Excessive Nitrogen Fertilization

A high-nitrogen fertilizer promotes rapid vegetative growth but lacks the structural support needed for strong cell walls. This results in lush, green foliage accompanied by weak, elongated stems.

Common

Water Stress (Fluctuating Moisture)

Inconsistent watering cycles can cause the plant to undergo rapid growth spurts followed by periods of stress. These erratic growth phases often lead to weakened, spindly stem development.

Common
