Red Seal Landscape Horticulturist study guide
Red Seal Landscape Horticulturist · Work through your exam, one topic at a time.
The Red Seal Landscape Horticulturist credential is an interprovincial trade certification for people who build, plant, and maintain landscapes - installing hardscape and softscape, assessing sites, amending soil, selecting and planting ornamentals and turf, and carrying out ongoing cultural and integrated pest management work. It is aimed at apprentices and working horticulturists who want a nationally recognized endorsement of journeyperson-level competence, and it is also used by employers and clients as a signal of consistent, safe, trade-standard practice. The Red Seal Landscape Horticulturist study guide has 10 sections and about 4,171 words.
01Occupational Skills and Safety
The Occupational Skills and Safety domain tests whether you can work legally, safely and systematically on a Canadian landscape site. Expect questions on field-level hazard assessment, workplace hazardous materials, personal protective equipment, ergonomics and manual lifting, utility locates, limits of approach to energized conductors, trenching and confined spaces, and emergency response.
440 words, about 2 min02Tools and Equipment
The Tools and Equipment domain tests selection, safe operation, maintenance and troubleshooting of hand tools and power equipment: pruners and saws, chainsaws, string trimmers, hedge trimmers, mowers, blowers, aerators, tillers and compact utility loaders. Questions often hinge on the small details that separate a technician from a labourer: which cutter suits live wood, what happens when two-stroke and four-stroke fuel get swapped, and how a chain is filed.
425 words, about 2 min03Site Assessment and Planning
The Site Assessment and Planning domain tests your ability to gather site facts before anything is designed or built: reading drawing sets and survey information, measuring slope and drainage, identifying microclimates, checking bylaws and setbacks, inventorying existing trees, and turning a client's wish list into a program, budget and phased plan. Check every sheet for scale, north arrow, legend, benchmark and contour interval.
432 words, about 2 min04Soil, Growing Media, and Plant Nutrition
The Soil, Growing Media, and Plant Nutrition domain tests how you judge a growing medium, interpret a soil test, and feed plants without creating new problems. Expect questions on texture and structure, compaction, pH and cation exchange capacity, organic matter and topsoil specification, mulches and composts, and fertilizer calculations and timing.
433 words, about 2 min05Plant Identification, Selection, and Use
The Plant Identification, Selection, and Use domain tests whether you can name a plant correctly, describe its requirements, and place it where it will still fit in twenty years. Questions cover botanical nomenclature, hardiness and site matching, native and invasive status, mature size, and the design principles that make a planting read as intentional rather than accidental.
401 words, about 2 min06Planting and Installation
The Planting and Installation domain tests whether a plant goes into the ground so that it establishes quickly and survives: nursery stock handling, hole preparation, root flare depth, backfill, watering, mulching, staking, timing and spacing. Most exam scenarios are about a detail done slightly wrong that kills the plant two seasons later.
429 words, about 2 min07Maintenance and Cultural Practices
The Maintenance and Cultural Practices domain tests the routine decisions that keep a landscape healthy: pruning method and timing, turf mowing, aeration and overseeding, irrigation, fertilizing by soil test, mulching and winter protection. Questions reward knowing why a practice is done, because the same cut made at the wrong time of year causes a different outcome.
405 words, about 2 min08Plant Health and Integrated Pest Management
The Plant Health and Integrated Pest Management domain tests diagnosis and decision-making rather than spraying. Expect questions on the IPM sequence, the disease triangle, distinguishing abiotic from biotic problems, monitoring and thresholds, biological controls, and the legal and safety rules that come with a pesticide label.
393 words, about 2 min09Hardscape and Landscape Construction
The Hardscape and Landscape Construction domain tests whether you can build paving, walls, steps and edges that stay flat, plumb and drained through Canadian freeze-thaw cycles. Questions focus on base preparation, compaction, drainage, reinforcement, frost depth and the details that cause failures two or three winters later.
410 words, about 2 min10Communication, Documentation, and Customer Relations
The Communication, Documentation, and Customer Relations domain tests the business side of horticulture: written scopes, change orders, daily records, invoicing, warranties and the conversations that prevent disputes. Exam questions often present a realistic client situation and ask what a professional should have done in writing, and when.
