Quick Fixes
Immediate removal
Remove and completely destroy all infected plants. Burn or bag and dispose in trash.
Apply fungicide

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 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.

ð§ How to Water
Water every 10â14 days during the growing season, allowing the soil to dry out completely between waterings. In winter, reduce to once a month. Never let the plant sit in standing water as this causes root rot.
âïļ Lighting
Place in a bright spot with at least 4â6 hours of light per day. A south- or west-facing window is ideal indoors. Outdoors, partial sun to full sun works well. Avoid deep shade, which causes leggy growth.
ðŠī Ideal Soil
Use a well-draining cactus or succulent mix. Amend standard potting soil with 50% perlite or coarse sand for best drainage. A slightly acidic to neutral pH (6.0â7.0) is preferred.
