Well, it depends on your type of grass, the season, and how fast your lawn is growing. In Brisbane’s warm climate, most lawns need weekly mowing through the peak growing season (October to March) and can stretch to every two weeks or monthly through winter.
Getting the mowing frequency right is one of the simplest things you can do for a healthy lawn. Mow too often at the wrong height and you stress the grass. Leave it too long between cuts and you end up hacking into overgrown grass, scalping the turf, and pulling energy from the root system.
This guide covers the practical mowing schedule for every ALC turf variety across all four seasons in Brisbane and south-east Queensland.
Whether you are a homeowner looking after a backyard buffalo or a tradie managing couch across a commercial site, the numbers below will keep your lawn in the right range.
Why mowing frequency matters
Every time you mow, you put the grass plants under some level of stress. The one third rule is the backbone of good lawn care: never cut more than one third of the leaf blade in a single pass.
Cut too much and the plant pulls reserves from its root system to regrow the leaf. That weakens the roots, opens the door to weeds, and makes the lawn more likely to suffer from drought, heat stress, and diseases.
Regular mowing at the right height does the opposite. It encourages lateral growth, which thickens the turf and helps crowd out weeds. Longer blades shade the soil, keeping it cooler and reducing evaporation. Think of the grass blades as solar panels for the plant. The more leaf you leave, the more energy goes into the root system.
The practical takeaway: mow frequently enough that you never need to take off more than one third, and hold the height at the right level for your variety.
Mowing schedule by turf variety and season
Every type of grass grows at a different rate. Buffalo grass and Zoysia are slower growers. Couch grass and IronCutter push faster, especially in the warmer months.
Sir Walter Buffalo Grass
| Season | Mowing frequency | Recommended height |
| Spring (Sep–Nov) | Every 7–10 days | 35–50 mm |
| Summer (Dec–Feb) | Weekly mowing, every 7–10 days | 35–50 mm, raise to 50–70 mm in shade |
| Autumn (Mar–May) | Every 10–14 days | 35–50 mm |
| Winter (Jun–Aug) | Every 3–4 weeks | 50–70 mm |
Sir Walter is the most popular buffalo grass in the country and a strong pick for Brisbane backyards. It handles sun and up to 70% shade, but it grows faster than Sapphire, so it needs more frequent mowing through spring and summer to keep it tidy and promote thick lateral growth.
In winter, growth slows and you can stretch cuts to monthly. Your neighbours will notice the difference when you keep Sir Walter at the right height year-round.
Sapphire Buffalo
| Season | Mowing frequency | Recommended height |
| Spring (Sep–Nov) | Every 10–14 days | 30–50 mm |
| Summer (Dec–Feb) | Every 7–14 days | 30–50 mm in sun, 50–70 mm in shade |
| Autumn (Mar–May) | Every two weeks | 35–50 mm |
| Winter (Jun–Aug) | Every 3–5 weeks | 50–70 mm |
Sapphire’s slower growth rate means less frequent mowing overall. That is a deal for tradies managing large-area maintenance contracts or homeowners who want a relaxing weekend instead of pushing a mower.
The finer leaf still looks sharp at a lower cut, but raise the height in shaded areas to help it thrive.
Palmetto Buffalo
| Season | Mowing frequency | Recommended height |
| Spring (Sep–Nov) | Every 7–14 days | 30–50 mm |
| Summer (Dec–Feb) | Weekly mowing | 30–50 mm, raise in shade |
| Autumn (Mar–May) | Every 10–14 days | 35–50 mm |
| Winter (Jun–Aug) | Every 3–4 weeks | 50–60 mm |
Palmetto sits in a similar mowing range to Sir Walter. In the peak growing season it needs weekly mowing to prevent the leaf getting away from you. Keep mower blades sharp to get a clean cut on the broader buffalo leaf.
Augusta Zoysia, Empire Zoysia, Nara Native Zoysia
| Season | Mowing frequency | Recommended height |
| Spring (Sep–Nov) | Every 10–14 days | 20–50 mm (sun), 40–60 mm (shade) |
| Summer (Dec–Feb) | Every 10–14 days | 20–50 mm |
| Autumn (Mar–May) | Every two to three weeks | 30–50 mm |
| Winter (Jun–Aug) | Every 4–6 weeks or as needed | 40–60 mm |
Zoysia is the slowest grower in the ALC range. Empire Zoysia in particular needs less frequent mowing due to its slow growth rate. That makes all three Zoysias a low maintenance option for homeowners and a cost-effective choice for commercial sites where you want a quality finish without the weekly schedule. Mow only about one third of the leaf blade to reduce stress on the grass.
Wintergreen Couch
| Season | Mowing frequency | Recommended height |
| Spring (Sep–Nov) | Weekly mowing from early October | 15–30 mm |
| Summer (Dec–Feb) | Weekly, up to twice a week on fast-growing sites in peak conditions | 15–30 mm |
| Autumn (Mar–May) | Every 7–14 days | 20–35 mm |
| Winter (Jun–Aug) | Every 3–5 weeks (dormant periods) | 25–40 mm |
Couch grass is fast. It thrives in full sun and loves Brisbane’s heat, but that fast growth means more frequent mowing through the growing season. If you skip two weeks in summer, you will come back to overgrown grass that is tough to bring back to the right length without scalping.
Keep on top of it weekly and it rewards you with a tight, clean finish. Wintergreen Couch needs 7 to 8 hours of direct sun per day. Not a shade variety. A good option for acreage blocks and open sites with full light.
