🌱 How to Care for Hens and Chicks to Prevent Rust?

💧 How to Water

Water every 14 days or less — only when soil is completely dry. In winter, water once a month or not at all. Never allow water to pool at the base; soggy soil causes fatal root rot.

☀️ Lighting

Requires at least 6 hours of direct sunlight daily. Outdoors, plant in south or west-facing spots. Indoors, place at the brightest window available. Insufficient light causes elongated, pale rosettes.

🪴 Ideal Soil

Use gritty, fast-draining soil: a commercial cactus/succulent mix or blend standard potting soil with 50% coarse sand, perlite, or pumice. pH 6.0–7.5. Never use heavy clay or moisture-retaining mixes.
