Aglaonema is a genus of flowering plants in the arum family, Araceae. They are native to tropical and subtropical regions of Asia and New Guinea. They are known commonly as Chinese evergreens. The Chinese Evergreen family is among the top houseplants that purify the air and is also on Nasa’s list of air-purifying plants.
Aglaonema ‘Red Emerald’ features deep green leaves with a glossy finish. What sets it apart is the vibrant red or burgundy undersides of the leaves, which can be seen when the leaves curl or from below. This contrast between the green tops and red undersides gives it a distinctive, almost exotic look.
Like other Aglaonemas, it grows in a bushy, upright manner. It’s relatively slow-growing, which makes it manageable for indoor spaces. This variety can reach heights of 2 to 3 feet.
Care Requirements
- Light: ‘Red Emerald’ prefers bright, indirect light. It can tolerate lower light conditions, but the red coloration might become less pronounced. Direct sunlight should be avoided as it can scorch the leaves.
- Watering: Allow the top inch or two of soil to dry out between waterings. Overwatering can lead to root rot, which is a common issue with Aglaonemas. Ensure the pot has good drainage.
- Soil: A well-draining potting mix is essential. Adding perlite or orchid bark to regular potting soil can improve drainage.
- Humidity: While it can adapt to average household humidity, it thrives in higher humidity. You can increase humidity by misting the leaves, using a pebble tray, or placing a humidifier nearby.
- Temperature: Prefers temperatures between 60-80°F (16-27°C). Keep away from cold drafts, air conditioners, or heaters.
- Fertilization: Feed with a balanced houseplant fertilizer every 2-3 months during the growing season (spring and summer). Over-fertilization can lead to leaf burn.
Challenges
- Leaf Browning: Can occur due to low humidity, fluoride in water, or too much direct sunlight. Using distilled or rainwater can help prevent this.
- Pests: Watch out for common houseplant pests like spider mites, mealybugs, or scale. Regularly inspect the plant, especially the undersides of leaves.
- Growth Issues: If the plant doesn’t receive enough light, it might grow leggy or lose its vibrant coloration. Rotate the plant periodically to ensure even growth.
