How Often Should You Mow Your Lawn in Melbourne?
Short answer: In Melbourne, mow weekly during spring and summer, fortnightly in autumn, and every 3–4 weeks (or not at all) in winter. The exact frequency depends on your grass type, rainfall, fertilising and how tidy you want it to look.
There's no single "right" mowing schedule for every lawn — it changes with the season, your grass variety, and the weather that particular week. But Melbourne's climate follows a predictable enough pattern that you can plan your year. This article gives you a clear, local rule of thumb so your lawn stays thick and healthy without you mowing when there's nothing to cut.
Why mowing frequency matters
Mowing is the single biggest influence on how your lawn looks and behaves. Get the frequency right and you get a dense, green, weed-resistant lawn. Get it wrong — either mowing too rarely (letting it get leggy and seed) or too often and too short (scalping) — and you weaken the plant.
The key principle is the one-third rule: never cut more than one-third of the grass leaf height in a single mow. That rule dictates your frequency. When grass is growing fast, you need to mow more often to avoid removing too much at once.
Melbourne's seasonal mowing guide
Melbourne has four distinct lawn seasons. Here's how often to mow in each.
Spring (September–November): weekly
As soil warms and rain returns, warm-season grasses (Buffalo, Kikuyu, Couch) kick into active growth. You'll likely need to mow every 7 days. This is also when you bring the mowing height back down to its normal setting after raising it for winter.
Summer (December–February): weekly (or as growth allows)
Growth is strong early in summer, then slows if it gets hot and dry. Keep weekly mowing while the lawn is actively growing. If your lawn goes dormant in a heatwave, ease off — there's no point cutting grass that isn't growing, and mowing a drought-stressed lawn damages it.
Autumn (March–May): fortnightly
Growth slows as days shorten and temperatures drop. Every two weeks is usually enough. You'll gradually raise the mowing height slightly toward the end of autumn.
Winter (June–August): every 3–4 weeks, or skip it
Warm-season grasses go dormant and barely grow. Mow only when there's something to cut — often just once a month, sometimes not at all during cold, wet spells. Never mow frosty or waterlogged grass; you'll damage the plant and compact the soil.
Frequency by grass type
Different grasses grow at different rates, which changes your schedule.
| Grass type | Peak season frequency | Off season |
|---|---|---|
| Kikuyu | Weekly (grows fast) | Fortnightly autumn, rare in winter |
| Couch | Weekly (needs frequent mowing for fine finish) | Minimal in winter |
| Buffalo (Sir Walter etc.) | Weekly–fortnightly | Fortnightly autumn, rare in winter |
| Fescue / Rye (cool-season) | Fortnightly–weekly | Slower but still some winter growth |
Kikuyu and Couch are the most demanding — they look best mown frequently and short. Buffalo is more forgiving. Cool-season lawns grow more in the cooler months than warm-season ones, so don't be surprised if a fescue lawn still needs the occasional winter mow.
What changes the frequency?
Beyond the season, three things speed up or slow down growth:
- Rainfall and watering. A watered lawn grows faster and needs mowing more often. A dry lawn slows down.
- Fertilising. A feed in spring gives a burst of growth — expect to mow more frequently for the following 3–4 weeks. See our fertilising guide.
- Recent laying or repair. New turf shouldn't be mown until it's rooted (usually 2–3 weeks). After that, light, frequent mowing encourages it to thicken.
Signs you're mowing at the wrong frequency
Too rarely:
- The lawn gets tall, flops over, and looks uneven after a cut.
- You're removing way more than one-third each time (which stresses the plant).
- Weeds and seed heads get out of control between cuts.
Too often / too short:
- The lawn looks pale, thin or scalped.
- Patches of bare soil appear.
- It browns off quickly in warm weather (shallow roots from stress).
Make mowing easier: the weekly routine
If weekly mowing feels like a lot, the trick is to make it a fixed, quick routine rather than a big weekend chore:
- Keep the mower ready (fuel/electric, clean deck, sharp blade).
- Mow at the same time each week so it becomes habit.
- Alternate your mowing direction each time for a better finish.
- Trim edges every second mow so they never get out of hand.
Or — hand it to a professional. A regular service means your lawn is mowed on the right schedule, at the right height, every time, without you lifting a finger.

FAQ
Is it OK to mow the lawn every week?
Yes — in spring and summer, weekly mowing is ideal for most Melbourne lawns. It keeps the cut light (following the one-third rule) and encourages dense, healthy growth.
Can you mow a lawn too much?
Only if you're cutting it too short. Frequent mowing at the correct height is good for the lawn; frequent mowing too low ("scalping") thins and weakens it.
Should I mow in winter in Melbourne?
Only lightly and only when the grass is actually growing — usually once every 3–4 weeks. Avoid mowing frosty or very wet grass, and never cut warm-season grasses short in winter.
How often should I sharpen my mower blade?
Homeowners: at least once per season, ideally at the start of spring and again mid-summer. A dull blade tears the grass, leaving white tips and opening the plant to disease.
What if my lawn has grown really long — can I just cut it right down?
No. Bring it down gradually over two or three mows, a few days apart, removing no more than a third each time. Cutting an overgrown lawn back hard in one go can kill patches of it.
