Lawn care in Sydney
Sydney has a warm-temperate climate: warm, humid summers, mild winters and rain spread through the year. Warm-season lawns grow strongly from spring to autumn and slow down, without fully stopping, over winter.

Short answer
Sydney lawns are mostly warm-season grasses such as buffalo, couch, kikuyu and zoysia, which grow from spring to autumn and slow down in the mild winter. Feed while the lawn is actively growing, apply a winter grass pre-emergent in autumn, watch for lawn grubs in spring and armyworm in summer, and water deeply within Sydney Water's Water Wise Guidelines.
Sydney is one of the easier places in Australia to grow a warm-season lawn. Summers are warm enough for strong growth, winters are mild enough that lawns slow down rather than shut down, and rain falls through the year. That long season helps a lawn recover from wear, but it also gives weeds, grubs and disease plenty of time.
The biggest Sydney lawn jobs are:
- An autumn pre-emergent for winter grass, applied before it germinates as the weather cools.
- Feeding while the lawn is growing, from spring through to autumn, at the label rate.
- Watching for lawn grubs in late spring and early summer, and armyworm through summer.
- Watering within the rules. Sydney Water’s Water Wise Guidelines apply across Sydney, the Blue Mountains and the Illawarra, and set when and how gardens and lawns can be watered. Check the current guidelines before you set a timer.
Shade is a common problem in established Sydney suburbs with large trees. If your lawn is thinning under trees or along the side of the house, see the growing grass in shade guide before you re-turf.
The Blue Mountains have a cooler climate than the rest of Sydney, closer to LawnMan’s cool and highland zone. Check the Lawn Calendar for your postcode.
Some Sydney lawns, especially in shaded or cooler spots, are cool-season grasses such as fescue, which grow most in autumn and spring. Their timing is different. [CONFIRM: add cool-season grass types to the Lawn Library]

Climate
- Warm, humid summers. Bureau of Meteorology long-term averages for Observatory Hill show a mean January maximum of about 26 °C.
- Mild winters, with a mean July maximum of about 16 °C and a mean July minimum of about 8 °C at Observatory Hill.
- Rain falls through the year, averaging about 1,200 mm, and is somewhat higher from late summer to early winter.
Best grass types for Sydney
A common choice for Sydney family yards. It needs the least direct sun of the main warm-season grasses, but use only herbicides whose label lists buffalo.
Hard-wearing and quick to recover in full sun. It needs at least 5 hours of direct sun a day and edging to keep it out of garden beds.
Fast-growing and very hard-wearing in sunny yards, but needs frequent mowing and edging in the warm months.
Dense and slow-growing, so it needs less mowing once established, but recovers slowly from heavy wear.
The lawn year in Sydney
Lawns get going from early spring. Feed once growth is strong, deal with bindii before it forms burrs, check sprinklers with a catch-cup test, and lift a piece of turf to check for lawn grubs from late spring.
Water deeply and less often within the Water Wise Guidelines, raise the mowing height in hot spells, and check at dusk for armyworm if patches appear quickly.
Apply a pre-emergent for winter grass before it germinates, give a final feed while the lawn is still growing, and watch for brown patch in mild, humid weather.
Growth slows. Mow less often, dig out or spot spray winter weeds while they're small, and plan any renovation for late spring.

- Watch for lawn grubs
- Check your sprinklers before summer
- Core aerate compacted areas
Common weeds by season
| Season | Weeds | Notes |
|---|---|---|
| Autumn | Winter grass, Bindii | Germinate as the weather cools. A pre-emergent works before this happens. |
| Winter | Winter grass, Bindii | Treat or dig out while small. |
| Spring | Bindii, Clover, Onion weed | Bindii forms burrs in spring. |
| Summer | Nutgrass, Clover |
Pests and diseases to watch
Lawn grubs are most active from spring into early summer, and armyworm from about December to March in warm-temperate areas. Brown patch can appear in mild, humid spells in spring and autumn, so water in the morning.
Watering and water rules
