Origin notes for Alocasia sp. Papua

The exact origin and natural habitat of Alocasia sp. Papua are unknown.

Care for Alocasia sp. Papua

• Light: Place it somewhere bright with diffuse light and protect it from strong midday or afternoon sun.
• Watering: While it is growing, water again once the mix has begun to dry, before the potting mix dries all the way through. Water until excess runs from the drainage holes. Let the pot drain, then empty any water left in the saucer or cover pot.
• Potting mix: Use a loose mix that drains freely but does not dry abruptly. Keep the pot reasonably close to the roots.
• Temperature: Keep it around 18–29 °C and away from cold windows or draughts. Move it away from cooler spots before temperatures fall below 15 °C.
• Humidity: Alocasia does best with medium to high humidity. Keep it in a bright spot away from heaters and air-conditioning. If the air is dry, place it near other houseplants that like similar conditions, leaving space between the leaves, or use a clean humidifier.

Alocasia sp. Papua: common issues

• Leaves yellow and droop soon after watering: Check whether the potting mix is staying wet around the roots for too long. Let the upper layer begin to dry and check that water runs out of the pot easily after watering. If the plant keeps declining, inspect the roots and base before adding more water. If clearly rotten tissue has to be removed, use a disinfected blade, keep every firm healthy section, clean the blade between cuts and discard the removed material.
• Crisp tan or bleached patches develop mainly on the window-facing side: Pull the plant back from the hot window so direct sun no longer reaches it, while keeping the position bright and filtered. Existing scorch will remain visible, so judge the correction by fresh growth rather than the damaged patch.
• Fine pale dots spread and delicate webbing appears underneath the leaves: Search the lower leaf surfaces, especially where the larger veins branch, for tiny moving spider mites. If you see them, keep the plant apart from your other plants and rinse both sides of the leaves where practical. Use a treatment labelled for spider mites on indoor ornamental plants, and repeat it only as directed on the label.

Alocasia sp. Papua: toxic if chewed

• Pets: This Alocasia is toxic to cats and dogs. Keep the plant and any cut pieces where pets cannot chew them.
• Children and handling: Keep it out of reach of children. Sap from damaged tissue can irritate skin and eyes, so wash your hands after pruning and avoid touching your face.
• Why it irritates: Alocasia tissue contains insoluble calcium oxalate crystals. Chewing or contact with sensitive tissue can cause immediate local irritation.
• Possible symptoms: Mouth exposure can cause burning pain, drooling, swelling, nausea or vomiting, and difficulty swallowing.
• After exposure: For a pet, contact a veterinarian. For a person, remove any plant material from the mouth and rinse with water; seek medical or poison-control advice if symptoms are significant. Breathing difficulty or rapidly increasing swelling needs urgent medical attention.
