Alocasia Dragon Scale problems — and how to fix them

Its thick, textured leaves are especially prone to spider mites, which thrive in dry air. Inspect leaf undersides for fine webbing and stippling; rinse foliage, raise humidity, and treat repeatedly with neem oil or insecticidal soap to break the life cycle.

Soggy soil is the leading cause of yellowing leaves and root rot. Let the top 1-2 inches dry between waterings, ensure the pot drains freely, and use a chunky aroid mix rather than dense potting soil.

Browning, crispy margins usually signal humidity that is too low (below ~60%) or inconsistent watering. Add a humidifier or pebble tray and keep the mix evenly moist.

Shorter days and cooler temperatures can trigger dormancy, with slowed growth or dieback. This is normal: keep the corm barely moist and warm, ease off feeding, and it usually pushes new leaves again in spring.

Sap-sucking mealybugs (white cottony masses) and scale insects can colonise stems and leaf joints. Wipe them off with isopropyl alcohol on a cotton swab and follow up with neem oil or insecticidal soap.

Direct sunlight bleaches and burns the prized scale-like markings. Move the plant to bright indirect light or filter the light with a sheer curtain.
