Quick Fixes
Remove Plant
Immediately remove entire infected plant with roots. Dispose in sealed trash (DO NOT compost).
Disinfect Area
Spray area with diluted bleach solution (1:10). Allow to dry.
Apply Biofungicide
If available, immediately apply Mycostop or Trichoderma to affected soil.
Isolate Area
DO NOT plant anything in same area for at least 6 months. Fusarium remains in soil.
Organic Treatment
Immediate Removal
Completely remove infected plant including all roots. Do not compost - burn or dispose in sealed trash.
Tool Disinfection
Clean all tools with 10% bleach solution for 5 minutes. Allow to dry completely in sun.
Soil Solarization
Cover affected area with clear plastic for 4-6 weeks in summer. Heat eliminates pathogens.
pH Correction
Test soil pH. If acidic, add lime to raise pH to 7.0-7.2. Fusarium prefers acidic soils.
Biological Inoculation
Add well-cured compost rich in Trichoderma or apply biological product (Mycostop). Wait 2 weeks before replanting.
Replant with Resistant Varieties
Use ONLY Fusarium-resistant varieties. Check certification. Maintain good drainage.

ðą How to Care for Century Plant to Prevent Fusarium Wilt?
ð§ How to Water
Water only when the soil is completely dry â typically every 14 days in the growing season and once a month in winter. Never allow water to pool in the saucer. Overwatering causes crown rot, the number one killer of agave plants.
âïļ Lighting
Requires full sun â at least 6 to 8 hours of direct sunlight daily. Tolerates partial shade but growth will be slower and leaf coloration less vibrant. Indoors, place near south- or west-facing windows with maximum light exposure.
ðŠī Ideal Soil
Use cactus and succulent potting mix with excellent drainage. Combine coarse sand or perlite (50%) with potting soil (50%). Pots must have drainage holes. Ideal pH between 6.0 and 8.0. Avoid clay-heavy or compacted soils that retain moisture.
