Melbourne's climate is genuinely challenging for gardens. We get hot, dry summers that stress lawns and plants, cold wet winters with minimal growth, and a spring and autumn that can swing 20 degrees in a week. The good news is that with the right tasks at the right time of year, you can keep your garden looking great without it becoming a full-time job.
Here's a practical, season-by-season guide for northern Melbourne properties — based on what we see working in Epping, Thomastown, Mill Park, South Morang and the surrounding suburbs every week.
Spring (September – November): The Growth Rush
Spring is the busiest season in the garden — and the most rewarding. After winter's dormancy, everything starts growing fast and the temperature is still manageable for working outside.
Lawns
Give your lawn its first proper mow of the season, but don't cut it too short — leave it at around 40–50mm to help it establish before summer heat arrives. This is also a good time to apply a slow-release lawn fertiliser to kick off the growing season.
Garden beds
Clear out winter weeds before they go to seed — once they've seeded, you'll be dealing with them for years. Add a layer of mulch (50–75mm) over garden beds to suppress new weeds and retain moisture heading into summer.
Pruning
Spring is the time to prune plants that flower on new growth — roses, hydrangeas and many Australian natives. Wait until the threat of frost has fully passed (usually mid-October in northern Melbourne) before hard pruning tender plants.
Gutter check
After the leaf fall of autumn and winter, spring is a great time for a gutter clean. Clear out what's accumulated over winter before summer storm season starts.
Summer (December – February): Survival Mode
Melbourne summers are tough on gardens. Hot, dry spells can kill lawns and stress established plants very quickly. The focus in summer is keeping things alive rather than making them grow.
Watering
Water deeply and infrequently rather than shallow and often. Deep watering encourages roots to go down, which makes plants more drought-tolerant. Early morning is the best time — less evaporation, no fungal issues. Avoid watering in the middle of the day.
Lawns
Raise your mowing height in summer to 50–60mm. Taller grass shades the soil, reduces moisture loss and handles heat stress better. If the lawn goes yellow or dormant, don't panic — most turf types recover with the autumn rains.
Mulch top-up
Check your mulch depth in December. After a few months it breaks down and compacts. A top-up heading into the hottest months makes a big difference to soil moisture retention.
Pruning
Avoid hard pruning in summer — cutting back stimulates new growth which can get burnt by the heat. Light tidying is fine; save the serious pruning for autumn or late winter.
Autumn (March – May): Prepare for Winter
Autumn is arguably the most important season for garden maintenance in Melbourne. The weather is mild and pleasant for working outside, and the jobs you do now set your garden up for the whole winter.
Leaf clean-up
Deciduous trees drop their leaves through April and May. On top of looking untidy, rotting leaf litter can smother lawn and garden beds, create breeding grounds for pests and block gutters. Stay on top of it with regular raking or a blower.
Gutter cleaning
May or June is the ideal time for a gutter clean in Melbourne — most leaves have fallen but the heavy winter rain hasn't started yet. Blocked gutters in winter lead to overflow, water damage and potentially serious structural issues.
Lawn feeding
Apply an autumn lawn fertiliser in March or April. Choose a formulation higher in potassium to help the grass toughen up for winter. This is also the time to oversow any bare patches.
Planting
Autumn is the best time to plant most trees, shrubs and perennials in Melbourne. The soil is still warm from summer, the rain is on its way, and plants can establish roots before summer heat arrives. A plant put in the ground in April has a much better survival rate than one planted in January.
Winter (June – August): Low Maintenance, Smart Prep
Growth slows dramatically in winter, which means maintenance is at its lowest. But there are still a few important tasks that set you up for a great spring.
Pruning
Late winter (August) is the best time to prune most deciduous trees and shrubs — they're dormant, so you can see the structure clearly and cuts heal quickly when growth resumes. This includes fruit trees, roses and ornamental shrubs.
Weed control
Winter weeds (bindii, winter grass, clover) are actively growing when your lawn isn't. Spot-treat or hand-pull while they're small, before they go to seed and the problem gets much worse.
Check drainage
Walk around your property after heavy rain. Pooling water, soggy patches and overflow points indicate drainage issues that are worth addressing. Water that pools near the house can cause foundation problems over time.
Deck and fence check
Winter is a good time to inspect your deck and fence for moisture damage. Probe timber with a screwdriver — if it sinks in easily, there's rot. Catching it in winter means you can plan repairs before the spring entertaining season.
The Bottom Line
Melbourne gardens reward consistent attention more than big occasional efforts. A few hours of targeted work each season — or a regular monthly maintenance visit — is far more effective than a big annual clean-up when things have gotten out of hand.
If you'd rather spend your weekends enjoying your garden than maintaining it, we're happy to help. We provide regular garden maintenance across Epping, Thomastown, Mill Park, South Morang, Mernda and surrounding northern Melbourne suburbs.
