Climatic Conditions for Anthurium

Before welcoming an Anthurium into your home, it’s crucial to acknowledge its preference for specific climatic conditions. Thriving in environments with very high temperatures and ample humidity, this plant requires careful consideration to provide the optimal setting for its growth and development.

Potting Soil Preferences: A Foundation of Peat

Anthuriums thrive in peat-based potting soil, offering the ideal foundation for their roots to flourish. Understanding the significance of proper soil composition is key to fostering a healthy and vibrant Anthurium.

Finding the Perfect Spot for Anthurium

Selecting the right location for your Anthurium is crucial for its well-being. Opt for a spot that is sheltered from drafts, offering bright but indirect sunlight. Striking a balance between light exposure and protection from drafts is essential for maintaining the plant’s vitality.

Protecting Anthurium from the Cold

Anthuriums are sensitive to cold temperatures, with a minimum requirement of 15°C / 60°F in winter. Due to this, keeping the plant outdoors during the winter season is impractical. Learn how to safeguard your Anthurium from harsh weather conditions and temperature fluctuations, ensuring its survival during the colder months.

How Often to Water Anthurium

Maintaining the right level of hydration is critical for Anthuriums. Water generously and consider placing expanded clay in the saucer to enhance humidity. Adjusting watering frequency based on environmental conditions, particularly during hot weather, ensures the plant receives the moisture it needs for optimal growth.

How to Tell if Your Anthurium Needs Water

Detecting when your Anthurium requires watering is an essential skill for any plant parent. While yellowing leaves are an early indicator, a more reliable method involves physically assessing the soil. Insert your finger at least 2 cm deep into the soil to determine its moisture level, helping you gauge when it’s time to quench your Anthurium’s thirst.


Fertilizing Anthurium

To keep your Anthurium thriving, adopt a fertilization routine. From spring to September, fertilize every 15 days using natural liquid fertilizer diluted in irrigation water. In autumn and winter, reduce the frequency to once a month.

Pruning Anthurium

Unlike many plants, Anthurium does not require regular pruning. Simply remove dry leaves when necessary. Note: Anthurium can be toxic to cats; refer to photos for identification.

How long does Anthurium last?

With optimal care, Anthurium can endure for many years, rewarding you with its vibrant presence. Its blooms can last between two and three months

Multiplying Anthurium

The recommended method for propagation is division by heads. Follow these steps:

  1. Wet the potting soil thoroughly.
  2. Gently pull the plant out, holding it by the basal part to avoid damaging roots.
  3. Separate sections with 3-5 leaves each.
  4. Plant each seedling in a pot with a mix of peat, flower potting soil, and sand (proportions: 3:2:1).
  5. Place pots in well-lit areas, misting the plants every three days.

Taking Anthurium Cuttings

Alternatively, take small plant portions and place them in a pot with a mix of 3 parts peat and 1 part universal soil. Press gently, water, and keep the seedlings in a room with at least 24°C, spraying them every 3-4 days to maintain humidity.

Repotting Anthurium

Repot your Anthurium every 2-3 years or when it outgrows its current pot. The ideal time for repotting is spring.

Blooming Anthurium

With optimal conditions, Anthurium can bloom year-round, with a peak during summer lasting a couple of months. Provide support for stems as they may droop due to the weight of flowers.

How to make your Anthurium bloom again

In addition to proper soil and watering, here’s how to stimulate new flowers:

  1. Place the plant in an area with diffuse light and high humidity.
  2. Maintain a temperature above 18°C / 64°F.
  3. Use fertilizer rich in phosphorus and potassium.

How to achieve red flowers

Achieving vibrant red flowers in Anthuriums, particularly the A. Andreanum variety, involves cultivating them in well-drained soil. Ensure the soil remains consistently moist, avoiding waterlogging to promote the distinctive red hue.


To achieve the captivating red blooms unique to the A. Andreanum variety, cultivate Anthuriums in well-drained soil, ensuring a consistently moist environment without waterlogging. Maintain the plant in an environment with temperatures ranging between 20°C and 27°C  / 68°F and 81°F for optimal growth.

Finally, during the growing season, approximately every 5 weeks, provide the Anthurium with organic fertilizer to enhance its overall health and encourage abundant flowering.

