Excessive Nitrogen Fertilization

An overabundance of nitrogen-rich fertilizer promotes rapid, succulent vegetative growth at the expense of structural strength and flowering, leading to weak, floppy stems.

Common

How to confirm: Review your recent fertilization schedule to see if high-nitrogen organic or synthetic fertilizers were used.

Lack of Pruning

How to confirm: Check if you have pinched back the terminal buds during the early growing season to encourage branching.

Overwatering

Consistently damp soil can lead to weakened root systems, reducing the plant's ability to support its own weight and resulting in soft, elongated growth.

Common
