What’s Wrong With My Alocasia?

If your Alocasia looks unhappy, the symptoms usually point to a few common problems. Yellow leaves, brown tips, curling edges, drooping, or dripping are signs of stress in water, light, humidity, or nutrition. By matching the symptom to its cause, you can fix issues quickly and bring your plant back to health with the right care and regular feeding from CompleteGrow All Purpose Liquid NPK 20-20-20.

At a Glance: Quick Diagnostic Guide

Yellow leaves: Overwatering, nutrient deficiency, or dormancy
Brown tips/edges: Low humidity, salt build-up, or dry soil
Curling leaves: Drought stress, pests, or excess light
Drooping leaves: Water imbalance, cold drafts, or dormancy
Dripping water: Natural guttation, overwatering, or high humidity
No growth/decline: Dormancy, root rot, or lack of feeding

Quick Fix: Start by checking soil moisture and roots, then adjust humidity, light, and fertiliser routine with CompleteGrow 20-20-20.

Leaf Colour & Texture Issues

Yellowing: The most common complaint. Caused by overwatering, nitrogen deficiency, or natural leaf ageing. Solution: Balance watering, feed fortnightly, and trim only the oldest leaves.

Browning: Brown patches or crispy edges usually mean low humidity or salt build-up from fertiliser. Solution: Raise humidity and flush soil every 6–8 weeks.

Curling vs Drooping

Curling leaves: A protective response to drought, low humidity, or pest damage.
Drooping leaves: May indicate dormancy, root stress, or inconsistent watering. Identify whether the whole plant is affected or just a few older leaves.

Growth & Environmental Problems

No new leaves: If your Alocasia stalls, it may be in seasonal dormancy (common in winter) or lacking nutrients. Solution: Be patient in dormancy and feed with CompleteGrow 20-20-20 in spring.

Dripping leaves: Called guttation — normal in moderation, but heavy dripping may signal overwatering or excess fertiliser.

Pests & Diseases

Spider mites, thrips, and scale insects weaken leaves, causing yellow spots, curling, and general decline. Fungal leaf spots may also appear in high humidity with poor airflow. Solution: Inspect leaves regularly and treat early with neem oil or insecticidal soap.

Keeping Alocasia Healthy Long-Term

Watering: Even moisture — not soggy, not dry.
Humidity: Maintain 60–70% indoors.
Light: Bright-indirect light, never harsh direct sun.
Nutrition: Feed with CompleteGrow 20-20-20 every 10–14 days in the growing season.
Seasonal care: Expect some leaf drop during dormancy — this is normal.

FAQs

Is my Alocasia dead if it lost all its leaves? Not always — check the corm. If firm, it can regrow in spring.
Why do new leaves look weak or deformed? Usually from low humidity or nutrient deficiency during unfurling.
Can Alocasia recover from root rot? Yes, if some roots and the corm are still healthy. Remove rot, repot, and resume light feeding.
Why does my Alocasia keep declining despite care? Often a mix of low light, poor soil aeration, and irregular watering — correcting all three together usually helps.
