How to Grow and Care for Alocasia zebrina ‘Reticulata’ Indoors

• Light: Provide bright, filtered light; direct midday sun can scorch the foliage.
• Watering: Keep soil evenly moist but never waterlogged; allow the top 2 – 3 cm to dry before watering again.
• Humidity: Maintain 60 – 80%; low humidity can cause leaf edges to brown.
• Temperature: Ideal range is 20 – 28 °C; avoid cold drafts or sudden fluctuations.
• Soil: Use a chunky, well-draining aroid mix with bark, perlite, and organic matter for aeration.
• Potting: Choose a stable, weighted pot to prevent tipping, as the long petioles can make the plant top-heavy.
• Repotting: Refresh the substrate every 12 – 18 months or when roots fill the container.
• Feeding: Apply a diluted, balanced fertilizer every 4 – 6 weeks during the growing season.
• Propagation: Best done by dividing rhizomes during repotting.
• Semi-Hydro: Performs well in inert substrates with stable moisture and nutrient supply.
• Toxicity: All parts are poisonous if ingested – keep away from pets and children.

Common Problems and Practical Fixes

• Pests: Monitor for spider mites, thrips, and mealybugs; treat early with neem oil or systemic insecticide.
• Leaf Yellowing: Usually linked to overwatering or low light – adjust conditions promptly.
• Browning Tips: Common with low humidity or irregular watering; stabilize humidity and moisture.
• Root Rot: Prevent with a fast-draining substrate and avoid waterlogged conditions.
