Quick Fixes

Immediate removal

Remove and completely destroy all infected plants. Burn or bag and dispose in trash.

Apply fungicide

Apply systemic fungicide (SDHI or DMI) to neighboring healthy plants preventively.

Reduce moisture

Stop all overhead watering. Use drip only. Improve ventilation/drainage.

Isolate area

Create buffer zone by removing plants within 20-inch radius of infection.

Intensive monitoring

Inspect remaining plants 2x daily for 14 days.

🌿

Organic Treatment

Remove infected plants

Carefully remove entire plant without spreading sclerotia. Burn or bury deeply (24+ inches). Do not compost.

Apply biocontrol

Apply Coniothyrium minitans to soil per instructions. This fungus parasitizes Sclerotinia sclerotia.

Improve circulation

Thin adjacent plants to improve airflow. Space plants 12-18 inches apart.

Adjust irrigation

Switch to drip irrigation. Water early morning. Avoid wetting foliage.

Soil solarization

If possible, cover soil with clear plastic for 4-6 weeks in summer (kills sclerotia).

Monitoring

Inspect plants daily for 3 weeks. Remove any new infection immediately.

🌱 How to Care for Garlic Chives to Prevent White Mold?

💧 How to Water

Water every 4 days when the top inch of soil feels slightly dry. Avoid waterlogging — soggy soil leads to root rot. Water at the base of the plant in the morning so foliage can dry during the day, reducing fungal disease risk.

☀️ Lighting

Garlic chives thrive in full sun with at least 6 hours of direct sunlight per day. Indoors, place near a south-facing window or supplement with LED grow lights. Partial shade is tolerated but reduces growth and harvest yield.

🪴 Ideal Soil

Prefers well-draining, loamy to sandy-loam soil rich in organic matter. Ideal pH 6.5–7.5. Amend with compost before planting to improve fertility and drainage. Avoid heavy clay soils that retain excess moisture.
