Laying turf transforms a bare or tired backyard into a usable lawn quickly. But in Perth, where the soil is sandy and summers are harsh, the job done without proper preparation rarely lasts. The preparation is where most lawn installations succeed or fail.
This is a complete turf laying guide for Perth. It covers soil preparation, the laying process, watering exemptions, and what lawn care to apply in the first few weeks. If you would prefer a professional to handle the new lawn installation, see our Turf Installation Perth page for details on what we supply and install.
Before You Start: What to Think Through First
A few decisions made before any soil is turned will save significant time and cost later.
Choose your turf variety before anything else
Different lawn varieties suit different conditions. Sun exposure, foot traffic, and water availability all shape which variety performs best in a given yard. The main lawn varieties installed across Perth are Sir Walter Buffalo, Palmetto Buffalo, Kikuyu, Wintergreen Couch, and TifTuf.
To choose the right variety, consider how much shade the area gets, how much use it receives, and whether a softer feel or a tougher, faster-growing grass suits your needs better. A separate article in this series compares each variety in detail.
Measure the area accurately
Calculate the total square metres by multiplying length by width. For irregular shapes, break the area into sections, calculate each one, then total them. Add around 5 to 10 percent to allow for cuts, trimming around edges, and any waste. Ordering short means delays when the turf has already been cut and is waiting to go down.
Check your irrigation system before laying
New turf needs consistent watering to establish, particularly in its first few weeks. An irrigation system with unresolved faults or heads that have not run in a while should be checked before the turf goes down. Fixing or adjusting heads after turf installation is disruptive and risks damaging a newly laid lawn. See our Irrigation Repairs Perth page if your system needs attention before installation.
Best time of year to lay turf in Perth
Turf can be laid year-round in Perth’s warm, dry climate. The best time to lay turf in Perth is spring, September to November, or early autumn, March to April. During these windows the soil temperature supports fast root establishment without the stress of peak summer heat.
Summer installation is possible but requires more intensive watering and a Water Corporation watering exemption for the establishment period. Winter installation works well in Perth’s mild climate, uses less water, and allows the turf to establish ready for spring growth.

Step 1: Clear and Prepare the Site
Good base preparation is the single most important factor in a successful lawn installation in Perth. Most lawn failures in WA trace back to poor soil conditions under the roots, not the turf itself.
Remove existing lawn, weeds, and debris
Strip out any existing grass, weeds, rocks, sticks, and building debris from the site. Never lay new turf directly over old lawn. The layer of dead material underneath prevents roots from establishing and causes drainage problems.
For large areas or established lawns, a non-selective herbicide applied one to two weeks before work begins kills off existing vegetation thoroughly. Follow up with a second application if regrowth appears. Allow sufficient time for the herbicide to break down before laying new turf.
Prepare the soil: the critical step for Perth properties
Perth soils are predominantly sandy. Sandy soil drains too fast, holds little moisture, and lacks the nutrients turf needs to establish. Laying turf on sandy soil without amendment is one of the most common reasons new lawns fail in Perth.
Turf needs around 100mm of workable topsoil to root into. The best soil base for Perth lawns is a sandy loam, roughly an 80/20 mix of sand and organic matter. Sandy loam holds moisture without waterlogging, retains nutrients, and gives roots room to grow. Adding a wetting agent to the soil before laying is also worthwhile on Perth properties, as it helps water penetrate and stay in the sandy soil profile.
The Turf Growers Association of WA recommends blending red or yellow sands with quality organic matter as the base for new lawns on the Swan Coastal Plain. Spearwood or Gingin Red sands are commonly used. A premium lawn blend or soil conditioner from a local supplier works well for most Perth residential soil preparation for turf installation.
Check and adjust soil pH
pH levels affect how easily grass absorbs nutrients from the soil. The ideal pH range for turf is 6 to 7.5. Outside this range, grass struggles to take in nutrients even when they are present. A basic pH test kit from a garden supplier gives a reading in minutes.
WA soils are often slightly acidic. Applying dolomite corrects acidity and adds magnesium, a mineral that is commonly deficient in Perth soils. For soils with a pH above 7.5, plain elemental sulphur brings it down. Your local garden supplier can advise on application rates.
Level and settle the surface
Rake the prepared soil to an even, smooth surface. Keep the finished soil level approximately 30 to 50mm below the height of paths, driveways, and edging. This allows for the thickness of the turf itself, so the lawn sits flush with surrounding surfaces once laid.
Once levelled, lightly roll or compact the surface to firm it up. This reveals any low spots that need filling before turf goes down. A firm, even base prevents the turf from settling unevenly after installation.
Apply a starter fertiliser
Spread a quality starter fertiliser evenly across the prepared surface before laying. Starter fertilisers give new roots immediate access to nutrients as they begin to grow into the soil. A slow-release product is preferable to a fast-release option, which can burn newly established roots. Some installers also apply a light top dress of quality soil mix at this stage to improve the surface finish.
