What is the expected outcome after repeatedly destroying regrowing herbaceous perennials?

When dealing with herbaceous perennials, the expected outcome of repeatedly destroying their regrowing shoots is that no new shoots will develop. This is because many perennials have a strong regenerative ability and can often survive initial cutting or removal. However, with continuous management efforts aimed at controlling their growth, such as frequent cutting or mowing, the energy reserves in their root systems can deplete over time. This persistent interference can lead to reduced vigor, ultimately resulting in the plant being less able to produce new shoots as it exhausts its resources.

While the other choices may seem plausible, they do not accurately reflect the biology of herbaceous perennials under these circumstances. For instance, complete removal within one season (first option) is generally unrealistic due to the established root systems of perennials which may allow them to recover. Additionally, thriving due to stress (third option) conflicts with the ecological principle that stress usually hampers growth rather than enhances it. The need for fertilization (fourth option) also typically contradicts the context, as fertilization is not generally necessary when managing such growth through repeated removal; in fact, unwanted fertilization could exacerbate the situation by encouraging more growth.
