- Must Have Maintenance, a Melbourne lawn care company completing over 15,000 jobs annually, warns that preparation work carried out in September and early October has a greater impact on summer lawn performance than anything done once the growing season is underway.
- Melbourne's warm-season grasses — couch, buffalo, and kikuyu — emerge from winter dormancy when soil temperatures reach 18 degrees, typically in late September to early October, making this the optimal window for core aeration to relieve winter compaction and improve root health.
- Fertilising in early October provides slow-release nitrogen that sustains growth through the critical eight to twelve weeks before summer, whereas lawns fertilised in November are left catching up during the hottest months of the year.
- Irrigation systems must be calibrated to operate within Victoria's permanent water-saving hours of 6pm to 10am before summer arrives, as systems not adjusted in advance are both inefficient and non-compliant.
- Founder Lukas James states that lawns which receive aeration, feeding, and irrigation calibration in September consistently outperform those where the window is missed, and that repairing the consequences of skipping pre-spring preparation typically takes most of the summer to address.
MELBOURNE, Australia — 06 October 2026 — Must Have Maintenance, a Melbourne garden and lawn maintenance company completing more than 15,000 jobs per year, says the decisions made about lawn preparation in September and early October have a greater impact on summer performance than anything done after the growing season begins, and that the clients calling in November because their lawn has already deteriorated are almost always paying more for a worse result than a pre-spring visit would have produced.
Melbourne's warm-season grasses, couch, buffalo, and kikuyu, come out of winter dormancy as 18-degree soil temperature, typically in late September to early October. That transition is the window in which the preparation work has the highest impact. Winter compaction, where soil has been compressed by foot traffic and rainfall over the cooler months, restricts the oxygen, water, and nutrient flow to roots that the lawn needs to establish strong growth before the heat arrives. Core aeration, the process of removing small plugs of soil to relieve compaction, is most effective done annually in spring before the growth flush begins, not after it is already underway.
Fertilisation in the first week of October, once the lawn has begun coming out of dormancy, provides the slow-release nitrogen feed that sustains growth across the critical eight to twelve weeks before summer. A lawn fertilised in early spring carries that nutrition through to December. A lawn that missed the window and was fertilised in November is playing catch-up through the hottest months of the year. Irrigation calibration is the third element: Victoria's permanent water-saving rules restrict watering to between 6pm and 10am, which means a system not adjusted to run in those hours before summer is both inefficient and non-compliant. Must Have Maintenance reviews irrigation scheduling and adjusts run times at the start of each spring visit.
"By the time someone calls us in November because their lawn is patchy and struggling, the window to prepare it properly has closed. We can treat the symptoms but we cannot recover the growth that should have happened in October. The lawns that look the best through December and January are the ones where we went in during September: aerating the compaction, feeding the soil before it needed it, and calibrating the irrigation before the first hot week. That sequence takes half a day. Undoing the damage from skipping it takes most of the summer," said Lukas James, founder of Must Have Maintenance.
