What can excessive nitrogen fertilizer cause in nursery plants?

Excessive nitrogen fertilizer can lead to excessive leaf growth and poor flowering in nursery plants. Nitrogen is a vital nutrient that promotes vegetative growth and contributes significantly to the development of foliage. However, when nitrogen levels are too high, plants tend to prioritize leaf production over flowering and fruiting. This phenomenon occurs because when plants receive an abundance of nitrogen, their energy and resources are directed towards leaf development instead of reproductive structures, which can result in a lack of blooms or reduced flower quality.

In addition, such imbalances can create a scenario where the plant has lush green foliage but may not have adequate strength or energy to support flowering, leading to fewer flowers and potentially poorer quality blooms. Balancing nitrogen with other nutrients is essential for optimal flowering and overall plant health.

While excessive nitrogen might lead to other issues such as possible increased susceptibility to diseases or nutrient imbalances, the primary and most direct impact is observed in the plant's ability to produce flowers effectively.
