Which describes a border in gardening?

• A. A raised bed that is not surrounded by a wall
• B. A narrow planting bed along the edge of a garden or walkway
• C. An environmental plant disease
• D. Best performed in late spring

Answer: (B)

A border is a narrow planting bed that runs along the edge of a garden or walkway, used to define space and add color, texture, and structure. This description fits best because borders are placed along the edge—between lawn and path or plantings—and are designed to create a clear boundary while providing a transition area with often seasonal plantings or edging plants. They’re typically low-profile and run the length of the edge, making maintenance easier and giving the garden a polished look.

The other ideas don’t describe a border. A raised bed not surrounded by a wall describes a separate raised planting area rather than the edge itself. An environmental plant disease is unrelated to how spaces are defined in a garden, and a statement about timing (late spring) doesn’t define what a border is.
