Sunlight
Alocasia prefers bright indirect light, ideally positioned near a large east- or west-facing window where it receives gentle morning or afternoon sun. Direct midday sun will scorch the leaves quickly, leaving crispy brown patches. In lower light, growth stalls and the plant becomes vulnerable to overwatering issues.
Water
Water when the top half of the soil is dry, then drain thoroughly. Alocasia is particularly prone to root rot, so never let the pot sit in a saucer of standing water. In winter, growth slows considerably and the plant may even go dormant, so reduce watering frequency and let the soil dry a little more between sessions.
Toxicity
Toxic to cats, dogs, and humans. All parts of Alocasia contain insoluble calcium oxalate crystals, which cause intense burning and irritation of the mouth, tongue, and throat on contact, along with drooling, pawing at the face, and difficulty swallowing. Symptoms in people typically include burning pain and swelling if sap contacts the skin or mouth. If ingestion is suspected, contact your veterinarian or nearest emergency animal hospital right away.
Common Problems
Yellowing leaves are the most frequent complaint and usually point to overwatering or poor drainage; always check the roots for rot before adjusting your care routine. Spider mites and mealybugs are common pests, especially in the dry air of Canadian winters, so inspect the undersides of leaves regularly and treat early with neem oil or insecticidal soap. Alocasia can drop leaves dramatically when moved or stressed by temperature fluctuations, so keep it away from cold drafts and heating vents.
