Why Do Anthurium Flowers Turn Green? We Explain Why and Tell You How to Fix It!

Anthuriums, known for their vibrant and long-lasting flowers, might face issues such as flowers turning green. Here’s why and how to fix it:

1. Hormones and Light Exposure:

  • Wholesalers sometimes add hormones to force Anthuriums to flower early. Once at home, the plant reverts to its natural growth cycle, causing flowers to wither.
  • Anthurium prefers filtered or reflected light over direct sunlight on its leaves. Placing it in a room with natural light but away from south- or east-facing windows is advisable.

2. Nitrogen Content:

  • Green flowers can result from an excess of nitrogen. Anthuriums prefer a diet rich in phosphorus, so avoiding nitrogen fertilizer is recommended.

Common Maintenance Mistakes:

  • Watering Errors: Anthuriums are sensitive to watering. It’s better to underwater than overwater. Use non-hard water, preferably rainwater or room-temperature water with added vinegar for hard tap water.
  • Humidity Maintenance: Maintain humidity by placing a bed of gravel in water under the pot and spraying non-calcareous water on the leaves.
  • Root Health: Avoid permanent dampness in the substrate to prevent root rot and fungal issues.
  • Pest Control: Watch for pests like mealybugs, as they can affect Anthurium health.

Bonus Tips:

  • Cut off spent flowers to stimulate the plant for new shoots.
  • Remove dust from leaves to improve light exposure and photosynthesis.
  • Repot every two years to prevent overcrowding and refresh the soil.
  • In spring and summer, use special Anthurium fertilizer or a universal liquid fertilizer for indoor plants.

Taking care of Anthuriums involves maintaining proper watering practices, providing suitable light conditions, and addressing any nutrient imbalances. With these tips, you can enjoy vibrant and healthy Anthurium flowers in your indoor space.
