1Which of the following is a warm-season turfgrass commonly used in southern climates?

A.Kentucky bluegrass

B.Bermudagrass

C.Tall fescue

D.Perennial ryegrass

Explanation: Bermudagrass (Cynodon dactylon) is a warm-season grass thriving in hot climates with strong heat and drought tolerance. It is widely used in southern lawns and golf courses.

2What is the scientific name for Bermudagrass?

A.Poa pratensis

B.Cynodon dactylon

C.Zoysia japonica

D.Stenotaphrum secundatum

Explanation: Cynodon dactylon is the scientific name for Bermudagrass, a popular warm-season turfgrass. Knowing the scientific name helps professionals communicate accurately about grass species.

3Which warm-season grass is known for its deep rhizome system and extreme shade tolerance?

A.Zoysia

B.Centipede grass

C.Bahia grass

D.St. Augustine grass

Explanation: Zoysia is a warm-season grass with deep rhizomes that provide excellent drought tolerance and can grow in partial shade better than most warm-season alternatives. It is denser than centipede and bahia grasses.

4St. Augustine grass (Stenotaphrum secundatum) is most tolerant of which condition?

A.Drought stress

B.Shade

C.Cold temperatures

D.Sandy soils

Explanation: St. Augustine grass is a warm-season grass that tolerates shade better than most warm-season species. It thrives in coastal areas and warm, humid regions with partial shade.

5Which cool-season grass is known for its fine texture and shade tolerance?

A.Bermudagrass

B.Fine fescue

C.Zoysia

D.Bahia grass

Explanation: Fine fescue is a cool-season grass with thin, fine leaf blades that performs well in shaded and acidic soils. It is ideal for northern shade lawns.

6What is the scientific name for Kentucky bluegrass?

A.Lolium perenne

B.Poa pratensis

C.Festuca arundinacea

D.Agrostis alba

Explanation: Poa pratensis is the scientific name for Kentucky bluegrass, a cool-season grass widely used in northern climates. It self-repairs through rhizome growth.

7Tall fescue (Festuca arundinacea) is best suited for which climate?

A.Hot, humid tropics

B.Warm deserts

C.Cool to transitional zones

D.Polar regions

Explanation: Tall fescue is a cool-season grass with drought tolerance that performs well in transitional and cool climates. It has deeper roots than Kentucky bluegrass, making it suitable for drier regions.

8Which grass species is characterized by its fine, needle-like leaves and low mowing height tolerance?

A.Perennial ryegrass

B.Bentgrass

C.Tall fescue

D.Kentucky bluegrass

Explanation: Bentgrass (Agrostis) has fine, needle-like leaves and can tolerate mowing heights as low as 0.125 inches, making it ideal for golf greens and premium sports fields.

9Centipede grass is primarily used in which region due to its low maintenance requirements?

A.Northern United States

B.Coastal mid-Atlantic

C.Southeastern United States

D.Northwestern United States

Explanation: Centipede grass is a warm-season grass popular in the southeastern U.S. for its low fertilizer and maintenance requirements. It grows well in acidic, sandy soils.

10Which of the following is NOT a cool-season turfgrass?

A.Perennial ryegrass

B.Bahia grass

C.Bentgrass

D.Fine fescue

Explanation: Bahia grass is a warm-season grass adapted to low-fertility soils in the southeastern U.S. Perennial ryegrass, bentgrass, and fine fescue are all cool-season grasses.

About the NALP LCT Exam

The NALP Landscape Industry Certified Lawn Care Technician credential validates entry- to mid-level lawn care technicians on the core agronomic, pest, and pesticide-safety knowledge required to manage residential and commercial turf. Candidates study NALP's Lawn Care Technician body of knowledge spanning turfgrass identification, cultural practices, IPM, and pesticide calibration. The exam is then delivered online through ProctorU as two scored sections that must each clear a 70% threshold. Passing both sections earns the Landscape Industry Certified (LIC) designation maintained through NALP recertification.

Assessment

100 multiple-choice questions split across Section 1 (turfgrass, cultural practices, fertilization, irrigation) and Section 2 (pest, weed, disease management, pesticide safety, calibration). Candidates must score 70% or higher on each section to pass.

Time Limit

Not officially published; ProctorU session typically allows ample time to complete each section

Passing Score

70% or higher on each of two sections

Exam Fee

$300 full exam; $50 per-section retake (plus ProctorU fees) (National Association of Landscape Professionals (NALP))

NALP LCT Study Tips from Top Performers

1Overprepare turfgrass ID for both warm-season and cool-season species so you can identify them by leaf and growth habit.

2Memorize EPA signal words (Caution, Warning, Danger) and the structure of FIFRA pesticide labels.

3Drill the calibration formula GPA = 5940 × GPM / (MPH × W) until you can rearrange it without thinking.

4Learn the major turf disease pathogens paired with their preferred hosts and weather conditions.

5Differentiate pre-emergent vs post-emergent herbicide timing relative to soil temperature and weed lifecycle.

6Know recommended mowing heights and the 1/3 rule for each common warm- and cool-season species.

7Practice IPM scouting thresholds so you can justify when to treat versus when to monitor.
