How Often Should You Mow Your Lawn in Sydney?

Mowing frequency in Sydney's south-west isn't a fixed number — it follows how fast the grass is actually growing, and that changes a lot between a humid January and a cold July morning in Ruse.

A season-by-season guide

• Spring (Sep–Nov): growth takes off. Weekly to fortnightly is usually right.
• Summer (Dec–Feb): warm-season grasses like buffalo and couch grow fast with storms and humidity — fortnightly at minimum, weekly if you like it short.
• Autumn (Mar–May): growth slows. Every two to three weeks is generally enough.
• Winter (Jun–Aug): many Macarthur lawns barely grow. Monthly, or as needed to tidy up.

The one-third rule

Never take off more than about a third of the leaf in a single cut. Scalping a lawn stresses it, opens gaps for weeds and leaves it looking brown for weeks — particularly on buffalo, which is common right through Campbelltown.

Signs you've left it too long

• Clumps of clippings sitting on the surface after a cut
• Yellow or straw-coloured lawn immediately after mowing
• Weeds flowering and setting seed above the grass line

If your lawn has already got away from you, it's usually better to bring it back over two cuts a week apart rather than one hard scalp.
