🌱 How to Care for Bush Lily to Prevent Rust?

💧 How to Water

Allow the top half of the soil to dry between waterings. Reduce watering significantly during the autumn-winter rest period. Overwatering is the most common cause of problems with Clivia.

Thrives in bright indirect light. Avoid direct sunlight, which can scorch the leaves. A north-facing or shaded east/west window is ideal. Can tolerate lower light but may not bloom.

🪴 Ideal Soil

Use a well-draining potting mix. A blend of peat, perlite and bark works well. Clivia prefers to be slightly root-bound, so choose a snug pot with good drainage.
