Anthuriums are most commonly known for their flowering varieties also known as flamingo flowers or laceleaf, and are admired for their glossy leaves and striking, long-lasting flowers. This guide will cover general care tips for anthuriums such as these but will also include care tips for the more fussy and collectible specimens such as the King Anthurium (Anthurium veitchii) and Queen Anthurium (Anthurium warocqueanum), which are known for their impressive foliage.
1. Light Requirements
Anthuriums prefer bright, indirect light. Direct sunlight can scorch their leaves, while too little light can reduce flowering. Place your anthurium near a window with filtered light, such as an east or north-facing window. If natural light is insufficient, you can use fluorescent or LED grow lights to supplement. King and Queen Anthuriums, with their large leaves, particularly benefit from ample light to maintain their vibrant appearance.
2. Watering
Anthuriums like their soil to be consistently moist but not waterlogged. Water your anthurium when the top 1-2 inches of soil feel dry. Use room-temperature water and ensure the pot has good drainage to prevent root rot. During the growing season (spring and summer), you may need to water more frequently. In the winter, reduce watering to allow the soil to dry out slightly between waterings. Both King and Queen Anthuriums are sensitive to overwatering, so it’s crucial to find a balance.
3. Humidity and Temperature
Anthuriums thrive in high humidity. If your home is dry, consider misting the leaves regularly, using a humidifier, or placing the plant on a pebble tray with water. Ideal temperatures for anthuriums range from 18-27°C. Avoid placing them near drafts, air conditioners, or heaters, as sudden temperature changes can stress the plant. Queen Anthuriums, in particular, require higher humidity levels (above 50%) to prevent leaf damage.
4. Soil and Fertilization
Use a well-draining, peat-based potting mix, such as a blend of peat moss, pine bark, and perlite. This mimics their natural epiphytic growing conditions. Fertilize your anthurium every 6-8 weeks during the growing season with a balanced, water-soluble fertilizer diluted to half strength. Avoid fertilizing in the winter when the plant is not actively growing. King and Queen Anthuriums benefit from a fertile but well-draining mix to support their large leaves.
5. Pruning and Maintenance
Regularly remove any yellow or dead leaves to keep your plant healthy. Wipe the leaves with a damp cloth to remove dust and allow for better photosynthesis. Anthuriums produce flowers on new growth, so avoid cutting back the long tendrils where flowers form. If your anthurium becomes leggy, you can prune it back to encourage bushier growth. For King and Queen Anthuriums, maintaining clean leaves is essential to showcase their impressive foliage.
6. Repotting
Anthuriums prefer to be slightly root-bound, so repotting is only necessary every 2-3 years or when the plant outgrows its pot. When repotting, choose a pot that is only slightly larger than the current one to prevent waterlogging. Refresh the potting mix to provide new nutrients. Repotting in the spring is ideal, as this is when the plant is actively growing. King and Queen Anthuriums may require larger pots due to their size.
7. Propagation
Anthuriums can be propagated through division or stem cuttings. For division, carefully separate the root clumps and plant them in fresh potting mix. For stem cuttings, take a cutting with at least two nodes and place it in water or a moist potting mix. Keep the cutting in a warm, humid environment until roots develop. Once rooted, transfer the cutting to a small pot with well-draining soil. Propagation can be more challenging with King and Queen Anthuriums due to their size and growth habits.
8. Pest Control
Anthuriums are generally resistant to pests, but they can occasionally attract mealybugs, spider mites, or aphids. Inspect your plant regularly and treat any infestations promptly with insecticidal soap or neem oil. Keeping the plant clean and maintaining high humidity can help prevent pest problems. If you notice pests, isolate the affected plant to prevent the spread to other houseplants.
9. Flowering
Anthuriums are known for their beautiful, long-lasting flowers, which typically bloom in clusters. To encourage blooming, provide plenty of bright, indirect light and avoid moving the plant once buds have formed. Some anthuriums may take a few years to bloom, so patience is key. Flowering can also be stimulated by a slight drop in temperature at night. King and Queen Anthuriums are more prized for their foliage, but they can also produce flowers under optimal conditions.
10. Common Issues and Solutions
Yellow Leaves: Often a sign of overwatering or poor drainage. Ensure the soil dries out between waterings and the pot has adequate drainage.
Leaf Drop: Can be caused by sudden changes in temperature, overwatering, or underwatering. Maintain consistent care routines.
Brown Leaf Tips: Usually due to low humidity or over-fertilization. Increase humidity and reduce fertilizer application.
Wrinkled Leaves: Indicative of underwatering. Water the plant thoroughly and adjust your watering schedule.
By following these care tips, your anthuriums, including the majestic King and Queen varieties, will thrive and bring a touch of tropical beauty to your home. Happy growing!
