South-east Queensland doesn't have four distinct seasons the way southern Australia does. The differences are subtler — wet and dry, hot and mild — but they matter enormously for how you maintain a garden. What works in July fails in January. Here's what Brisbane gardens typically need, season by season.
Summer (December – February): manage the growth surge
Brisbane summers are hot and humid, often with significant rainfall. Gardens grow fast — sometimes aggressively fast. Lawns can need mowing every 7–10 days at peak growth. Hedges like Lilly Pilly and Murraya will push hard and lose their shape quickly. Weeds compete for resources and can establish in days.
Increase mowing frequency. Fortnightly is a minimum; weekly or 10-day intervals may be needed for fast-growing couch and kikuyu.
Trim hedges every 6–10 weeks if you want them to hold a formal shape through the growing season.
Weed garden beds before weeds set seed — once seed is dispersed, the problem multiplies fast in summer conditions.
Check for lawn grubs — armyworm and webworm are active in summer and can devastate a lawn in a few days.
Mulch garden beds to a 75mm depth to retain soil moisture between rain events and suppress weeds.
Autumn (March – May): consolidate and prepare
Autumn is the most forgiving season for Brisbane gardens. Growth slows, temperatures drop, and conditions become more manageable. It's a good time for planting, fertilising lawns, and addressing anything that got ahead of you through summer.
Fertilise lawns in early autumn to support root development heading into winter. Slow-release lawn food is appropriate now.
Renovate bare patches — autumn's mild conditions give new turf time to establish before winter.
Prune summer-flowering shrubs after their display has finished.
Clean gutters as deciduous trees begin dropping leaves — autumn is the main leaf-fall period for many Brisbane garden trees.
Scale back mowing frequency as growth slows — monthly visits may be sufficient by late autumn.
Winter (June – August): low maintenance, targeted care
Brisbane winters are mild and dry. Most lawns slow significantly or go into a semi-dormant state. This is the quietest maintenance period of the year, but there are a few things worth attending to.
Don't over-mow dormant lawns — buffalo grass in particular can be stressed by cutting too short in winter.
Prune roses and deciduous fruit trees while they're dormant in July.
Address weeds while they're small — broadleaf weeds that establish in winter can be hard to eliminate once spring growth kicks in.
Winter is a good time for hard garden work — bed renovation, soil improvement, major pruning — before the heat returns.
Spring (September – November): prepare for the surge
Spring in Brisbane is brief and intense. Gardens wake up quickly, often before homeowners are ready. The couple of weeks either side of Labour Day mark the start of aggressive growth for most Brisbane lawn types. Act early in spring, not reactively in summer.
Book your regular mowing crew in advance — spring demand is highest and schedules fill fast.
First spring fertilise in late September to give lawns a strong start before the heat arrives.
Refresh mulch in garden beds before the summer heat and rain arrive.
Complete any major pruning before plants hit their growth peak — it's much harder to manage a hedge that's doubled in size.
Check irrigation systems if you have them — the dry stretch before the wet season is when they matter most.
The simplest approach: set a schedule and adjust
The biggest mistake Brisbane homeowners make is treating garden maintenance as reactive rather than preventive. A lawn mowed fortnightly through summer never becomes an emergency job. Hedges trimmed every two months never become a major pruning project. The work is lighter, the results are better, and nothing gets ahead of you.
If your schedule doesn't allow for it, a reliable maintenance team like Oxley GPM can handle it on a recurring basis — adapting frequency to the season, keeping the property looking consistently tidy.
