Alocasia Macrorrhizos (Giant Elephant Ear)

• Native to Southeast Asia and Australia's rainforest regions, this tropical giant has been cultivated for centuries. The name 'macrorrhizos' means 'large root' in Greek.
• Individual leaves can reach over 1.5 metres long and 1 metre wide, making it one of the largest-leafed houseplants available. The thick stems store water and nutrients.
• Goes dormant in cooler months, with leaves naturally dying back before spectacular regrowth in spring. This survival mechanism helps it through dry seasons.
• Loved for its architectural presence and ability to create instant tropical atmosphere in any setting.

• Water when top 2cm of soil dries out, typically every 7-10 days in summer, less in winter. Always check soil moisture rather than following rigid schedules.
• Position in bright, indirect light indoors or dappled shade outdoors. Avoid direct afternoon sun which burns the large leaves.
• Use rich, well-draining potting mix with added perlite or bark chips. Ensure pots have drainage holes to prevent waterlogging.
• Feed with balanced liquid fertiliser monthly during spring and summer growing season. Reduce to every 6-8 weeks in winter.
• Remove yellowing or damaged leaves at the base with clean secateurs. Natural leaf drop occurs in winter dormancy.
• Maintain humidity above 50% using pebble trays, grouping plants together, or running a humidifier nearby.
• Protect from temperatures below 15°C and cold drafts. Bring potted plants indoors during Australian winter in cooler regions.

• Provide bright, indirect light indoors or filtered shade outdoors to prevent leaf burn. Direct sunlight will scorch the massive leaves.
• Water when top 2cm of soil feels dry, maintaining consistent moisture without waterlogging. Reduce watering significantly in winter months.
• Maintain high humidity around 60-70% using pebble trays or humidifiers. Low humidity causes brown leaf edges.
• Keep temperatures between 18-26°C year-round, protecting from cold drafts and sudden temperature changes.
• Feed monthly with liquid fertiliser during growing season (spring-autumn) to support rapid leaf development.

• Spider mites thrive in dry conditions, causing yellowing leaves with fine webbing. Increase humidity and spray with neem oil weekly.
• Root rot occurs from overwatering, showing as black mushy roots and yellowing leaves. Reduce watering and repot in fresh, well-draining soil.
• Scale insects appear as small brown bumps on stems and leaves, sucking plant sap. Remove manually and treat with horticultural oil.
• Leaf drop happens during winter dormancy or temperature stress. Maintain consistent warmth and reduce watering during cooler months.
