Alocasia Lauterbachiana (Purple Sword) problems — and how to fix them

Alocasia Lauterbachiana (Purple Sword) (Alocasia lauterbachiana) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.

Root and corm rot

The most common killer, caused by overwatering or poor drainage, especially in low light. Use a chunky mix, water only when the top third dries, and never let it stand in water.

Spider mites and mealybugs

Sap-sucking pests that hide on leaf undersides and stems, thriving in dry air. Inspect regularly, rinse the foliage, and treat with insecticidal soap or neem if found.

Yellowing leaves

Usually a sign of overwatering or inconsistent moisture. Check that the soil is draining freely and let the top of the mix dry before watering again.

Brown, crispy leaf tips and edges

Typically caused by low humidity or mineral build-up from tap water. Raise humidity with a pebble tray or humidifier and use dechlorinated or filtered water.

Leggy, stretched growth and pale leaves

Indicates insufficient light. Move it to a brighter spot with bright, indirect light, away from scorching direct sun.

Dormancy / leaf drop

In cooler months Alocasia can slow down or drop leaves and go semi-dormant. Reduce watering and stop feeding; healthy plants typically push out new growth again in spring.
