Red Seal Program

The Red Seal Landscape Horticulturist Interprovincial (IP) exam is the national journeyperson certification for landscape horticulturists in Canada, administered through the Red Seal Program and provincial apprenticeship authorities. The exam has 120 multiple-choice questions, requires 70% to pass, and typically allows about four hours. It is built on the Red Seal Occupational Standard (RSOS), covering safety and common skills, soils and plant science and plant identification, plant installation and establishment, hardscape construction (retaining walls, paving, drainage), turf and planting maintenance with IPM, and irrigation, grading, and equipment. Provincial exam fees generally range from about $100 to $170 CAD. This free prep includes 100 research-based practice questions with explanations and an AI tutor.

Sample Red Seal Landscape Horticulturist Practice Questions

Try these sample questions to test your Red Seal Landscape Horticulturist exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1On a landscape job site, what does a WHMIS Safety Data Sheet (SDS) primarily provide to a worker handling a herbicide concentrate?
A.The retail price and supplier discount schedule
B.Hazard identification, safe handling, first aid, and personal protective equipment information
C.The recommended mowing height for treated turf
D.A warranty certificate for the chemical container
Explanation: Under WHMIS 2015, a Safety Data Sheet provides standardized hazard information including identification, first-aid measures, handling/storage, and required PPE. Workers must review the SDS before handling any controlled product such as a pesticide concentrate. This protects against exposure and ensures proper emergency response.
2When operating a walk-behind rotary mower on a slope, which practice best reduces the risk of slipping under the deck?
A.Mow up and down the slope so the operator stays above the machine
B.Mow across the slope (along the contour) rather than up and down
C.Disengage the blade-control bail while moving downhill
D.Remove the discharge chute deflector for better visibility
Explanation: Walk-behind mowers should be operated across the face of a slope, along the contour, so the operator does not slip beneath the deck and feet stay clear of the blade. Mowing up and down increases the chance of the mower rolling back onto the operator. Ride-on mowers reverse this rule and are driven up and down slopes.
3A trench 1.5 m deep is being dug to install a drainage line in sandy soil. According to general occupational health and safety practice in Canada, what is the primary protective measure required before a worker enters?
A.Spraying the trench walls with water to bind the soil
B.Sloping, shoring, or shielding the trench walls
C.Covering the trench bottom with landscape fabric
D.Posting a single warning sign at the property entrance
Explanation: Excavations and trenches deep enough to expose a worker (generally 1.2 m or more) must be protected against cave-in by sloping the walls back, installing shoring, or using a trench shield/box. Soil type affects the required slope angle. Cave-ins are a leading cause of fatalities in excavation work.
4Before any mechanical excavation begins on a residential landscape project, which step is legally required in Canada to avoid striking buried utilities?
A.Request a locate from the provincial one-call utility locating service
B.Dig a small test pit only if the homeowner remembers where lines are
C.Assume all utilities are at least 1 m deep and dig normally
D.Notify the municipal parks department
Explanation: Workers must contact the one-call locate service (for example Ontario One Call or BC 1 Call) before excavating so buried gas, electrical, water, and communication lines are marked. Striking a utility can cause injury, death, and major liability. Locates are free and legally required prior to ground disturbance.
5Which type of hearing protection is generally required when operating a backpack blower or string trimmer for extended periods?
A.No protection is needed for handheld equipment
B.Hearing protection (earplugs or earmuffs) because noise exceeds 85 dBA
C.Only a dust mask is required
D.Safety glasses alone are sufficient
Explanation: Backpack blowers and string trimmers commonly produce noise above the 85 dBA action level, so hearing protection such as earplugs or earmuffs is required to prevent noise-induced hearing loss. Eye and respiratory protection are also recommended but do not replace hearing protection. Prolonged exposure above 85 dBA causes permanent damage.
6A landscape crew must move a 600 kg boulder with a skid-steer and lifting chains. What is the most important rigging consideration?
A.Use the longest possible sling to reduce the angle
B.Ensure the rated working load limit of the slings and shackles exceeds the load and account for sling angle
C.Attach the chain to the bucket cutting edge for a low centre of gravity
D.Lift quickly to minimize time under load
Explanation: Rigging hardware must have a working load limit (WLL) that exceeds the load, and the load on each leg increases as the sling angle from horizontal decreases. A qualified worker selects slings and shackles rated for the load and configuration. Overloading or shallow sling angles can cause catastrophic failure.
7What does a binomial botanical name such as Acer rubrum consist of?
A.Family name and common name
B.Genus name and specific epithet
C.Cultivar name and trademark
D.Order and class
Explanation: Under binomial nomenclature, a plant's scientific name is made of the genus (capitalized) followed by the specific epithet (lowercase), both italicized, for example Acer rubrum (red maple). This standardized Latin-based system identifies plants unambiguously worldwide. A cultivar name, when present, is added in single quotes after the species.
8A soil test reports 40% sand, 40% silt, and 20% clay. Using the soil texture triangle, what is this soil's textural class?
A.Sandy clay
B.Loam
C.Silty clay
D.Sand
Explanation: A soil with roughly balanced sand and silt and a moderate clay fraction (about 40/40/20) falls into the loam class on the USDA soil texture triangle. Loam is prized in landscaping because it combines good drainage, aeration, and moisture/nutrient retention. Texture is determined by the relative percentages of sand, silt, and clay.
9At what soil pH range are most plant nutrients generally most available to landscape plants?
A.3.5 to 4.5
B.6.0 to 7.0
C.8.5 to 9.5
D.10.0 to 11.0
Explanation: Most landscape plants and turfgrasses grow best, with nutrients most available, in slightly acidic to neutral soil around pH 6.0 to 7.0. Below this range some nutrients become more soluble to toxic levels (and others tie up), while strongly alkaline soils lock up iron, manganese, and phosphorus. Acid-loving plants like rhododendron prefer the lower end.
10Which soil property describes a soil's capacity to hold and exchange positively charged nutrient ions such as calcium, magnesium, and potassium?
A.Bulk density
B.Cation exchange capacity (CEC)
C.Porosity
D.Field capacity
Explanation: Cation exchange capacity (CEC) measures a soil's ability to hold exchangeable cations (Ca, Mg, K, NH4) on clay and organic matter surfaces, which buffers nutrient supply to plants. Soils high in clay and organic matter have high CEC and retain nutrients well. Sandy soils have low CEC and leach nutrients quickly.