IronCutter Elite Hybrid Bermudagrass
| Season | Mowing frequency | Recommended height |
| Spring (Sep–Nov) | Weekly from early October | 10–30 mm |
| Summer (Dec–Feb) | Weekly, up to twice a week on professionally managed sports turf | 10–30 mm |
| Autumn (Mar–May) | Every 7–14 days | 15–30 mm |
| Winter (Jun–Aug) | Every 3–5 weeks (goes dormant in the cooler months) | 20–35 mm |
IronCutter is the sports turf pick for full sun, high wear sites across Queensland. It grows fast in the warmer months and can handle a very low cut if you have a reel mower.
For residential lawns, a rotary mower at 20 to 30 mm gives a great finish. It keeps the aesthetics up while protecting the root system from heat stress.
In winter it goes dormant and turns straw-coloured, which is normal. Growth picks up again in early spring.
Seasonal mowing tips for Brisbane
To help you maintain the perfect lawn throughout the year, here are some key seasonal mowing tips and best practices to keep in mind:
Spring (September to November)
Growth kicks in hard from early October as soil temperatures rise. This is when mowing frequency jumps from monthly back to weekly or fortnightly depending on your variety. Start higher after winter and gradually bring the mower down to the right height over a few cuts rather than dropping it in one go. This prevents scalping and reduces stress.
For more on handling the spring growth surge, see ALC’s guide to spring lawn maintenance.
Summer (December to February)
This is peak growing season in Brisbane. So how often should you mow your lawn in summer? Buffalo grass, couch, and IronCutter will all need weekly mowing at minimum. In dry periods or during drought, growth slows and you may stretch to 10 days. But do not skip cuts altogether. Overgrown grass that gets scalped in one heavy mow is worse than a slightly longer lawn.
Mow in the early morning or evening, never in the heat of the day. Mowing in full sun and heat causes extra stress on both you and the grass plants.
For summer-specific lawn care, see ALC’s summer survival kit.
Autumn (March to May)
Growth starts tapering. Gradually raise your mowing height over autumn to leave extra leaf area heading into winter. This helps the grass absorb more light as days shorten and creates a better environment for root health heading into the cooler months.
See ALC’s guide on getting your lawn ready before winter for the full autumn prep schedule.
Winter (June to August)
Warm season grasses go dormant or nearly dormant through Brisbane’s winter. Growth slows right down, but that does not mean you stop mowing completely.
A light trim every 3 to 5 weeks keeps the lawn tidy, prevents the grass from falling over and smothering itself, and stops it becoming a haven for weeds and diseases.
Raise the height to the top of the range for your variety. Longer blades protect roots from frost, retain moisture, and help the grass push through to spring in better health.
For the full winter mowing schedule, see ALC’s guide on why you should still mow your lawn in winter.
Common mowing mistakes that hurt Brisbane lawns
Plenty of homeowners make these errors without realising the damage:
- Scalping. Cutting too short exposes the understory and forces the plant to drain its root reserves. It generally takes weeks to recover and opens up bare ground for weeds.
- Mowing with dull blades. Dull blades tear the grass instead of cutting it cleanly. This creates a brown or tan cast across the lawn and invites fungal diseases. Check and sharpen your mower blades at least twice a year.
- Bagging clippings every time. Light clippings left on the lawn break down quickly and return nutrients to the soil. Only use the catcher when clippings are heavy and wet, or when dealing with a fungal issue. Otherwise let them lie.
For more on mowing basics and the one third rule, see ALC’s guide to the impact of mowing on your lawn.
Connect mowing with the rest of your lawn care
Mowing on its own only gets you so far. A healthy lawn in Brisbane needs mowing, watering, fertilisation, and pest control working together.
- Fertilise in the growing season. A quality slow-release fertiliser in spring and summer fuels the growth that regular mowing shapes. See ALC’s lawn fertiliser range for options across all turf types.
- Water deeply but less often. Deep watering pushes roots down, which helps the lawn handle the stress of regular mowing in hot weather conditions. See how to water your lawn.
- Keep weeds and pests in check. A thick, well-mowed lawn is your best defence, but if weeds or grubs get ahead of you, see ALC’s weed killer range and insecticide options.
- Aerate compacted ground. If mowing and feeding are not giving you results, the soil may be compacted. See ALC’s guide to lawn aeration benefits for Brisbane turf.

People also ask about mowing lawns
To help you quickly find answers to common questions about mowing your lawn, here are some frequently asked questions that cover the essentials of lawn care and maintenance.
How often should I mow my lawn in summer?
Most warm season grasses need weekly mowing through the peak growing season (December to February). Buffalo grass like Sir Walter generally needs cutting every 7 to 10 days. Couch grass and IronCutter may need weekly cuts, or up to twice a week on fast-growing sites. In dry periods or drought, growth slows and you can stretch to 10 days.
What height should I mow buffalo grass?
ALC recommends 35 to 50 mm for Sir Walter in full sun, and 50 to 70 mm in shaded areas. Sapphire and Palmetto buffalo sit in a similar range at 30 to 50 mm in sun. Always follow the one third rule and never remove more than a third of the leaf in one cut.
Can I mow less often in winter?
Yes. Warm season grasses go dormant or nearly dormant in the cooler months. A light trim every 3 to 5 weeks keeps the lawn tidy and prevents it from becoming overgrown or harbouring weeds and diseases. Raise the mower height to the top of the range for your variety to protect roots through the cold.
Does mowing promote a healthier lawn?
Regular mowing at the right height encourages lateral growth, which thickens the turf and helps it crowd out weeds. It also keeps the grass at a height where the leaf can absorb sun without falling over and smothering itself. Pair that with proper watering and fertilisation, and a good mowing schedule becomes the backbone of a healthy lawn.
