Care Guide for Alocasia macrorrhizos 'Stingray'

• Light: Bright, indirect light suits it best; soft morning sun tolerated. Avoid harsh midday rays.
• Watering: Let the top 10 – 15 % of substrate dry before re-watering. Consistent moisture without stagnation is key. Read our houseplant watering guide for full tips.
• Humidity: Maintain 60 – 80 %. Stable humidity promotes flawless, glossy leaves.
• Temperature: Keep between 20 – 30 °C; protect from drafts and dips below 15 °C. More on seasonal adjustment in our houseplant dormancy guide.
• Soil: Use an airy mix of coconut coir, orchid bark and perlite. For composition details, visit our best aroid substrate guide.
• Fertilizer: Feed every 4 – 6 weeks with a diluted, balanced liquid fertilizer during active growth.
• Potting: Choose a heavy terracotta or ceramic pot with drainage; repot every 1 – 2 years as roots expand.

Propagation

• Offsets: Detach rooted pups from the parent during repotting and plant separately.
• Corms: Sprout basal corms in moist substrate until roots appear, then pot individually.

Troubleshooting & Solutions

• Yellow leaves: Usually from overwatering or compact soil; see our root-rot prevention guide for rescue steps.
• Brown tips: Indicate dry air or inconsistent watering–raise humidity.
• Drooping leaves: Temporary stress from temperature swings or dehydration; stabilize care routine.
• Pests: Check for spider mites or thrips. Preventative methods covered in our pest-control articles.
• Fungal spots: Improve airflow, remove affected foliage, and keep leaves dry.

Pro Care Tips

• Leaf cleaning: Wipe gently with a damp microfiber cloth to maintain shine and remove dust.
• Rotation: Turn the pot every few weeks for balanced growth and symmetry.
• Environmental stability: Avoid sudden changes in temperature, light or humidity.

Etymology and Background

The species name macrorrhizos comes from the Greek makros (“large”) and rhiza (“root”), describing its massive rhizomes. The cultivar name 'Stingray' reflects its distinctive leaf form reminiscent of a stingray gliding through water–an instantly recognisable feature among Alocasia plants.