Hydroponic Cultivation of Anthurium

For those interested, Anthurium can also thrive in hydroponics. When adopting this method, it’s crucial to use demineralized or rainwater. Alternatively, mineral water from standard bottles is suitable. If tap water is preferred, ensure it’s not overly calcareous, and consider letting it stand for 24 hours before use.

How to deal with the most frequent issues

Addressing common issues with Anthurium leaves: stains, browning, cleaning, and yellowing.

Why Anthurium Flowers Turn Brown

The occurrence of browning, particularly in winter, can be attributed to several factors. Common causes include the use of excessively cold water and improper exposure—such as placement in cold environments, darkness, or drafts.

Spotted Leaves

If your Anthurium’s leaves show unsightly spots, it’s likely due to the presence of mealybugs. Remove them manually using tweezers and follow up with an effective pest control solution. A mixture of Marseille soap and 1 liter of water is a recommended remedy.

Brown Stains on Anthurium Leaves

Brown stains typically signal an excess of fertilizer. To rectify this, water the plant more generously than usual. This helps flush out accumulated salts in the soil, alleviating the problem.

Cleaning Anthurium Leaves

Maintain the cleanliness of your leaves by spraying them with lukewarm, low-lime water. Allow the leaves to air dry naturally, but avoid exposing them to drafts during the drying process.

Removing Dried Anthurium Leaves

Examine the leaves for insights into your plant’s health:

  • Dry, discolored leaves may indicate excessive direct sunlight. Adjust the plant’s placement to a location with lower light intensity.
  • Premature leaf fall suggests low temperatures; relocate the Anthurium to a more suitable spot.
  • If leaves wilt and dry after flowering, it’s a natural process. Trim them using sanitized scissors.

Addressing Yellow Anthurium Leaves

Yellowing leaves can have various causes, depending on where the yellowing occurs:

  • All-yellow leaves indicate potential root rot due to persistent overwatering. Adjust watering habits to avoid water stagnation.
  • If there are numerous yellow leaves, the plant may be exposed to excessive wind. Relocate the pot to a less windy area.
  • Yellowing at the leaf edges may signify dehydration or over-fertilization. Adjust watering frequency and consider reducing fertilizer application.


How to treat Anthurium diseases

Let’s now see how to manage the primary adversaries—pests and diseases—plaguing this plant and explore effective methods to counteract them.

  • Root Rot: Root rot, a fungal ailment disrupting leaf development, often arises from water stagnation. To tackle this issue, allow the substrate to thoroughly dry out or, for a more comprehensive solution, repot using fresh soil and include marbles or drainage material at the base. If the disease is advanced, intervention becomes challenging.
  • Red Spider Mite: These tiny mites, residing beneath leaves, announce their presence through delicate webs and yellowing leaves. Combat them with soft soap sprayed under the leaves, alternating with white mineral oil to counteract their eggs.
  • White Mealybug and Shield Mealybug: Combat these small white insects by manually removing them, wiping affected areas with an alcohol-soaked cotton ball, or applying white mineral oil to the plant. Repeat this treatment 2-3 times at three-week intervals.
  • Anthracnose: Originating from fungi, anthracnose manifests as round, dark, dry spots. Poor air circulation is often the cause. Remove the most affected leaves, and administer a suitable fungicide that spreads throughout the plant from the leaves.
  • Grey Mold: This fungal ailment forms grayish mold at stem bases due to excessive and frequent watering. Address environmental conditions by allowing the soil to completely dry before watering. Improve ventilation, thin the plant by removing older stems, and apply a broad-spectrum fungicide every 20 days until the issue resolves.

Anthurium as a Gift

Anthurium, symbolizing love and friendship, makes a meaningful gift. Often presented during the Christmas season, it outlasts and requires less maintenance than the traditional poinsettia.

The spadix’s association with Cupid’s arrows in ancient Greek culture adds a special symbolism to this cherished flower.

How much does an Anthurium plant cost

The cost of an Anthurium plant can vary widely based on factors such as the plant’s size, variety, age, and the seller’s pricing policies. On average, you can expect to pay anywhere from $20 to $50 for a standard-sized Anthurium plant. Larger or more unique varieties, especially those with larger or rare-colored blooms, may be priced higher, ranging from $50 to $100 or more.
