When to Mow New Turf?

A beautiful new lawn is a source of pride and joy for any homeowner. But to keep it looking its best, knowing when and how to mow new turf is crucial. Mowing at the right time and with the right technique sets the foundation for a healthy, resilient lawn that thrives for years to come.

Let’s dive in to ensure your new lawn gets the perfect start!

When Should You Mow New Turf for the First Time?

The Critical Waiting Period

After laying new turf, patience is your best friend. Mowing too soon can damage tender roots and set back your lawn’s progress. We at Roberts Turf recommend waiting 2–4 weeks after installation before the first mow, but the exact timing depends on several factors:

• Weather: Turf establishes faster in warm weather (10–14 days) and slower in cooler conditions (14–28 days).
• Grass Type: Some turf varieties root faster than others.
• Soil Moisture: Consistent watering helps roots establish but avoid overwatering.

Signs Your New Turf Is Ready for Mowing

Before you reach for the mower, check these key indicators:

The Tug Test

Gently tug at a corner of the turf. If it lifts easily, the roots haven’t established yet—wait a few more days and test again. If there’s firm resistance and you see white roots anchoring into the soil, your turf is ready for its first cut.

Visual and Soil Checks

• Knitting Together: The turf should appear woven together, not as separate pieces.
• Soil Firmness: The ground should be firm, not soft or squelchy underfoot.
• Grass Height: Most new lawns are ready for mowing when the grass reaches about 6–8 cm (2.5–3 inches) tall.

Walking on New Turf: When Is It Safe?

Why You Should Avoid Walking on New Turf Initially

Walking on newly laid turf too soon can cause serious damage. In the first two to three weeks, the turf’s roots are still establishing themselves in the soil beneath. Foot traffic during this critical period can:

• Compact the soil, making it harder for roots to penetrate deeply
• Disturb the turf slabs, causing uneven patches, bumps, or gaps between turf pieces
• Lead to bare spots or permanent damage, reducing the lawn’s durability and health

Soil compaction from walking restricts air and water flow to roots, increasing the risk of weak growth and disease.

For these reasons, patience is essential to allow your new lawn to develop a strong root system.

How Long Should You Wait Before Walking on New Turf?

• Minimum waiting time: At least 2–3 weeks before light foot traffic is allowed
• Best practice: Wait up to 6 weeks or until the turf is firmly rooted and the soil feels solid underfoot
• Grass type considerations: Some slow-establishing varieties like Zoysia may require longer periods without traffic to fully root

Tips to Protect Your New Turf from Foot Traffic

• Limit access: Keep pets, children, and heavy foot traffic off the lawn during the establishment phase
• Temporary pathways: If you need to cross the lawn, lay down boards or planks to distribute weight and reduce pressure on the turf
• Avoid walking on wet turf: Wet soil compacts more easily, so wait until the lawn and soil are dry before stepping on it

What to Do If You Accidentally Walk on New Turf

If you accidentally walk on new turf before it’s ready:

• Inspect for any displaced or damaged turf pieces and gently press them back into place
• Avoid further traffic and increase watering to help the turf recover
• Monitor for signs of stress such as browning or thinning and adjust care accordingly
  

How to Mow New Turf: Step-by-Step

Preparing for the First Mow

• Mower Blades: Always use sharp blades to avoid tearing the grass.
• Mower Setting: Set the mower to its highest setting for the first cut.
• Dry Grass: Mow only when the grass is dry to prevent clumping and damage.
• Clippings: Collect and remove clippings to reduce stress on the new turf.

The One-Third Rule

Never remove more than one-third of the grass blade in a single mow. Cutting too much at once stresses the plant, weakens the root system, and can lead to browning or disease.

After the First Mow

• Gradually Lower Height: For subsequent mows, you can gradually reduce the mowing height, but always follow the one-third rule.
• Frequency: Mow weekly in warm conditions and less often in winter.
• Direction: Change mowing direction each time to encourage upright growth and prevent ruts.

Common Mistakes to Avoid When Mowing New Turf

Mowing Too Early

Cutting before the roots are established can pull up the turf and damage your investment. Always perform the tug test and wait if there’s any doubt.

Cutting Too Short (Scalping)

Mowing too low exposes roots, increases water loss, and encourages weeds. Stick to the recommended height for your grass type and never scalp the lawn.

Mowing Wet Grass

Wet grass tears more easily and clumps, leading to uneven cuts and potential disease. Wait until your lawn is dry before mowing.

Ongoing Mowing and Maintenance for New Lawns

Establishing a Mowing Schedule

• Warm Months: Mow weekly or as needed when growth is vigorous.
• Cool Months: Mow less frequently—every 3–6 weeks, depending on growth.
• Monitor Growth: Adjust your schedule based on rainfall, temperature, and grass health.

Additional Lawn Care Tips

• Watering: Water deeply but less frequently as roots establish.
• Fertilising: Apply a balanced fertiliser about six weeks after laying turf, then seasonally as recommended for your grass variety.
• Traffic: Avoid heavy use until the lawn is well established (usually 6–8 weeks).

Grass-Specific Mowing Advice

Every turf variety has unique needs. Here’s how to care for some of Australia’s most popular lawns:

Wintergreen Couch

• Mowing Frequency: Every 7–14 days in summer, fortnightly in winter.
• Mowing Height: 15–30 mm (1.5–3 cm). Keep it on the higher side in shade or cooler months.
• Sunlight: Needs at least 5 hours of direct sunlight daily.
• Technique: Use sharp blades, never remove more than one-third of the leaf, and avoid mowing when wet.
• Other Tips: Fertilise six weeks after installation, then twice in summer and once each in spring and late autumn. Water 2–3 times a week in summer, less in cooler seasons.

Sapphire Buffalo

• Mowing Frequency: Every 5–10 days in summer, every 3–6 weeks in winter.
• Mowing Height: 2–5 cm in sun, 5–7 cm in shade.
• Features: Less mowing needed than Couch or Kikuyu. Soft leaf, excellent shade tolerance, and retains blue-green colour in winter.
• Technique: Use sharp blades, avoid thatch buildup, and mow regularly to prevent seed production.

Nara Native Zoysia

• Mowing Frequency: Once a week or less, depending on fertiliser and growth.
• Mowing Height: 20–45 mm (2–4.5 cm). Longer leaf improves shade and frost tolerance.
• Features: Needs 20% less mowing than Buffalo, 35% less than Couch. Slow growth and low maintenance.
• Technique: Rotary or cylinder mower, avoid mowing too short, and use sharp blades.

Augusta Zoysia

• Mowing Frequency: Every 2 weeks in warm months, every 3–8 weeks in cold months.
• Mowing Height: 2–5 cm in sun, 5–7 cm in shade.
• Features: High shade tolerance, low maintenance, and slow growth.
• Technique: Cut no more than one-third of the leaf, use sharp blades, and remove clippings. Fertilise in spring and autumn.

Frequently Asked Questions

Can I walk on my new turf before mowing?

Light foot traffic is okay after 3–4 weeks, but avoid heavy use until the lawn is well established (6–8 weeks).

Should I mow new turf if it’s raining or the ground is soft?

No. Wait until the grass and soil are dry and firm to avoid ruts, compaction, and uneven cuts.

What if my grass grows too tall before the first mow?

If your grass exceeds the recommended height, mow in stages—never remove more than one-third of the blade at a time. Gradually bring it down to the ideal height over several mows.

How do I prevent weeds in new turf?

Regular mowing, proper fertilising, and watering schedules help crowd out weeds. Spot-treat weeds if necessary, but avoid harsh chemicals on very young lawns.
