Anthurium Watermaliense: Easy Care Guide for Beginners

Introduction to Anthurium Watermaliense

Anthurium Watermaliense, also known as the black anthurium, is a striking houseplant that is renowned for its glossy, dark foliage and stunning, paddle-shaped leaves. Native to Central and South America, this epiphytic perennial is part of the Araceae family. It is highly sought after by plant enthusiasts for its unique appearance and relatively easy care requirements, making it an ideal choice for beginners looking to add some exotic flair to their indoor plant collection.

Optimal Lighting and Placement

Lighting is crucial for the health and growth of Anthurium Watermaliense. The plant thrives in bright, indirect light. Direct sunlight can scorch the leaves, while too little light may cause the plant to become leggy and inhibit flowering. A north or east-facing window covered with a sheer curtain is an ideal spot, providing gentle, filtered light throughout the day.

Temperature and Humidity Needs

Anthurium Watermaliense prefers a warm, humid environment mimicking its native tropical habitat. Aim to maintain indoor temperatures between 65°F and 80°F (18°C to 27°C). Avoid placing your plant near drafts, air conditioning vents, or radiators, as sudden temperature fluctuations can be harmful. As for humidity, aim for levels above 60%. Using a humidifier, misting the plant regularly, or placing it on a pebble tray with water can help maintain the desired humidity.

Watering and Feeding

Watering your Anthurium Watermaliense properly is key to its well-being. Water the plant when the top inch of soil feels dry to the touch. Use lukewarm water to avoid shocking the plant’s roots, and ensure the pot has adequate drainage to prevent root rot. Overwatering is a common mistake, so be cautious and check the soil moisture before adding more water.

Fertilization Requirements

Feeding your Anthurium Watermaliense helps to provide the necessary nutrients for it to flourish. During the growing season (spring and summer), use a balanced, water-soluble fertilizer once a month. Dilute the fertilizer to half the recommended strength to avoid the buildup of mineral salts in the soil, which can be damaging to the roots.

Soil and Repotting

The ideal soil for Anthurium Watermaliense should be well-draining and rich in organic matter. A mix of peat, pine bark, and perlite or vermiculite works well in creating an environment that holds moisture but allows excess water to drain quickly. Repotting should be done every two to three years or when you notice the roots outgrowing the pot. Choose a container only slightly larger than the current one, as anthuriums perform better when slightly root-bound.

Pruning and Maintenance

Regular pruning will keep your Anthurium Watermaliense looking its best. Remove yellow or damaged leaves using sterile pruning shears to prevent disease spread and encourage new growth. Additionally, pruning can help maintain the plant’s size and shape. Wiping the leaves with a damp cloth not only removes dust but also allows the plant to breathe better and perform photosynthesis more efficiently.

Pest and Disease Management

While relatively resilient, Anthurium Watermaliense is not immune to pests and diseases. Common issues include aphids, scale insects, and mealybugs. Inspect your plant regularly and if pests are detected, treat them promptly with insecticidal soap or neem oil. Keep an eye out for root rot, caused by overwatering, and if detected, repot the plant in fresh soil after removing any affected roots.


The Anthurium Watermaliense is a beautiful and rewarding plant to grow. Its exotic appearance can add a touch of elegance to any interior space, and its undemanding care regimen makes it approachable for novice gardeners. By providing the right balance of light, water, humidity, and nutrients, you can enjoy the lush, vibrant beauty of this stunning anthurium species for many years to come.
