Very Common

Excessive Nitrogen Fertilization

Too much nitrogen promotes rapid vegetative growth at the expense of structural stability, resulting in long, weak, and succulent stems that cannot support blooms.

Very Common

Overwatering

Excessive moisture in the substrate can lead to soft, weak cell structures in the stems, making them appear elongated and unable to maintain upright posture.
