Alocasia Triangularis problems — and how to fix them
Alocasia Triangularis (Alocasia triangularis) 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.
Brown, crispy leaf tips
The sharp leaf points are first to brown in low humidity or with salt buildup. Raise humidity toward 60-70%, keep moisture even, and flush the soil periodically.
Yellowing leaves
Often overwatering or poor drainage; can also be natural loss of the oldest leaf as a new one unfurls. Check the mix is airy and water only when the surface dries.
Drooping petioles
Inconsistent watering, cold below 15°C, or sudden environmental change. Keep warmth stable, avoid drafts, and maintain even soil moisture.
Spider mites
Dry indoor air favours mites, seen as stippling and webbing. Inspect undersides, rinse foliage, raise humidity, and treat with insecticidal soap or neem.
