighting

Provide bright, indirect light — an east or west-facing windowsill is ideal. Avoid direct afternoon sun which scorches leaves. In winter, move to the brightest location available.

🪴 Ideal Soil

Use a well-draining, peat-free houseplant or African violet potting mix. Shallow, wide pots are preferred over deep containers to prevent waterlogging. Repot each spring into a slightly larger pot.
