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.

🌱 How to Care for Dragon Scale Alocasia to Prevent Fusarium Wilt?

💧 How to Water

Water every 7 days, checking that the top third of the soil feels dry before watering again. Alocasia longiloba is highly water-sensitive and prone to root rot if left in soggy soil. Use filtered or room-temperature water that has sat for 24 hours to reduce chlorine. Reduce watering frequency in winter when growth slows.

☀️ Lighting

Thrives in bright indirect light, ideally between 2,000 and 10,000 lux. Avoid direct sunlight, which scorches the distinctive leaves, and deep shade, which causes slow growth and loss of the silvery venation pattern. Positioning about 1 metre from an east- or west-facing window is ideal.

🪴 Ideal Soil

Use a lightweight, well-draining, airy aroid mix: combine orchid bark, perlite, and coco coir in equal parts. The ideal soil pH is 5.5–6.5. Drainage holes are non-negotiable; never let the plant sit in standing water in a saucer.
