Organic Treatment

Mechanical Removal

Remove all infected leaves and parts with clean shears. Dispose in trash (not compost). Clean tools with 70% alcohol between cuts.

Sulfur Application

Apply sulfur fungicide to all leaf surfaces, especially undersides. Do this in the morning for quick drying. Do not apply above 30°C (86°F).

Watering Adjustment

Switch to drip irrigation or water directly at soil level. If using overhead watering, do so between 5-10 AM.

Improve Circulation

Prune dense branches to increase airflow. Maintain proper spacing between plants.

Monitoring

Inspect weekly. Reapply sulfur every 7-10 days for 3 weeks. Continue for 2 weeks after last symptom.

🌱 How to Care for Globe Houseleek to Prevent Rust?

💧 How to Water

Use the soak-and-dry method: water deeply, then wait until the soil is completely dry before watering again. In winter, reduce to once a month or less. Overwatering is the leading cause of death.

☀️ Lighting

Provide at least 6 hours of direct sunlight daily. A south- or west-facing spot outdoors or a bright windowsill indoors is ideal. Insufficient light causes etiolation and weakens the plant.

🪴 Ideal Soil

Plant in a gritty, well-draining mix — 50% coarse perlite or grit with 50% succulent potting soil. Never use heavy, moisture-retaining soils. Terracotta pots help wick away excess moisture.
