🌱 How to Care for Dragon Scale Alocasia to Prevent Fungus Gnats?

💧 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.
