🌱 How to Care for Pearl Bells to Prevent Scale Insects?

💧 How to Water

Water thoroughly only when the top 2-3 cm of soil is completely dry, roughly every 2-3 weeks. Overwatering is the most common cause of root rot in this species, so always err on the side of underwatering.

☀️ Lighting

Provide bright light with 1-2 hours of gentle morning sun (south, east or west exposure). Avoid harsh direct summer sun, which can scorch the blue-grey foliage; more direct sun is tolerated from fall through early spring.

🪴 Ideal Soil

Use a fast-draining cactus/succulent mix enriched with organic matter -- a blend of peat, perlite and coarse sand works well. Terracotta pots help the roots stay aerated and dry out faster.
