Anthurium plants, known for their vibrant, colorful leaves and spathes, are a popular choice for many indoor gardeners. However, these tropical beauties have specific light requirements that need to be met in order for them to flourish and produce their stunning flowers. Understanding these requirements is essential to ensure the health and happiness of your anthurium plant.

Anthuriums thrive best in bright, indirect light, which helps them produce flowers and maintain lush, vibrant leaves. Too much direct sunlight can lead to scorching and dehydration, while insufficient light can result in thin, straggly leaves and poor flower production. To achieve the right balance, it’s important to place your anthurium where it can receive the optimal amount of indirect light for healthy growth. Ideally, this translates to about 500-1000 footcandles or 15 to 100 μmol/m²/s in PPFD values for 10-12 hours a day.

In addition to light, other factors such as humidity, temperature, and water requirements also play a critical role in the overall health of your anthurium plant. By carefully monitoring these conditions and providing the appropriate amount of indirect light, you’ll be able to enjoy the striking beauty of your anthurium plant all year round.

Anthurium Light Requirements

Bright Indirect Light

Anthuriums thrive in bright, indirect light, as it encourages healthy growth and blooming. This tropical plant prefers a spot near a window that receives filtered sunlight but not directly exposed to the sun’s harsh rays. The ideal light intensity for anthuriums is between 15 and 100 μmol/m²/s. To achieve this, aim for an equivalent of a minimum of 400 footcandles (fc) for 10-12 hours per day.

Avoid Direct Sunlight

Direct sunlight can harm your anthurium, causing problems like scorching and dehydration. It’s crucial to keep your plant shielded from harsh direct sun rays to maintain its vibrant foliage and beautiful blooms. Overexposure to sunlight can result in leaf burns and inhibit the plant’s growth. Ensure your anthurium is placed in a location with bright, indirect light to avoid these issues.

Signs of Inadequate Light

Understanding the signs of inadequate light is essential to ensure your anthurium’s proper growth and development. If your plant is not receiving enough light, it may struggle to produce flowers and develop thin, straggly leaves. On the other hand, too much light can cause dehydrated and scorched leaves. By paying attention to these signs, you can adjust your anthurium’s location accordingly and provide it with the perfect light level for optimum health and growth.

Adapting to Lighting Conditions

Adjusting for Low Light

Anthurium plants are known for their ability to adapt to various lighting conditions, including low light. While they may not thrive as much as they would in brighter conditions, they can still grow and survive. To help your Anthurium adjust to low light, ensure that you keep it in a well-lit room with some natural light filtering in. Give your Anthurium a mix of indirect and direct sunlight to maintain its growth. If the plant isn’t blooming during its growing season, it may need more light, so try moving it to a brighter area or provide artificial lighting.

You can also help the plant by ensuring it has proper care, such as:

  • Regular watering, but not over-watering
  • Maintaining a consistent temperature
  • Providing proper humidity levels

Addressing Overly Bright Light

On the other hand, anthuriums can struggle in overly bright light. Too much direct sunlight can cause scorching and dehydration, leading to a less healthy plant. If your Anthurium is exposed to too much light, you may notice the following signs:

  • Yellow or brown leaves
  • Wilting or drooping
  • Scorched spots on foliage

To address this issue, move your Anthurium to a location with less direct sunlight. Use sheer curtains or blinds to help filter the sunlight if it is too intense. Keep in mind that areas with a southern exposure are the warmest, followed by eastern and western exposures, while northern exposure is the coolest.

Remember, the key to healthy Anthurium growth is finding a balance between low and bright light. Maintaining the right light conditions will result in a lush and vibrant plant that brings a touch of the tropics to your home.

Caring for Anthurium

Anthuriums are stunning houseplants known for their vibrant, heart-shaped flowers and waxy leaves. However, it’s essential to understand the specific light requirements and other factors to keep them thriving.

Watering Requirements

Anthuriums prefer consistent soil moisture, but it is crucial to avoid over-watering. You should water your Anthurium when the top inch of soil starts to feel dry. A well-draining potting mix will help prevent root rot and ensure healthy plant growth. Remember to reduce watering frequency during winter months, as the plant’s water intake typically decreases during this period.


To promote healthy growth and flowering, it is important to provide regular fertilization for your Anthurium. Use a balanced, water-soluble fertilizer at half strength every month during the growing season. It’s best to apply the fertilizer after watering to prevent root burn and ensure optimal nutrient uptake by the plant. During the dormant winter months, reduce the frequency of fertilization.

Temperature and Humidity Considerations

Maintaining the ideal temperature and humidity levels is vital for Anthuriums’ overall health. These plants thrive in temperatures ranging from 65-85°F (18-29°C) and do not tolerate cold drafts or sudden temperature fluctuations well. Ensure the plants are not exposed to temperatures lower than 60°F (15°C) as this may lead to slow growth and potential damage.

Humidity is another crucial factor for thriving Anthuriums. They prefer a moderately humid environment, around 60% relative humidity or higher. You can maintain humidity around your Anthurium by using a humidifier, placing the plant on a tray filled with pebbles and water or occasionally misting the leaves with water.

Implementing these care guidelines regarding watering, fertilization, and temperature and humidity will significantly contribute to a healthy and thriving Anthurium plant in your home.

Frequently Asked Questions

Best indoor location for Anthurium?

To grow Anthurium plants indoors successfully, place them in a spot that receives bright, indirect light. These plants thrive in environments with 500-1000 footcandles (fc) of light but can adapt to lower light levels if necessary. You can use a light meter to accurately measure the light intensity to fulfill their needs. Avoid placing them under direct sunlight as it may cause sunburn and dehydration.

Full sun or shade for Anthurium?

Anthurium plants prefer bright, indirect sunlight over full sun or complete shade. They can be quite sensitive to excess sunlight which might lead to dehydration and sunburn. On the other hand, if they receive too little light, they become leggy and may not produce flowers. Moderately bright environments are ideal for Anthuriums, giving them just the right balance of light for healthy growth.

Anthurium under artificial light?

Anthurium plants can grow under artificial light as long as they receive appropriate light levels of 15-100 μmol/m²/s in PPFD (Photosynthetic Photon Flux Density) values for about 10-12 hours a day. Adequate light ensures steady growth and flowering. When choosing an artificial light source, choose full-spectrum bulbs to mimic natural sunlight and provide the optimal light conditions for your Anthurium.

Best window for Anthurium?

Place your Anthurium near an east-facing window to provide them with bright, indirect light. Alternatively, a west or south-facing window can also work if you ensure the plant is placed away from direct sunlight, possibly filtered through sheer curtains or blinds. The goal is to maintain a balance between the intensity of light – not too bright or too dim.

Low light vs bright light?

Anthurium plants grow best in bright indirect light compared to low light environments. You want to ensure they receive at least six hours of bright, indirect light each day for optimal growth and flowering. While they can tolerate low light conditions, they may exhibit slower growth and reduced blooming under such circumstances. Monitor your plant – if it’s growing slowly or not flowering, it may need more light.

Anthurium different species lighting?

Although there are many Anthurium species, they generally share similar lighting requirements. They need bright, indirect sunlight to thrive and produce flowers. Adjusting the light levels based on species-specific requirements may be necessary, but generally, following the guidelines for Anthurium light requirements will help keep the plants healthy across various species. Keep in mind the seasonal changes and their impact on the available natural light.
