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 Fynbos Aloe to Prevent Rust?

💧 How to Water

Water deeply then let the soil dry out completely before watering again — roughly every 10-14 days in active growth, much less in winter dormancy. Overwatering quickly causes root and crown rot.

☀️ Lighting

Provide full sun to semi-shade outdoors, or the brightest spot available indoors (a south-facing window). It does not tolerate low light, which causes weak, stretched growth.

🪴 Ideal Soil

Use a sandy, gritty, fast-draining mix — a cactus/succulent blend with extra perlite or coarse sand. Avoid rich, moisture-retentive soils.
