📏 How Tall Should Grass Be Before the First Cut?

The most important rule is height, not age.

• Grass should reach 7–8cm (around 3 inches) before the first mow
• Roots need time to establish before cutting
• Cutting too early can pull seedlings out of the soil

If the grass looks thick and stands upright, it’s usually ready.

🌱 First Mow After Seeding a Lawn

For newly seeded lawns:

• Wait 3–4 weeks, depending on weather
• Ensure grass is well-rooted and evenly growing
• Avoid mowing if soil is still soft or wet

Before mowing, gently tug the grass — if it resists, roots have anchored.

🌿 First Mow After Laying Turf

For newly laid turf:

• Wait 2–3 weeks before mowing
• Turf should feel firmly rooted
• Lift a corner — if it resists, it’s ready

Never mow turf that can still be lifted easily.

✂️ How to Mow the Lawn for the First Time

The first cut should be gentle.

• Set mower blades high
• Remove no more than one-third of grass height
• Use sharp blades only
• Mow when grass is dry

Avoid turning sharply or stopping suddenly on young lawns.

🕐 Best Time of Day for the First Mow

• Late morning or early afternoon is ideal
• Grass should be dry
• Avoid mowing during heatwaves or frost

Dry conditions reduce disease and prevent soil damage.

🚫 What Not to Do on the First Cut

🚫 Don’t cut grass short
🚫 Don’t mow wet ground
🚫 Don’t use blunt mower blades
🚫 Don’t mow during drought or frost
🚫 Don’t rush — patience matters

The first mow sets the tone for long-term lawn health.

🌱 Aftercare Following the First Mow

• Water lightly if conditions are dry
• Avoid heavy foot traffic
• Continue mowing regularly but gently
• Gradually lower cutting height over several weeks

Strong roots develop through consistent, careful mowing.

🌟 Final Thoughts

The key to when to mow the lawn for the first time is waiting until grass is tall, rooted, and strong enough to cope with cutting. Start high, go slow, and avoid stress — your lawn will thicken naturally and stay healthier long term.
