Brisbane's summer isn't like most of the country's. Between the humidity and the wet season downpours, grass can put on serious growth in a matter of days — which is exactly why so many lawns get away from homeowners between December and March.
How often, by grass type
- Buffalo (the most common Brisbane lawn): Every 1–2 weeks in summer, stretching to 3–4 weeks in winter.
- Couch: Weekly during peak summer growth, it's fast-growing and looks patchy quickly if left.
- Kikuyu: Similar to couch, weekly in summer, and needs a firm edge to stop it invading garden beds.
- Zoysia: The slowest grower of the common types, every 2–3 weeks is usually enough, even in summer.
Why the "one-third rule" matters more in summer A good rule of thumb year-round is never cutting more than a third of the blade length in one go. In summer this matters even more, a lawn that's gone three weeks without a cut and then gets scalped back to its usual height is far more likely to yellow off and struggle, especially in the heat. If your lawn has gotten away from you, it's often better to bring the height down gradually over two mows a few days apart rather than one hard cut.
Signs you're mowing too infrequently
- Grass seed heads appearing (a sign it's stressed and trying to reproduce)
- Visible unevenness a day or two after mowing
- Thatch build-up at the base of the lawn
- Weeds getting a foothold in thin patches
What this means for your mowing schedule Most of our Brisbane clients move to a fortnightly schedule through summer and drop back to monthly over winter. If you're finding your current schedule leaves the lawn looking overgrown before the next visit, it's usually a sign the frequency needs adjusting for the season rather than a problem with the mowing itself.
