Lawn Installation in Adelaide — Step-by-Step

A new lawn in Adelaide is a 12-month project from order to “really established.” The 6-week mark is when the lawn looks like a lawn; the 12-month mark is when it’s drought-tolerant and self-sufficient.

Here’s the honest install guide.

What you need to decide first

1. Variety

• Sir Walter buffalo: shade-tolerant, soft, stays green
• TifTuf hybrid couch: drought-tolerant, fine texture, dormant in winter
• Eureka kikuyu: fast-growing, full sun, can be invasive
• Nara native turf: emerging native, lower water but slower

2. Instant turf or seed

• Instant turf: $20–$30/sqm laid; established in 6-8 weeks. The default for Adelaide installs.
• Seed: $5–$10/sqm laid; established in 12-16 weeks. Cheaper but tougher to time and protect.

For a typical 60sqm Adelaide lawn, instant turf is the practical choice.

3. Timing

• Best: autumn (March-May)
• Acceptable: spring (September-November)
• Avoid: summer (December-February — 30-50% loss is normal)

Step 1: Site assessment (week 0)

Walk the area. Note:

• Sun hours per day (matters for variety choice)
• Existing soil type (clay, sand, loam — affects prep)
• Drainage paths (where water goes when it rains hard)
• Foot traffic patterns (paths through the lawn)
• Nearby trees (shade + root competition)
• Existing lawn condition (if replacing)

Step 2: Order materials (week 1-2)

For a 60sqm lawn:

• Turf: order 65sqm (10% extra for cuts and waste)
• Topsoil: 60-90mm depth = 4-6 cubic metres
• Lawn starter fertiliser: 2-3kg
• Pre-emergent herbicide (if existing weeds): per label

Most Adelaide turf suppliers cut turf to order — you book a delivery date, they cut the day before.

Step 3: Site preparation (week 2-3)

This step matters more than any other. Skip it and the lawn fails.

A. Remove existing lawn or weeds

Spray with glyphosate 14-21 days before install. Allow weeds to die fully. Rake or mow off dead material.

For old lawn replacement: skim off the top 50mm with a turf cutter (rental, $80-$150/day).

B. Cultivate the soil

• Dig over to 150mm depth with rotary hoe, fork, or hand cultivator
• Break up clods, remove rocks and roots
• For clay-heavy soil: incorporate gypsum (2-3 kg/sqm) and compost (50mm depth)
• For sandy soil: add compost (50mm depth) for moisture retention

C. Level the surface

• Rake to a fine tilth
• Confirm fall away from buildings (1-2 cm per metre)
• Confirm no low spots that pool water

D. Apply lawn starter fertiliser

Broadcast at the rate per label (typically 30-50g/sqm). Light water in.

Step 4: Install (week 3, day of delivery)

Day before

• Confirm delivery time
• Soak the soil deeply (water sits on surface briefly then drains in)
• Have boards ready to walk on (don’t walk on freshly laid turf)

Day of install

• Receive turf (typically delivered as 1m x 60cm pre-cut rolls or 2m strips)
• Lay within 24 hours; same-day install is best
• Lay first row along straightest edge
• Stagger joins like brickwork (no four corners meeting)
• Cut to fit with sharp turf knife around features
• Roll the laid turf with a water-filled roller (rental $40-$80) to ensure root contact with soil

Same evening

• Water deeply — until water sits at the surface briefly, then drains. About 25mm equivalent.

Step 5: Establishment (weeks 4-9)

The most critical phase.

Week 1

• Water daily, morning, ~15mm
• No foot traffic
• No mowing
• No fertilising

Week 2

• Water daily, morning, 15-20mm
• Walk only when essential, on boards
• Apply fertiliser if not done at install

Week 3-4

• Reduce to every 2-3 days, deeper soak
• First mow when blades reach 80mm (Sir Walter) or 60mm (TifTuf)
• Set mower high; remove only top third

Week 5-6

• Mow weekly
• Water every 3-4 days (or as smart controller dictates)
• Lawn should be “knit” — pull on a piece, doesn’t lift

Week 7-8

• Established
• Water every 5-7 days deep soaks
• Normal foot traffic OK
• Apply second fertilising if needed

Step 6: Year-1 maintenance

• Spring: core aerate (rented machine, $80-$150/day); top-dress with sandy loam
• Summer: weekly deep watering (or smart-controlled); spot-spray weeds
• Autumn: fertilise; assess for pest damage; treat if needed
• Winter: mow as required; stop fertilising

By month 12, the lawn should be drought-tolerant and self-maintaining with weekly mowing in growing season.

Cost summary for 60sqm lawn

Soil + amendments	$300–$700
Site prep (DIY tools rental)	$150–$300
Fertiliser	$50–$120
Total DIY	$1,700–$2,920

Total professional	$3,000–$5,900

Common mistakes

• Skipping soil preparation. “Just lay the turf on the existing dirt.” Lawn looks good for 6 months then fails.
• Installing in summer. 35°C+ days kill freshly laid turf even with daily watering.
• Inconsistent watering. Daily for week 1 then forgotten for 5 days = dead lawn.
• First mow too short. Cut by half = stress. Should remove only top third.
• Walking on it before knit. Damages root growth permanently.
