Lawn care check list for Sydney’s residents
Checklist on lawn care
A scruffy lawn undoes a lot of work everywhere else — however good the house looks, the front yard is what people see first. The good news is that keeping a Sydney lawn genuinely good is not a big job. It's a small job done at the right times, and almost all of the effort is concentrated into two short windows a year.
Most lawn advice you'll find online is written for the northern hemisphere: snow damage, crabgrass pre-emergents, dormant winters. None of that applies here. This checklist is built for Sydney's actual calendar — warm-season grasses, a growth surge from September, humid summers, and a mild winter where the grass stops but the weeds don't.
Tick as you go

Pick a season and work down the list. It remembers what you've ticked, so you can come back to it — and it opens on whatever season Sydney is actually in right now.
Weekly lawn Tasks
Nobody wants to lose a weekend to the lawn, and you don't have to. Through the growing season the whole weekly routine is about twenty minutes, and four things.
Watering
One deep soak beats a daily sprinkle every time. A light watering every evening wets the top centimetre, so the roots stay there and the first run of hot days cooks them. Water deeply once or twice a week instead and the roots chase the moisture down, which is what carries a lawn through February. Do it early in the morning — watering in the middle of the day mostly waters the sky, and watering at night leaves the leaf wet for hours, which is how fungal problems start in a Sydney summer. Sydney Water's water-wise rules point the same way: hoses and irrigation before 10am or after 4pm.
The morning after you water, push a screwdriver into the lawn. If it slides in easily to 100 mm, the water got where it needed to. If it stops at 30 mm, you're watering the top of the soil and nothing else.
Mowing
Set the height before you start, and never take off more than a third of the leaf blade in one cut. In spring and early summer that means mowing every seven to ten days — sometimes every five when it's really running — rather than letting it get away and scalping it back. Sharp blades matter more than most people think: a blunt mower tears the grass instead of cutting it, and the torn tips brown off within a day.
Weeding
Walk the lawn once a week with a weeding tool and pull whatever's appeared, root and all — snapping the top off just tells it to try again. Doing it weekly takes two minutes; doing it twice a year takes an afternoon and a bag of herbicide. It's also a chance to pick up sticks and stones before the mower finds them.
Edging
Edging is what makes a lawn look professionally maintained rather than just cut. Run a line trimmer or edging shears along the paths, driveway and garden beds after mowing, and keep the boundary between lawn and mulch crisp. It's the single cheapest thing you can do for kerb appeal — and it's included in every one of our mowing visits.
Repairs:
Dog patches, worn tracks and bare spots want dealing with while they're small. Loosen the surface, add a little topsoil or a lawn patching mix, press in seed or a plug of runners from elsewhere in the lawn, and keep it damp until it takes. Warm-season grasses repair fastest from October to March, when they're actively running — patching in July mostly just feeds the birds.
The number that matters most
How high to set the mower
More Sydney lawns are ruined by cutting too short than by anything else. Longer leaf means deeper roots, more shade on the soil, less water lost and fewer weeds — because weed seed needs light to germinate, and a thick lawn doesn't give it any.
Lawn mowing strategies by season
The whole year on one page
Darker means "this is the month to do it". The big jobs — aeration, top-dressing, the main feed — all cluster in spring, because that's when a warm-season lawn is growing hard enough to recover fast.
Checklist for Your Spring Lawn Care Schedule
Spring is the important one. A warm-season lawn wakes up around September and spends the next three months growing harder than it will all year, which means it can repair, thicken and recover from almost anything you throw at it. Work done now returns tenfold; the same work done in June mostly doesn't take.
Spring Lawn Care checks
Get the gear ready first — sharpen or replace the mower blades, check the oil and fuel, and make sure the line trimmer actually runs before the grass takes off. Then, in order: scalp or lower the first cut slightly to clear the winter thatch and let light in, feed with a complete lawn fertiliser, aerate if the soil is compacted, top-dress and level any hollows, and patch the bare spots while the runners are moving. Water it all in properly.
A soil test is worth doing once if the lawn has never really thrived — it's often a pH problem rather than a feeding problem, and no amount of fertiliser fixes that.
Summer
Summer is maintenance, not projects. Mow higher, water deeply and early, and resist the urge to feed heavily in the worst of the heat. Keep an eye out for the two things Sydney summers bring: brown patch and other fungal problems in humid weeks, which airflow and morning watering prevent better than any spray; and lawn grubs, which show up as patches that lift like carpet in late summer.
Autumn
Growth slows but doesn't stop, and this is the second feeding window. An autumn fertiliser goes into root growth rather than leaf, which is exactly what you want going into the cold. Keep mowing — less often, and slightly lower as the light drops. Clear fallen leaves off the lawn rather than letting them mat, because a week under wet leaves will yellow a patch.
Winter
The grass is idle; the weeds are not. Bindii, winter grass and clover all run through the cold months, and bindii in particular is worth treating in June or July — long before the prickles appear, which is when everyone actually notices it. Mow every three to five weeks to keep things even, stay off the lawn when it's soggy, and leave the fertiliser and the aerator in the shed until spring.
Almost every lawn problem in Sydney traces back to one of three things: cut too short, watered too often and too lightly, or never fed at all.

Questions
Sydney lawn care questions
How often should I water my lawn in Sydney?
Once or twice a week, deeply, rather than a little every day. A deep soak drives roots down; light daily watering keeps them in the top centimetre where they cook in the first hot spell. Water early in the morning — Sydney Water's rules put hoses before 10am or after 4pm anyway, and morning watering lets the leaf dry, which prevents fungal problems.
What height should I cut a Sydney lawn?
Buffalo at 40 to 50 mm through summer and around 30 mm in winter; kikuyu 25 to 40 mm; couch 15 to 30 mm. Higher is safer than lower in every case — longer leaf means deeper roots, less water loss and fewer weeds, because weed seed needs light to germinate.
When should I fertilise?
Twice a year covers most lawns: a complete fertiliser in early spring as growth starts, and a second application in early autumn that feeds the roots going into winter. A light feed in early summer helps a hard-working lawn, but avoid heavy feeding in the peak of the heat, and skip it entirely in winter when the grass can't use it.
When is the right time to aerate?
Spring, and really only spring. Aeration and top-dressing both stress the lawn briefly, so they need to be done when the grass is growing hard enough to fill back in quickly. September through November is the window. Aerating a dormant winter lawn just leaves holes.
How do I get rid of bindii before it prickles?
Treat it in winter, June or July, while it's still a small flat rosette. By the time you can feel the prickles in spring, the seed has already set and you've lost the year. A bindii-specific treatment applied in the cold months, followed by keeping the lawn thick enough to crowd it out, sorts it within a season or two.
Why does my lawn have brown patches in summer?
Three common causes. Fungal disease, which shows up in humid weeks and is helped by watering in the morning rather than at night and by improving airflow. Lawn grubs, where the affected patch lifts like loose carpet because the roots have been eaten. And simple scalping — taking too much off in one cut, which browns the lawn within a day or two.
Can I repair bare patches myself?
Yes, and it's easier than most people expect between October and March while the grass is actively running. Loosen the surface, add a thin layer of topsoil or patching mix, press in seed or a plug of runners taken from a thicker part of the lawn, and keep it damp until it establishes. In winter it mostly won't take.
Is it worth paying someone to do all this?
The weekly part — mowing, edging, a quick weed — is what most people hand over, because it's the bit that has to happen every week regardless of weather or weekend plans. The seasonal jobs are easy to do yourself with this checklist. We're happy to do either; our mowing service includes edging, blowing down and taking the clippings away.
