Here are tips on growing the Amazon elephant’s ear:
- Light: Bright, indirect light. They can survive in 80% shade but prefer about 60% shade. Do not expose to strong, direct sunlight.
- Water: Like most alocasias, the Amazon elephant’s ear likes wet feet. Keep the potting media moist at all times. A rest period should be allowed in winter by allowing the soil to become almost dry between waterings and stop fertilizing. If it dries completely it may go dormant, however, it will recuperate in a month or two, with good care.
- Temperature: This is a tropical plant that will go dormant or die if exposed to cold. Do not let temperature remain under 50 F. If the plant does go dormant, you may be able to dig up the corm and save it until warmer conditions are possible.
- Humidity: These plants like slightly higher humidity levels than many other plants. You may need to raise the humidity levels in a room artificially by placing the plant in a humidity tray with pebbles or use a humidifier.
- Soil: These plants like a fast-draining, well-aerated potting soil.
- Fertilizer: Feed with a diluted balanced fertilizer from spring every 2 weeks and stop at the end of August then start again at the beginning of spring.
