Insights · Seasonal planning
The short answer. Melbourne grounds run on two speeds. Grass and hedges grow hard from September to April, then slow right down from May to August. A good maintenance program follows that curve: more frequent visits and growth control through the warm months, structural work and lower frequency through winter. Here's what that looks like season by season, and why a flat weekly schedule overpays in July and falls behind in November.
How Melbourne's growing year works
Melbourne sits in a temperate climate with a genuine four-season cycle, and the grounds respond to two drivers: soil temperature and rain. The warm-season lawns that dominate common property in the south-east, mainly kikuyu and couch, surge with warmth from October to March and nearly stop over winter. Cool-season grasses such as rye and fescue, and lawns in heavy shade, do the opposite: they flush in spring and autumn and struggle through summer heat.
Weeds arrive in two waves for the same reason. Summer weeds germinate as the soil warms in spring, and winter weeds germinate as it cools in autumn, which is why preventative weed treatment is timed twice a year rather than sprayed at whatever comes up. Rainfall follows its own pattern: winter and spring are reliably wetter, while summer swings between dry spells and storm bursts. A well-run program is built around all of this rather than around a fixed day of the week.
Spring (September to November): the flush
Spring is the busiest stretch of the grounds year. Mowing steps up as growth takes off, moving from fortnightly toward weekly on high-presentation sites. The first main hedge trim happens once the spring flush has pushed and hardened, so the cut holds its line instead of disappearing in a fortnight. The spring window for preventative weed treatment opens before the soil fully warms, heading off the summer weeds before they show. Feeding resumes with growth, mulch is topped up before the heat arrives so beds hold their moisture, and irrigation is recommissioned and test-run before the first hot week, not during it.
Spring is also when a neglected winter shows. Catch-up pruning, bed resets and edge definition are best done early in the season, because everything done in September pays presentation dividends until autumn.
Summer (December to February): heat management
Summer mowing continues at growing-season frequency, but the cutting height lifts. A slightly longer leaf shades the soil, holds moisture and keeps warm-season lawns greener through hot spells, where a scalped lawn browns off in days. Growth pulses with rain and pauses in heatwaves, so a good operator reads the site rather than cutting for the sake of the visit. Watering, where irrigation exists, works best deep and infrequent rather than a daily sprinkle, and beds mulched in spring need far less of it.
Storm cleanup becomes part of the rhythm after wind events. And late summer opens the second preventative weed window: February into early autumn is when treatment goes down ahead of the winter weeds, including winter grass, that germinate as the soil cools. One honest note for committees: some browning on warm-season lawn in extreme heat is normal, and it recovers with autumn rain. Chasing a mid-January bowling green on an unirrigated site wastes money.
Autumn (March to May): the second flush and the leaves
Autumn rain brings a second growth flush, so mowing frequency holds before it tapers late in the season. On any site with deciduous trees, leaf drop becomes the visit-defining task, and the priority is paths, drains and gutters more than the lawns themselves: wet leaves on paving are a slip risk, and blocked drains show up as flooding in the first winter downpour. An autumn feed strengthens turf before the cold, and it's the season to oversow or repair cool-season and shaded lawns while the soil is still warm enough to strike.
The final hedge shaping of the year sits in mid to late autumn. Growth has nearly stopped, so a clean cut now holds its edge right through winter.
Winter (June to August): structure and reset
Growth slows and visit frequency stretches out, typically to fortnightly or monthly, but the work doesn't stop. Litter, paths, beds and winter weeds still need attention, and winter grass is now the main weed pressure on lawns. Winter is the structural window: deciduous trees and roses are pruned while dormant, with July the traditional month for roses in Melbourne. Bed edging and definition work shows best against slow growth, and disruptive or machinery-heavy jobs suit the quieter months on occupied sites.
Winter is also the planning season. Budgets, scopes and contractor decisions for the new growing year are best settled before September arrives, and if the contract is going to market, this is the time. Our guide to tendering a grounds maintenance contract covers how to scope it.
What this means for the budget
Seasonality is the reason fixed monthly fees exist in grounds maintenance. The contractor averages the heavy spring and summer months against the light winter ones, and the committee or owner gets one predictable number for the year. A flat weekly schedule priced per visit overpays through winter; a purely hourly arrangement makes summer unpredictable.

Common questions
How often should common property be mowed in Melbourne?
Through the growing season, roughly September to April, weekly to fortnightly depending on the lawn type and the presentation standard the site wants. Through winter, fortnightly to monthly is usually enough. The right program follows growth rather than the calendar alone.
When should hedges be trimmed in Melbourne?
The two main trims that hold shape longest are after the spring flush and again in mid to late autumn. Fast growers may need a mid-summer pass as well. Avoid hard cuts during extreme heat, which stresses the plant and browns the face of the hedge.
When is the best time to prune trees and roses in Melbourne?
Deciduous trees and roses are pruned in winter while dormant, and July is the traditional month for roses in Melbourne. Be aware that significant trees, including many on common property, can be protected by local council rules, so check whether a permit is needed before any major tree works.
