Rationales (2026/2027)
Section 1 — General Landscape Knowledge, Safety & Design
1. What is the primary purpose of a site analysis before beginning a landscape
installation?
A. Determine the cheapest plants available
B. Identify site conditions that affect the design and installation
C. Select fertilizer brands
D. Determine the client's favorite colors
Correct Answer: B
Rationale: A site analysis identifies important conditions such as sunlight,
drainage, soil, utilities, existing vegetation, slopes, access, and environmental
constraints. These factors determine which plants, materials, and construction
methods are appropriate.
2. Which factor is most important when selecting a plant for a specific location?
A. Nursery price
B. Plant availability only
C. Compatibility with site conditions
D. Container color
Correct Answer: C
Rationale: Plants should be matched to available sunlight, soil, moisture,
temperature, mature size, and other site conditions. Choosing plants solely
because they are inexpensive or attractive often results in poor establishment.
,3. What does the principle of balance describe in landscape design?
A. Equal plant prices
B. Distribution of visual weight
C. Identical plant heights
D. Equal irrigation pressure
Correct Answer: B
Rationale: Balance is the distribution of visual weight within a landscape. It may
be symmetrical or asymmetrical and helps create visual stability.
4. Which design element primarily guides the eye through a landscape?
A. Line
B. Soil
C. Fertilizer
D. Drainage
Correct Answer: A
Rationale: Lines created by paths, walls, plant beds, fences, and other features
direct visual movement and can create formal or informal circulation patterns.
5. What is a focal point in landscape design?
A. An area deliberately emphasized to attract attention
B. The lowest point on a site
C. The irrigation control valve
D. The property boundary
Correct Answer: A
Rationale: A focal point provides visual emphasis. Examples include specimen
trees, sculptures, fountains, architectural features, or particularly attractive plant
groupings.
,6. Which design principle helps make different landscape elements appear
visually related?
A. Unity
B. Erosion
C. Compaction
D. Infiltration
Correct Answer: A
Rationale: Unity creates a sense that individual elements belong together.
Repeated colors, forms, textures, materials, and plant groupings can help establish
unity.
7. What should normally be identified before excavation begins?
A. Customer's favorite plant
B. Underground utilities
C. Fertilizer brand
D. Mowing schedule
Correct Answer: B
Rationale: Underground utilities can create serious safety hazards and costly
damage. Utility locations should be determined before excavation.
8. What is the purpose of calling 811 before digging?
A. Order landscaping materials
B. Locate underground utilities
C. Schedule irrigation
D. Obtain fertilizer
Correct Answer: B
Rationale: The 811 system is used to request utility locating before excavation.
Workers should wait for the appropriate markings and follow applicable
requirements.
, 9. Which PPE is particularly important when operating loud landscape
equipment?
A. Hearing protection
B. Sandals
C. Loose jewelry
D. Cotton gloves only
Correct Answer: A
Rationale: Equipment such as mowers, chainsaws, blowers, and trimmers can
generate damaging noise. Appropriate hearing protection reduces occupational
noise exposure.
10. What is the safest approach to a damaged electrical power tool?
A. Use it carefully
B. Tape the cord and continue
C. Remove it from service until repaired
D. Give it to another worker
Correct Answer: C
Rationale: Damaged electrical equipment can cause shock, burns, or fire. It should
be removed from service and properly repaired or replaced.
11. When lifting a heavy landscape material, the worker should primarily:
A. Bend at the waist
B. Keep the load close and lift with the legs
C. Twist while lifting
D. Lift rapidly
Correct Answer: B
Rationale: Keeping a load close to the body and using the legs reduces stress on
the back. Twisting while lifting increases injury risk.
