Why does your Petunia Opera Supreme Raspberry Ice IMP have leggy stems? Diagnose the cause and fix it with our step-by-step guide.
Petunias are sun-loving plants that require at least 6 hours of direct sunlight; low light levels trigger etiolation, where stems stretch excessively to reach a light source.
A lack of available nitrogen prevents sturdy cell wall development, resulting in weak, elongated growth and pale green foliage in 'Opera Supreme' varieties.
Excessive moisture in the substrate can lead to soft, succulent growth that lacks structural integrity, often accompanied by weakened stem tissue.
Extreme heat can accelerate growth rates beyond the plant's ability to support its own weight, leading to spindly, leggy structures in summer months.
