How to Care for Anthurium clarinervium: Complete Growing Guide

Quick Care Summary

To care for your Anthurium clarinervium, place it in a spot with bright, indirect light, about 3 feet from an east- or west-facing window. Water your plant every 7-10 days in the summer and every 14 days in the winter, making sure the soil is moist but not waterlogged. Keep the temperature between 65-80°F (18-27°C) and maintain a medium humidity level, around 50-70%. This plant is relatively easy to care for and can thrive in a variety of conditions, making it perfect for beginners.

Overview

The Anthurium clarinervium is native to the tropical regions of Mexico and Central America, where it grows in the understory of rainforests. It's a member of the Arum family and is known for its unique, velvety leaves with prominent veins. The plant can grow up to 2 feet tall and 1 foot wide, making it a great choice for small spaces. Its popularity as a houseplant stems from its ability to thrive in low-light conditions and its air-purifying properties, which can help remove pollutants like formaldehyde and benzene from the air.

The Anthurium clarinervium is a relatively slow-growing plant, but it can be propagated easily through division or leaf cuttings. It's a great choice for indoor gardens due to its low-maintenance requirements and its ability to tolerate a range of temperatures and humidity levels. In its natural habitat, the plant grows on the forest floor, where it receives dappled light and high humidity. To replicate these conditions indoors, you can use a humidifier and place the plant in a spot with bright, indirect light.

Light: The Importance of Bright, Indirect Light

The Anthurium clarinervium requires bright, indirect light to photosynthesize and grow. A spot with 200-400 foot-candles of light is ideal, which is about 3 feet from an east- or west-facing window. Avoid placing the plant in direct sunlight, as it can cause the leaves to become scorched and discolored. In the winter months, when the days are shorter and the light is less intense, you may need to move the plant closer to the window or use a grow light to supplement the natural light.

Watering: How to Water Your Anthurium clarinervium

Watering your Anthurium clarinervium is a delicate process, as the plant is sensitive to overwatering. Check the soil moisture by sticking your finger into the soil up to the first knuckle. If the soil feels dry, it's time to water. Water the plant every 7-10 days in the summer and every 14 days in the winter, making sure the soil is moist but not waterlogged. Use room-temperature water, and avoid getting water on the leaves to prevent fungal diseases.

Soil & Repotting: The Importance of Well-Draining Soil

The Anthurium clarinervium requires well-draining soil to prevent waterlogged soil and root rot. Use a potting mix that contains 60% potting mix, 30% perlite, and 10% orchid bark. Avoid using regular potting soil, as it can retain too much water and cause the roots to rot. Repot the plant every 2-3 years in the spring, when it becomes pot-bound. Choose a pot that is only 1-2 sizes larger than the original pot, and gently remove the plant from the pot, taking care not to damage the roots.

Fertilizing

Fertilize your Anthurium clarinervium with a balanced 10-10-10 fertilizer during the spring and summer months. Dilute the fertilizer to half the recommended strength to prevent burning the roots. Avoid fertilizing during the winter months, when the plant is dormant.

Humidity and Temperature

The Anthurium clarinervium requires a medium humidity level, around 50-70%. Use a humidifier to maintain a consistent humidity level, especially during the dry winter months. Keep the temperature between 65-80°F (18-27°C), avoiding temperatures above 85°F (29°C) or below 55°F (13°C).

Toxicity & Safety

The Anthurium clarinervium is non-toxic to cats and dogs, according to the ASPCA. However, it's still possible for pets to experience gastrointestinal upset if they ingest the plant. Keep the plant out of reach of pets to prevent accidental ingestion. If you suspect your pet has ingested the plant, contact the ASPCA Animal Poison Control Center at (888) 426-4435.

Common Problems

Symptom	Most Likely Cause	Quick Fix	Prevention
Yellowing leaves	Overwatering	Reduce watering frequency	Check soil moisture regularly
Brown tips	Underwatering	Increase watering frequency	Water plant regularly
Pests	Spider mites or mealybugs	Treat with insecticidal soap	Inspect plant regularly for pests
Root rot	Waterlogged soil	Improve drainage	Use well-draining potting mix
Slow growth	Lack of light	Move plant to brighter location	Use grow light if necessary

Overwatering

Overwatering is one of the most common problems with the Anthurium clarinervium. If you notice the leaves are yellowing or the stems are soft and mushy, it's likely due to overwatering. Reduce the watering frequency and improve the drainage by repotting the plant in a well-draining potting mix.

Underwatering

Underwatering can also cause problems for the Anthurium clarinervium. If you notice the leaves are brown or crispy, it's likely due to underwatering. Increase the watering frequency, but make sure not to overwater.

Pests

Pests like spider mites and mealybugs can infest the Anthurium clarinervium. If you notice small, moving dots on the leaves or stems, it's likely due to pests. Treat the plant with insecticidal soap, and inspect the plant regularly to prevent future infestations.

Root Rot

Root rot is a common problem with the Anthurium clarinervium, especially if the soil is waterlogged. If you notice the stems are soft and mushy, or the leaves are yellowing, it's likely due to root rot. Improve the drainage by repotting the plant in a well-draining potting mix, and reduce the watering frequency.

Slow Growth

Slow growth can be a problem with the Anthurium clarinervium, especially if the plant is not receiving enough light. If you notice the plant is not growing as quickly as expected, it's likely due to lack of light. Move the plant to a brighter location, or use a grow light to supplement the natural light.

Where to Buy & What to Look For

The Anthurium clarinervium is available at most nurseries and online plant retailers. When purchasing a plant, look for one with healthy, green leaves and a sturdy stem. Avoid plants with yellow or brown leaves, or those that are wilting or soft. The price range for an Anthurium clarinervium is around £20-£50 for a small plant, and £50-£100 for a larger plant.

Propagation

To propagate an Anthurium clarinervium, follow these steps:

1. Cut a stem from the mother plant, just above a node.
2. Remove the lower leaves, leaving only the top two or three leaves.
3. Place the cutting in a glass of water or a propagation tray, and keep the soil moist.
4. Roots should develop within 1-2 weeks, and the plant can be transplanted into a pot.
5. Keep the soil moist and warm, and provide bright, indirect light.
