Turf 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. Establishment can be by seed, sod, sprigs or plugs; each has different timing, water and soil contact requirements. Know seedbed preparation, sowing rate, and the importance of soil contact and moisture for germination.
Maintenance covers mowing (the one-third rule), fertilising (timing and rate by species and season), irrigation (deep and infrequent), aeration, dethatching, topdressing and overseeding. Understand turf health indicators: colour, density, uniformity, thatch depth and root depth. Learn the difference between thatch and mat, and why excess thatch blocks water and air. Pest, disease and weed management in turf follows integrated principles.
Traps: cutting too short (scalping); watering lightly and often; fertilising at the wrong time of year; and confusing thatch with soil. Questions often test the one-third rule and seasonal timing.
Worked rule of thumb: never remove more than one-third of the leaf blade in a single mow. If the grass is overgrown, mow in stages rather than scalping. Water deeply to encourage deep roots, and aerate when compaction or thatch limits infiltration.
