Last summer, about half the folks in Karrinyup rang us up worried sick about brown patches taking over their front yards. Everyone thought they were watering enough, but their lawns still looked terrible. Here's what we figured out helping them - and it changed everything.
Those brown spots weren't from lack of water. Most Perth lawns need proper fertiliser and wetta soil products applied each season, not just once a year like most people think. When we started treating lawns in Karrinyup every season with the right products, those brown patches disappeared within 5 weeks. Now their lawns stay green even through our brutal Perth summers.
That's what we do at Alpha Omega Mowing. We're a local lawn care service based right here in Karrinyup, and we've been keeping yards looking good across Perth's northern suburbs for years. From Trigg to Padbury, Duncraig to Doubleview, we know what Perth lawns need because we live here too.

Tired of dull, lifeless greenery? Let’s turn your ouPerth's sandy soil is rough on grass. It drains fast, which sounds good until you realize nutrients wash away just as quick. Add in our long hot summers and those crazy winter downpours, and you've got lawns that need way more attention than people expect.
We see it all the time in Gwelup and Carine - people move here from back east and try the same lawn routine that worked there. Doesn't work. Perth lawns need different care, different timing, and honestly, different products.tdoor space into a masterpiece with expert care and maintenance. Whether it’s a weekly touch-up or a monthly refresh, we ensure your garden stays lush, vibrant, and full of life!

We've been fixing struggling lawns and keeping healthy ones green across Perth's northern suburbs for years.
We've fixed hundreds of struggling lawns across Perth's northern suburbs. Brown spots in Karrinyup, patchy grass in Duncraig, weed problems in Gwelup - same issues you're dealing with. These photos show real yards we've transformed with proper seasonal care and the right products. No fancy tricks, just Perth lawns that got the attention they needed and came back strong.










Here's something most mowing services won't tell you - cutting your lawn wrong damages it more than not mowing at all.
We see butchered lawns every week in North Beach and Waterman's Bay. Other companies scalp the grass too short (makes it easier for them to go longer between cuts), which stresses the roots and lets weeds take over. Or they mow when the grass is wet, which tears it instead of cutting clean.
Our lawn mowing service does it right. We adjust blade height based on your grass type and the season. We never cut more than one-third of the blade length at once. And we sharpen our blades constantly - dull blades rip grass and leave it vulnerable to disease.
Regular mowing also stops weeds before they seed. That's huge in suburbs like Hillarys and Sorrento where one yard with seed heads can spread weeds to the whole street. Learn more about our Lawn care Services here
Your reticulation system should make life easier. But we get calls weekly from frustrated homeowners in Innaloo and Stirling whose systems waste water, miss patches, or won't turn on at all.
As an experienced lawn sprinkler system contractor, we fix what's broken and design systems that actually work with Perth's water restrictions. We install smart controllers that adjust for weather, replace broken sprinkler heads that spray sideways, and redesign zones so your lawn gets even coverage.
Most importantly, we set up systems that match your lawn's real needs - not just spray water everywhere and hope for the best. Sandy soil in areas like Doubleview needs different watering than the heavier soils you find in pockets of Duncraig.

Walk into any hardware store and you'll find fifty different fertiliser bags. They all claim to be perfect for Perth lawns. Most aren't.
We've tested everything over the years - the cheap stuff, the expensive imports, the organic options. What we found is Perth lawns do best with slow-release fertilisers that match our soil conditions. Quick-release fertilisers might green up your lawn fast, but in sandy soil they wash straight through before the grass can use them.
As a local fertiliser supplier, we stock what actually works here. And our fertiliser supply and spread service means you don't have to guess about application rates or timing. We apply the right amount at the right time - usually four times a year for healthy lawns.
That seasonal approach is what fixed all those brown spots in Karrinyup last summer. One application in spring isn't enough when nutrients drain away so fast.
Sometimes you need more than just mowing. Gardens get overgrown, hedges grow wild, and suddenly your whole yard looks messy even though the lawn's fine.
Our gardener services cover the whole picture. We prune shrubs so they stay healthy and look good. We weed garden beds properly - getting the roots, not just chopping off the tops. We mulch to keep moisture in and weeds down.
In suburbs like Trigg and Marmion where salt spray affects plants, we know which species struggle and which ones thrive. That local knowledge makes a huge difference when you're trying to keep gardens looking good year-round.

Most lawn services use rotary mowers because they're faster and easier. We don't. We use cylinder mowers for a reason - they give a cleaner, healthier cut that Perth grass actually responds to.
Cylinder mowers cut like scissors, slicing the grass blade cleanly instead of tearing it. That matters more than you'd think. Clean cuts heal faster, look better, and make your lawn more resistant to disease and heat stress. In Perth's harsh summers, that's the difference between grass that struggles and grass that thrives.
We see the results every week in Karrinyup and Duncraig. Lawns we've been mowing with cylinder mowers for a few months look noticeably thicker and healthier than neighboring properties using standard rotary cuts. The grass grows back stronger, the color's better, and weeds have a harder time getting established.
Our lawn mowing service isn't just about keeping the grass short. We adjust cutting height based on the season and your grass type. We never scalp the lawn - that stresses the roots and opens the door for weeds. And we mow regularly enough that we're never taking off more than a third of the blade length at once.
Regular cylinder mowing also stops weeds before they become problems. In suburbs like Gwelup and Padbury where seed heads spread fast, consistent mowing keeps weeds from going to seed and taking over the whole street.

