What does the term "flagging" refer to in plant health?

The term "flagging" specifically refers to the wilting or drooping of branches or stems in plants. This phenomenon often indicates stress or a health issue within the plant, such as insufficient water, disease, or pest infestation. Observing flagging can be crucial for diagnosing problems and determining appropriate interventions to restore the plant’s health.

While other options may relate to various aspects of plant care, none align with the definition of flagging. Marketing plants, color changes in leaves, and the application of fertilizers do not capture the specific condition of wilting or drooping associated with the term. Understanding this distinction is essential for effective plant management and care.
