Why does your Anthurium andraeanum Bianco have leggy stems? Diagnose the cause and fix it with our step-by-step guide.
Anthuriums are shade-tolerant but require bright, indirect light to maintain structural integrity. Low light levels trigger 'etiolation,' where the plant rapidly elongates its petioles in an attempt to reach a light source, resulting in weak, floppy stems.
A diet too high in nitrogen relative to potassium can promote rapid, succulent vegetative growth. This fast-tracked development often results in soft, elongated tissues that lack the structural strength to support the weight of the white spathes.
Stagnant air around the foliage can prevent the plant from transpiring effectively, leading to heavy, water-laden stems that lack rigidity. This is often accompanied by a lack of mechanical stress which helps strengthen stem cells.
