What is true regarding the nitrogen needs of different grass species?

Different grass species indeed have varying nitrogen needs, which is influenced by their growth habits, environmental conditions, and the specific role they play within an ecosystem. For example, cool-season grasses such as Kentucky bluegrass and fescue generally require more nitrogen during their peak growth periods in spring and fall, whereas warm-season grasses like Bermuda and zoysia might have higher nitrogen requirements during the warmer months.

This diversity in nitrogen requirements is essential for proper lawn care and achieving optimal growth and health in different grass types. Incorrect assumptions about uniform nitrogen needs across species can lead to over-fertilization, which can harm the environment, or under-fertilization, which can stunt growth and weaken the lawn's overall vigor. Understanding that different species thrive under different nitrogen conditions allows for more tailored and effective fertilization practices.
