Troubleshooting
Alocasia Longiloba problems — and how to fix them
Alocasia Longiloba (Alocasia longiloba) 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.
Yellowing leaves
Frequently overwatering or poor drainage; can also be the natural loss of the oldest leaf as a new one emerges. Check the mix is airy and not soggy, and water only when the surface dries.
Brown leaf tips and edges
Typically low humidity or dry air, sometimes with salt buildup. Raise humidity toward 60-70%, keep moisture even, and flush the soil.
Drooping petioles
Inconsistent watering or temperatures below 15°C stress the plant. Keep warmth stable, avoid cold drafts, and maintain even soil moisture.
Spider mites
Dry air favours these pests, leaving stippling and webbing on the slender leaves. Inspect undersides, rinse foliage, raise humidity, and treat with insecticidal soap or neem.