Step 2: Laying the Turf
With the base prepared, get the instant turf laid as quickly as possible after delivery. Turf is a living product and its condition declines fast once cut, particularly in warm weather. In hot conditions, keep unrolled turf in shade and apply a light mist while working through each section.
Start along the longest straight edge
Begin at the longest straight boundary, such as a fence line, driveway, or path. Unroll the first run of turf carefully and press it firmly against the edge. Progress back toward the access point so that completed sections are not walked over as work continues.
Lay in a staggered brickwork pattern
Offset each row so that the joins do not line up in straight runs. A staggered brickwork pattern reduces visible seam lines and strengthens the overall lawn structure. Butt each piece firmly against its neighbour without stretching or overlapping. Gaps cause dry edges that knit slowly.
Trim turf around edges, trees, garden beds, and curved areas using a sharp knife or spade. Keep offcuts nearby until the whole area is covered, as irregular pieces often come in useful for awkward gaps.
Laying turf on slopes
On sloped ground, lay turf across the slope rather than up and down it. This reduces the risk of pieces sliding before they root. On steep slopes, turf pegs or stakes hold pieces in position until roots establish.
Roll the turf after laying
Once all turf is down, roll or walk over the entire area to improve soil-to-turf contact and remove air pockets. Air pockets prevent roots from reaching the soil and cause dry patches and dead spots. This step is easy to skip but makes a real difference to how well the turf establishes.
Step 3: Water Immediately After Laying
Water the turf thoroughly as soon as each section is laid. Waiting until the whole roll on lawn is finished before watering risks sections drying out, particularly in warm conditions. The first watering needs to be deep enough to wet the turf and soak the soil beneath.
New turf in Perth requires a watering exemption from the Water Corporation. Normal roster rules allow watering twice a week, which is not enough to establish a new lawn. Apply for the exemption on installation day at watercorporation.com.au. Spring and summer installations receive up to 42 days of daily watering. Autumn and winter installations receive up to 35 days.
After Installation: The First Few Weeks
The establishment period is when most new lawns either take hold or struggle. The turf is alive but the root system has not yet anchored into the soil. Consistent moisture and minimal disturbance give it the best chance to knit in properly.
Watering during establishment
Water the new lawn daily during the exemption period. In the first week, warm conditions may call for two or three sessions a day to keep the root system moist. Reduce frequency gradually over the following weeks as roots grow deeper. Good lawn care in this period is the difference between a lawn that takes hold and one that struggles.
The goal is to keep the soil moist beneath the turf, not just the surface. Lift a corner of a turf piece after watering to check that moisture has penetrated through to the soil below.
Limit traffic on the lawn
Keep foot traffic, pets, and children off the new lawn for the first two to three weeks. Concentrated traffic on unrooted turf causes depressions, separates joins, and can kill patches before they establish. Once turf resists a gentle tug when you lift a corner, the roots have begun to hold.
When to mow for the first time
The first mow should wait until the turf has clearly taken hold and resists a gentle tug at the corner. In summer this is usually within 10 to 14 days of laying. In cooler conditions it may take 14 to 21 days.
Use a high cutting height for the first cut. Cutting too low before the root system is well established stresses the grass at its most vulnerable stage.
Apply fertiliser at six weeks
Apply a lawn fertiliser around six weeks after installation. At this stage the root system has established well enough to absorb nutrients effectively. Earlier application risks burning shallow roots before they are strong enough to handle it.
Common Turf Laying Mistakes in Perth
These are the errors that most often lead to patchy, struggling, or failed lawns after installation in Perth.
- Laying over an existing lawn. Putting new turf directly over an existing lawn or weeds is one of the most reliable ways to get a failed result. The layer of dead material underneath prevents the root system from establishing and causes drainage problems.
- Skipping soil preparation on sandy ground. Laying turf on sandy soil without adding conditioner or topsoil is the most common cause of lawn failure in Perth. The turf looks fine for a few weeks, then declines as the root system finds nothing to hold onto.
- Not applying for a watering exemption. Watering new turf to the normal roster schedule of twice a week is not enough to establish it in Perth’s conditions. Apply for the exemption on installation day.
- Leaving gaps between turf pieces. Gaps dry out fast in Perth’s heat and do not fill in reliably. Butt each piece tightly against the next without stretching.
- Delaying the first watering. Turf dries out fast once cut. Water each section within 30 minutes of laying in warm conditions.
- Leaving out the rolling step. Air pockets between the turf and soil lead to dry patches that do not recover. Rolling takes minutes and makes a real difference.
- Cutting too early or too short. The first mow before the root system has anchored, or cutting at too low a height, stresses the grass at the worst possible time.
When to Use a Professional Installer
Laying turf is a manageable DIY project for smaller areas with straightforward ground conditions. Larger areas, sloped sites, poor soil, or properties with drainage issues are better handled by a professional turf installer with the right equipment and experience.
A professional handles soil assessment, turf underlay, levelling, and the lay itself. On Perth’s sandy soils, thorough soil preparation for turf is where the real value lies. Getting it right from the start avoids costly repairs or full relaying later.
