Mow your lawn when it needs it, not just because a set day has arrived. In Sydney, lawns often need more frequent mowing while actively growing in warmer months and less during cooler weather. The right timing depends on your grass type, recent rain, temperature and how quickly the lawn is growing.

A simple check is to look at the grass before each mow. If it has grown enough to need a cut, mow it while you can still remove only a small amount. Turf Australia advises removing no more than one-third of the grass height in a single mow. Its lawn care guide explains that mowing frequency varies by turf type.

What affects how often you should mow?

Grass type makes a difference: lawns can respond differently to the same conditions. Growth also changes with the weather. Warm, rainy periods may mean the lawn needs attention sooner; during cooler or drier spells, growth may slow.

Use the grass itself as your guide. Check whether it has grown beyond the height you want and whether a normal cut would remove too much at once. If the lawn has become very long, bring it back gradually over several cuts instead of scalping it in one go.

Seeded Grounds’ lawn care guide covers general mowing and lawn care. This article focuses on adjusting your mowing routine through the Sydney seasons.

A seasonal mowing guide for Sydney

Spring

As conditions warm and the lawn begins growing more actively, check it more often. You may need to mow more frequently than in winter, but let growth—not the calendar—set the timing. Keep the mower at a suitable height for your grass type.

Summer

Continue checking the lawn as it grows. Heat and dry conditions can affect growth, so don’t assume every lawn needs the same weekly schedule. Avoid cutting too much at once, and follow Sydney Water’s current Water Wise Guidelines if you water your lawn. The rules set out permitted times and methods for using drinking water outdoors.

Autumn

Keep mowing while the grass is still growing, then allow more time between cuts as growth slows. In its autumn lawn care advice, ABC Gardening Australia shares seasonal tips with a turf expert from Turf Australia. The advice notes that couch, kikuyu and buffalo are warm-season grasses that can go dormant over winter.

Winter

Many lawns grow more slowly in cooler weather, so you may be able to mow less often. Don’t rely on a fixed “stop mowing” date: check whether your grass is still growing and mow when it needs it. The amount of growth can vary between lawns and seasons.

A simple routine to follow

Walk around the lawn before mowing and check how much it has grown. If a regular cut would remove more than one-third of the grass height, reduce the height over more than one mow. In spring and summer, check the lawn more often; in autumn and winter, let the slower growth guide the gap between cuts.

For a very overgrown lawn, a one-off tidy may be more suitable than trying to cut it short at once. Regular mowing can then help keep it manageable. Seeded Grounds lists lawn mowing, edging and ongoing or one-off outdoor maintenance among its services. seededgrounds.com.au

Frequently asked questions

Should I mow my lawn every week in Sydney?

Not necessarily. Weekly mowing may suit a lawn that is growing quickly, but grass type and weather affect how soon it needs another cut. Check its growth rather than following a fixed schedule.

Should I stop mowing in winter?

Not on a set date. If the lawn is still growing and needs a cut, mow it. If growth slows, you may need to mow less often.

What if my lawn has grown too long?

Avoid cutting it very short in one go. Reduce the height gradually over several mows, following the one-third guideline.
