The King Anthurium, scientifically known as Anthurium veitchii, is a sought-after houseplant. Its striking appearance, with unusually long, deeply corrugated leaves, earns it the moniker “King.” These prominent, rippled leaves can extend significantly, creating a unique texture and focal point. Native to the tropical rainforests of Colombia, this aroid’s foliage develops over several years, becoming an impressive specimen.
Essential King Anthurium Care
Light
King Anthuriums flourish in bright, indirect light. An east-facing window is often suitable, providing ample light without harsh direct sun exposure. Placing the plant too close to south or west-facing windows can lead to leaf burn and stunted growth. Filtering light with sheer curtains or positioning the plant further from the window is advisable.
Watering
Maintaining consistent moisture is important for the King Anthurium. Water when the top one to two inches of potting mix feel dry to the touch. Thoroughly drench the soil until water drains from the bottom, promptly emptying any excess from the tray. Overwatering can lead to root rot, while insufficient watering causes yellowing or browning leaves. Regular checks of soil moisture are more effective than a strict watering schedule.
Soil Requirements
The King Anthurium, an epiphyte, requires a potting mix with excellent aeration and drainage. A chunky, well-draining substrate is optimal. Ideal mixes include orchid bark, perlite, coco coir, and horticultural charcoal. This mix ensures ample airflow around the roots, preventing compaction and waterlogging. Avoid dense, all-purpose garden soils, as these can suffocate roots and lead to plant decline.
Temperature and Humidity
King Anthuriums thrive in warm, stable temperatures, ideally between 59°F (15°C) and 79°F (26°C). They are sensitive to cold drafts and sudden temperature fluctuations. High humidity is also a significant factor, with levels above 60% being beneficial. Consider using a humidifier, grouping plants, or placing the pot on a pebble tray, ensuring good air circulation.
Fertilizing
During the active growing season (spring and summer), King Anthuriums benefit from regular fertilization. Apply a balanced liquid houseplant fertilizer, diluted to half strength, once or twice a month. Some growers fertilize at every watering with a very dilute solution. Given their epiphytic nature, they are not accustomed to rich soil-based nutrients, so a gentle approach is preferred. Reduce or cease fertilizing during fall and winter when growth slows.
Repotting Your King Anthurium
Repotting the King Anthurium is infrequent due to its slow growth, typically every two to three years. Indicators include roots emerging from drainage holes, the plant appearing top-heavy, or the potting mix breaking down. The best time to repot is spring or early summer, during active growth.
When repotting, select a pot only one or two inches larger than the current one. A pot that is too large can hold excessive moisture, increasing root rot. Gently remove the plant, carefully loosening circling roots and removing old potting mix. Position the plant in the new pot, filling with fresh, well-draining aroid mix, ensuring the plant is at the same depth.
Troubleshooting Common King Anthurium Problems
Issues with King Anthuriums often signal care problems. Yellowing leaves often indicate overwatering (especially if soil is soggy), insufficient light, or nutrient deficiency. If yellowing accompanies soft, dark brown spots or a foul soil smell, root rot may be present, requiring root inspection and repotting into fresh, well-draining media.
Browning leaf tips or edges commonly signal low humidity or underwatering. Crispy brown spots on leaves can also result from too much direct sunlight. Stunted growth might indicate inadequate light, improper watering, or a lack of nutrients, suggesting a care review.
King Anthuriums can encounter pests like spider mites, mealybugs, thrips, and aphids. Regular inspection, especially of leaf undersides, helps detect infestations early. If pests are found, wiping leaves with a damp cloth or applying insecticidal soap or neem oil can manage them. Fungal issues, like root rot or leaf spots, link to persistently wet conditions and poor air circulation, highlighting the importance of proper watering and an airy environment.
