CPH Landscape Design and Installation Flashcards

Which plant spacing pattern creates the most naturalistic appearance in a landscape planting?

Staggered or triangular plant spacing mimics natural plant distribution and produces a more organic, naturalistic appearance than rigid rows or grids.

What is the primary function of 'edging' in a landscape?

Answer: To define clean borders between lawn and planting areas

Edging defines the crisp boundary between different landscape areas—such as lawn and planting beds—and prevents grass encroachment.

In landscape design, a 'focal point' is best described as:

Answer: A prominent design element that draws the viewer's attention and anchors the composition

A focal point is a dominant element—such as a specimen tree, sculpture, or water feature—that attracts the eye and organizes the surrounding composition.

What is the recommended planting depth for most trees and shrubs at installation?

Answer: With the root flare at or slightly above finished grade

Trees and shrubs should be planted so the root flare is visible at or slightly above grade, preventing crown rot and girdling root development.

The horticultural '1/3 rule' states that during any single pruning event you should remove no more than:

Answer: One-third of the plant's total foliage or canopy

The 1/3 rule advises removing no more than one-third of a plant's total foliage at one time to avoid excessive stress and inhibited regrowth.

The phrase 'right plant, right place' is a core horticulture principle that means:

Answer: Selecting plants naturally adapted to the specific site conditions of the planting location

Right plant, right place means choosing plants whose natural requirements match the site's soil, moisture, light, and climate conditions, reducing the need for supplemental inputs.
