Cert III Horticulture study guide
Cert III Horticulture · Work through your exam, one topic at a time.
The Certificate III in Horticulture (AHC30722) is an Australian nationally recognised vocational qualification for people working, or preparing to work, in horticulture: nursery production, landscape and garden maintenance, parks and gardens, turf, and related enterprises. It suits apprentices, career changers, and existing workers who want a formal credential for skills they already use, and it is delivered by registered training organisations rather than by a single central examining board. The Cert III Horticulture study guide has 10 sections and about 2,876 words.
01Workplace Safety and Environmental Sustainability in Horticulture
Safety in horticulture starts with recognising that the hazards change with the task, the season and the site. Candidates must understand the hierarchy of control (eliminate, substitute, isolate, engineer, administrate, then PPE as the last line), because questions often describe a control and ask where it sits.
296 words, about 1 min02Plant Identification
Plant identification is a skill built on systematic observation. Candidates should understand botanical nomenclature: genus capitalised, species lowercase, cultivar in single quotes, and the difference between a species, a hybrid (×) and a cultivar.
273 words, about 1 min03Plant Selection, Botany and Plant Selection
Successful planting begins with matching the plant to the site, not the other way around. Candidates must understand the environmental factors that drive plant performance: climate (hardiness zone, frost, heat), light (full sun, part shade, deep shade), soil (texture, pH, drainage, salinity), water availability, wind exposure and microclimate.
260 words, about 1 min04Soil, Growing Media and Plant Nutrition
Soil is a living system of mineral particles, organic matter, air, water and organisms. Candidates must understand texture (sand, silt, clay) and structure (aggregates, pores), because these control drainage, aeration and root growth.
276 words, about 1 min05Plant Propagation and Nursery Production
Propagation is either sexual (seed) or asexual (vegetative). Candidates must understand seed biology: dormancy types (physical, physiological, morphophysiological), scarification (mechanical, chemical, hot water), stratification (cold moist), and the conditions for germination (moisture, temperature, oxygen, sometimes light).
255 words, about 1 min06Planting, Transplanting and Establishment
Planting success depends on preparation, technique and aftercare. Candidates must understand site preparation: weed control, soil improvement, drainage checks, and marking out.
266 words, about 1 min07Pruning, Training and Plant Maintenance
Pruning is controlled wounding for a purpose: health, safety, form, flowering or fruiting. Candidates must understand plant response: apical dominance, auxin, adventitious buds, and how cuts stimulate or suppress growth.
259 words, about 1 min08Turf Establishment and Maintenance
Turf management combines species selection, establishment and ongoing maintenance. Candidates must understand turfgrass types (cool-season versus warm-season), their growth habits (rhizomes, stolons, bunch), and shade, wear and drought tolerance.
250 words, about 1 min09Pest, Disease and Weed Management
Integrated pest management (IPM) is the framework: prevention, monitoring, thresholds, and a hierarchy of controls from cultural and physical to biological and, last, chemical. Candidates must understand the difference between pests, diseases and disorders (abiotic problems such as nutrient deficiency, frost or herbicide damage).
226 words, about 1 min10Irrigation and Water Management
Efficient irrigation matches water delivery to plant need and soil capacity. Candidates must understand soil water: field capacity, permanent wilting point, available water, and infiltration rate.
