Insufficient Light Intensity

Anthuriums are shade-tolerant but require bright, indirect light to maintain compact growth. Low light levels trigger 'etiolation,' where the plant stretches its petioles excessively to search for a light source.

Very Common

How to confirm: Observe if the leaves are spaced very far apart on long, thin stems and move the plant closer to a window with filtered light.

Improper Humidity Levels

Low ambient humidity can cause the plant to prioritize rapid, weak stem elongation as it struggles with transpiration stress. This often accompanies dry air common in heated indoor environments during winter.

How to confirm: Use a hygrometer to check if humidity is below 50% and consider using a pebble tray or humidifier.

Excessive Nitrogen Fertilization

An overabundance of nitrogen-rich fertilizer can stimulate rapid, succulent vegetative growth. This results in soft, weak stems that lack the structural integrity to hold heavy leaves upright.

Common

lightbulb

How to confirm: Check your recent fertilization schedule and look for dark green, overly soft foliage accompanying the leggy growth.

1 Flush the soil with plenty of fresh, room-temperature water to leach out excess nitrogen salts from the root zone.

2 Repot the plant in a fresh, well-draining medium to provide a balanced nutrient environment and improve structural support.
