Late winter is when most lawns around Narangba look their worst. Thin in the shady spots, a bit yellow, maybe a bare patch where the trampoline sat all year. That’s normal. Buffalo and couch both go semi-dormant over winter and only start actively growing again once soil temperatures climb back above about 18 degrees, which for us is usually late August into September. Whatever work goes in over the next few weeks decides how the lawn looks by Christmas.
Soil First, Grass Second
Most spring lawn problems trace back to the soil, not the grass. Compacted or acidic soil won’t hold onto fertiliser no matter how much you put down. A basic pH test kit takes ten minutes and tells you whether you need lime this spring or whether you’re fine to go straight to feeding. Most Narangba soils run acidic, so it’s worth checking rather than assuming.
Dethatch If It Feels Spongy
Walk on the lawn. If it feels soft and bouncy rather than firm underfoot, there’s a thatch layer building up between the soil and the green growth, and it’s blocking water and fertiliser from reaching the roots. A dethatcher pulls that layer out and lets the lawn breathe again. Do this before fertilising, not after; there’s no point feeding a lawn that can’t absorb it. We’ve got push and petrol dethatchers in stock, and scarifiers available through Hire Equipment if you’d rather not own one.
High-traffic spots, paths, anywhere a trailer’s been parked, are worth aerating at the same time. Even a garden fork pushed in every 15cm and rocked back and forth makes a difference on a small lawn.
Feed To The Grass Type
Buffalo and couch have different nitrogen needs, so check the bag before you buy. Buffalo (Sir Walter, Palmetto and similar) handles a slow-release, lower-nitrogen fertiliser better; it scorches easily if you overdo the nitrogen in warm weather. Look for a spring formulation with added iron for colour without pushing excessive leaf growth. Couch and kikuyu are more nitrogen-hungry and take a heavier feed without the same scorch risk.
Early spring, once night temperatures sit consistently above 12 to 13 degrees, is the right window for the first feed. A second, lighter application six to eight weeks later carries the lawn into summer. Water it in straight after spreading; granular fertiliser sitting on dry leaf blades in the sun will burn the grass.
Top Dress While It’s Growing
Spring is the best time to top dress because the lawn is putting out new growth fast enough to grow through a light layer of soil instead of getting smothered by it. A sandy loam mix is the standard choice for Queensland lawns, good drainage, won’t compact hard the way a heavier clay-based mix can.
Top dressing is also how you fix low spots and bare patches. Rake it into thin areas about 10 to 15mm deep and water it in; the surrounding runners will fill the gap in a few weeks rather than you needing to relay turf.
Deal With Weeds While They’re Small
Winter grass, bindii and clover are easiest to deal with in early spring, before they set seed and spread. A selective herbicide that targets broadleaf weeds without harming buffalo or couch is the go, though buffalo is sensitive to some weed-and-feed combinations that couch handles fine, so check the label. If you’re not sure which product suits your lawn, bring a photo of the weed in and we’ll point you to the right one. Bindii especially is worth tackling now, before it hardens into the prickly seed heads that make a barefoot backyard a hazard by November.
Raise The Mower Height
Lift the cutting height slightly as growth picks up. Mowing buffalo too short in spring stresses the plant right when it should be building root reserves for summer. As a rough guide, buffalo sits happiest around 50 to 75mm, couch can go shorter at 20 to 35mm. Whatever height you’re at, make sure the blades are sharp; a torn, ragged cut heals slower and looks patchy next to a clean one, and it’s easy to overlook after a mower’s sat idle all winter.
Check The Gear Before The Grass Gets Away From You
Spring is when the mower, whipper snipper and blower all come back out of the shed. Worth sorting before the grass is ankle-high: sharpen or replace the mower blades, mix fresh 2-stroke fuel and check the trimmer line hasn’t perished, do an oil change if the mower’s due one, and check the air filter if it’s been sitting a while. We stock STIHL mowers, blowers and trimmers along with the oil, trimmer line and consumables to keep them running, plus the fertiliser, lime, top dressing and dethatchers to do everything above.
