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 Cheddar Pink to Prevent Rust?

💧 How to Water

Water deeply but infrequently, letting the top of the soil dry out between waterings. Established plants are quite drought tolerant; the biggest threat is overwatering, which leads to crown and root rot.

☀️ Lighting

Needs full sun — at least 6 hours of direct light a day — to keep its mat compact and flower heavily. Tolerates light afternoon shade in hot climates but gets leggy in shade.

🪴 Ideal Soil

Plant in loose, sharply-draining, neutral to alkaline soil (chalky or limy soils are ideal). Heavy, wet clay is the main cause of failure; amend with grit or sand if drainage is poor.
