Lawn care in Adelaide
Adelaide has hot, dry summers and mild, wetter winters. Lawns need the most water exactly when the least rain falls, so efficient summer watering is the biggest part of Adelaide lawn care. Warm-season lawns grow from spring to autumn and slow down over winter.

Short answer
Adelaide's summers are hot and dry and most rain falls in winter, so lawns rely on watering through summer. Warm-season grasses such as couch, kikuyu and buffalo grow from spring to autumn. Water deeply and early, use a wetting agent if water won't soak in, mow a little higher in summer, apply a winter grass pre-emergent in autumn, and check SA Water's water-wise measures.
Adelaide’s lawn year is shaped by its rainfall. Most rain falls in the cooler months, when warm-season lawns are growing slowly, and summers are hot and dry. That means a good summer lawn depends on watering well: deeply, early in the day, and evenly.
The biggest Adelaide lawn jobs are:
- Getting summer watering right. Do a catch-cup test before summer, water deeply and less often, and fix uneven sprinklers rather than running every zone longer.
- Dealing with dry patches. If water beads or runs off, the soil may be water-repellent; a wetting agent and coring help water soak in.
- An autumn pre-emergent for winter grass, applied before it germinates as the weather cools and rain returns.
- Scaling back irrigation in winter, when rain usually does the job.

Best grass types for Adelaide
Hard-wearing in full sun and copes well with heat. Goes dormant and brown over winter.
Hard-wearing and fast-growing in summer. Needs regular mowing and edging, and browns off in winter.
Copes with some shade better than couch or kikuyu. Use only herbicides whose label lists buffalo.
Dense and slow-growing, so it needs less mowing; slows down over winter.
The lawn year in Adelaide
Lawns wake up as the weather warms. Feed once growth is strong, deal with bindii before it forms burrs, and check sprinklers and dry patches before summer.
The hardest season. Water deeply and early on the days you water, raise the mowing height, apply a wetting agent if water beads on dry patches, and watch for lawn grubs.
Apply a winter grass pre-emergent before it germinates, give a final feed while the lawn is still growing, and reduce watering as rain returns.
The wet season. Lawns slow down; switch off or scale back irrigation, mow only when needed, and treat winter weeds while they're small.

| Summer | Nutgrass, Clover | Watered lawns can host summer weeds. |
Pests and diseases to watch
Lawn grubs are most active from spring into early summer, when dry patches and grub damage are easy to confuse. Lift a piece of turf to check. Brown patch can appear in mild, humid spells in spring and autumn.
