Anthurium andraeanum Dorado Yellow Leaves - Causes & Fixes

error

Overwatering and Root Rot

Anthuriums require well-draining media; excessive moisture suffocates the roots, leading to oxygen deprivation. This causes the chlorophyll to break down, manifesting as yellowing leaves, often starting with older foliage.

Very Common

How to confirm: Gently lift the plant from its pot to check if the roots are dark brown and slimy instead of firm and white.

1 Immediately stop watering and allow the soil to dry out completely to prevent further oxygen deprivation to the roots.

Nutrient Deficiency (Nitrogen or Magnesium)

The 'Dorado' cultivar requires consistent fertilization during its growth phase. A lack of nitrogen causes uniform yellowing of older leaves, while magnesium deficiency often presents as chlorosis between leaf veins.

Very Common

How to confirm: Check if the yellowing is spreading from the leaf edges inward or if the veins remain dark green.

Low Humidity or Environmental Stress

As tropical plants, Anthuriums thrive in high humidity; dry indoor air can cause physiological stress. This stress disrupts metabolic processes, leading to leaf yellowing and potential crisping of the margins.

Common

How to confirm: Use a hygrometer to check if your ambient humidity is consistently below 50%.

1 Increase local humidity around the plant by using a pebble tray or a humidifier to prevent leaf margins from crisping.

Light Intensity Stress (Photo-oxidation)

While 'Dorado' needs bright light, direct afternoon sun can cause leaf bleaching and yellowing. Excessive light intensity damages the photosynthetic apparatus of the fleshy Anthurium leaves.

Common

How to confirm: Observe if the yellow patches appear specifically on parts of the leaves that receive direct sunlight.

1 Move your Anthurium to a location with bright, indirect light, away from direct afternoon sun rays to prevent further leaf bleaching.

2 If the plant is in a spot with insufficient light during cloudy periods, supplement with a full-spectrum grow light to maintain healthy photosynthesis.
