Which component is NOT part of landscape construction?

• A. Soil
• B. Drainage system
• C. Structures
• D. Aesthetic lighting

Answer: (D)

The main idea being tested is which elements are fundamental to building a landscape versus those that are more about finishing touches. Soil provides the growing medium and affects stability and drainage; without good soil, plants struggle and the foundation for any plantings falters. A drainage system is essential to move excess water away, protecting both soil structure and any built features from water damage. Structures—such as walls, steps, patios, and other built elements—create the actual physical framework of the landscape and determine how space is used and supported. Aesthetic lighting, while valuable for usability and atmosphere, is typically considered a design or finishing feature that is added after the primary construction is in place, and it involves electrical work rather than the core construction of the landscape. Therefore, aesthetic lighting is not part of the core landscape construction components.
