If your lawn's looking patchy, thin or slow to green up right now, you're not alone — it's the most common call we get this time of year. Spring in South East Queensland is when subtropical grasses like buffalo, couch and zoysia come out of their slower winter growth and start pushing hard again, and the first few weeks of that growth largely set the tone for how the lawn looks right through summer.
Why spring matters more here than a mowing schedule alone suggests
Unlike cooler climates where lawns have one clear growing season, SE Queensland lawns slow down over winter rather than going fully dormant, then ramp back up quickly once soil temperatures climb in September and October. That fast ramp-up is exactly when weeds, thin patches and compacted soil from winter foot traffic show up most obviously — the grass is trying to recover and fill in gaps at the same time weeds are doing the same thing, and whichever gets ahead first tends to stay ahead.
The checklist
1. Mow high, and mow only once the lawn is actively growing again. Scalping a lawn too early in spring, before it's properly growing, slows recovery rather than speeding it up. Once you're seeing consistent new growth, raise the mower height slightly — a taller cut encourages deeper roots and shades out weed seedlings before they establish.
2. Deal with bare and thin patches now, not in January. Spring is the best window to topdress and overseed or turf-patch bare areas, since the warm, humid growing conditions ahead give new grass the best chance to establish before the peak heat of December–February stresses it.
3. Aerate compacted areas. High-traffic paths, areas near gates, and anywhere water pools after rain are usually compacted. Aerating lets water and nutrients actually reach the roots instead of running off — worth doing before you fertilise, not after.
4. Fertilise once, not repeatedly, to start. A single application of a balanced, slow-release lawn fertiliser once the lawn is actively growing is usually enough to kick spring growth along. Over-fertilising early, before root systems are active, tends to feed weeds as much as it feeds the lawn.
5. Get on top of weeds while they're small. Broadleaf weeds and bindii are far easier to manage in early spring while they're still small than once they've flowered and set seed. If bindii was a problem last summer, spring is the window to break that cycle.
6. Check your irrigation before the dry heat arrives. Spring is usually drier than the wet season that follows, and it's the easiest time to walk the yard and check sprinklers, timers and dry spots before you're relying on the system through a heatwave.
When it's worth calling a professional instead of DIY-ing it
A lawn that's thin from lack of mowing height or a missed feed usually recovers fine with the steps above. It's worth bringing in a professional when you're dealing with large bare areas that need proper turf or seed matching, drainage issues that keep waterlogging the same spots, an infestation (armyworm and lawn grubs both show up hard in SE Queensland once the weather warms, often overnight), or when a property simply needs to look presentable on a deadline — a rental turnover, a real estate listing, or getting ready for visitors.
That last one is worth flagging specifically for landlords and property managers: spring is also the start of the real estate selling and leasing season across the Sunshine Coast, Moreton Bay and North Brisbane, and a lawn that's been left over winter is one of the fastest things to undercut a property's street appeal in listing photos.