There's regular mowing, and then there's mowing with proper grass edging. The difference is obvious.
Crisp edges along paths, driveways, and garden beds make even a simple lawn look professionally maintained. But it takes the right equipment and technique - whipper snippers make a mess, and spades take forever.
We edge every property we mow, using proper edging tools that create clean lines without tearing up the grass or damaging roots. It's that finishing touch that makes neighbors in Padbury and Carine ask "who does your lawn?"

Not every property is just lawn. Lots of homes in suburbs like Waterman's Bay have native sections, vacant blocks next door, or back areas that got away from previous owners.
Our brush cutting service handles the heavy stuff - thick weeds, overgrown native scrub, areas that haven't been touched in years. We've got the equipment to clear it properly without damaging good plants or leaving a mess behind.
This is especially important before fire season. Overgrown brush is a real risk, and the rangers don't mess around with compliance.

After mowing, there's always clippings, leaves, and debris scattered around. Some services just leave it. We don't.
Our air blower brooming service clears all hard surfaces - driveways, paths, patios, even out to the street. It's quick, thorough, and makes your whole property look finished, not just the lawn.
People notice this in areas like North Beach where sea breeze constantly blows debris around. A quick blow-over makes everything look fresh and cared for.

Thatch builds up in lawns over time - that layer of dead grass and roots between the green grass and soil. A bit is fine. Too much chokes your lawn and stops water and nutrients getting to the roots.
Vertimowing cuts through that thatch and pulls it out. It looks brutal when we're doing it - the lawn looks torn up and rough. But within a couple weeks, the grass comes back thicker and healthier than it's been in years.
We do a lot of vertimowing in spring throughout Gwelup, Duncraig, and Doubleview. That's when Perth lawns respond best, and you've got warm weather ahead for recovery.

Life gets busy. Sometimes yards get neglected for months. We get it - no judgment.
Our yard clean up service tackles properties that need serious work. Overgrown grass, weeds everywhere, piles of leaves, dead plants - we clear it all and get your yard back to manageable.
We've done clean ups in Karrinyup where the grass was knee-high and full of bindiis. Took us a full day, but when we finished it looked like a different property. Then we put them on a regular schedule so it never gets that bad again.

If you've got a larger block in suburbs like Sorrento or Hillarys, you know about fire break requirements. Council takes this seriously, and the fines for non-compliance aren't cheap.
Our fire break service creates breaks that meet all local regulations. We know the required widths, what needs clearing, and when it needs doing. We handle the whole job - clearing vegetation, disposing of material properly, and making sure you're compliant before inspection season.

Perth's water restrictions mean your reticulation system needs to work perfectly. You can't waste your watering days on broken systems or inefficient sprinklers.
We repair broken pipes, replace damaged sprinkler heads, fix controllers that won't program, and track down leaks that are wasting water. We also do regular maintenance to prevent problems - checking for pressure issues, adjusting spray patterns, and making sure everything's ready before summer hits.
In areas like Innaloo and Stirling where bore water is common, we make sure your system handles the different water quality without clogging or corroding.

Pulling weeds is fine for small areas. But when you've got broadleaf weeds or onion grass taking over your whole lawn, you need proper weed control spray service.
We use selective herbicides that kill weeds without harming your grass. Timing matters heaps - spray too early or too late in the season and it doesn't work properly. Spray in the wrong weather and you're wasting product.
We see a lot of weed problems in Carine and Padbury where lawns have gotten thin over time. Weeds move into weak spots. So we combine weed spraying with proper fertilising to help the grass thicken up and crowd out new weeds naturally.
We're not a franchise with crews driving in from all over Perth. We're based in Karrinyup and we work the northern suburbs every day. That matters more than you'd think.
We know which streets flood every winter and need different drainage. We recognise the soil differences between suburbs. We understand seasonal timing - when to fertilise, when to spray, when lawns need extra water even during restrictions.
When someone in Trigg calls about their struggling lawn, we already know their street probably has that heavy alkaline layer of limestone sand. Grass loves more acid soils so there are things we do differently here as to if we were assessing a job in Duncraig. When a Marmion customer asks about salt-tolerant plants(one of the closest suburbs to the (Indian ocean), we've got years of experience with what works there.
Perth lawns can look great year-round, but it takes the right approach for each season.
Spring needs vertimowing and heavy fertilising as grass starts growing fast. Summer requires smart watering schedules and wetta soil products to handle the heat. Autumn is perfect for weed control before winter weeds germinate. Winter needs less mowing but careful disease management with all the rain.
Most homeowners just mow whenever it looks long and hope for the best. That's why half the lawns in any suburb look average while the other half look great - it's all about timing and seasonal care.
