What is often the site of injury in ornamental plants damaged by equipment?

Injuries to ornamental plants caused by equipment commonly occur on the lower trunk or stems. This area is more vulnerable because it is typically at the height where equipment, such as lawn mowers or string trimmers, operates. When contact is made with these parts of the plant, it can result in physical damage that affects the plant's overall health and stability.

The lower trunk and stems are crucial for supporting the plant and transporting water and nutrients. Damage in this area can lead to issues such as nutrient deficiencies, susceptibility to pests and diseases, and even death of the plant if the injury is severe. Recognizing this common site of injury emphasizes the importance of caution when operating equipment around ornamental plants, allowing for better care and management of these plants.

Meanwhile, the other choices involve parts of the plant that are less likely to experience equipment-related damage in direct contact situations. For example, upper leaves are higher up and less exposed to low-lying equipment, while roots are typically protected underground. Flower petals are also less susceptible to physical damage from equipment since they are often above the operating height.
