Rinse roots under lukewarm running water to remove all soil.
Aggressive pruning
Cut away ALL affected roots without hesitation. Its better to over-prune than leave infected tissue.
Peroxide treatment
Spray or dip roots in 3% hydrogen peroxide solution. This kills pathogens and oxygenates tissue.
Quick dry
Pat roots with paper towels and let air dry for 30-60 minutes.
Fast repot
Repot in completely dry, fresh potting mix. Do not water for 3-5 days.
Stress reduction
Place in bright indirect light, away from direct sun. Reduce watering frequency significantly.
Organic Treatment
Remove and assess
Carefully remove the plant from its pot and gently wash away all soil from the roots. Assess the extent of root damage.
Prune affected roots
Using sterile scissors, cut away all soft, mushy, brown, or black roots. Cut back to healthy white tissue.
Apply cinnamon
Dust all cut surfaces generously with cinnamon powder to prevent fungal regrowth.
Prepare chamomile soak
Brew strong chamomile tea and let it cool. Soak the remaining roots for 15-20 minutes.
Air dry roots

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.
