Fortnightly vs Weekly Mowing: Which Costs Less Long-Term?

Fortnightly vs Weekly Mowing: Which Costs Less Long-Term?

If you’re paying someone to mow your lawn, one of the biggest questions is simple: should you have your lawn mowed weekly or fortnightly?

At first glance, fortnightly mowing looks like the obvious cheaper option because you’re paying for fewer visits. But there’s more to the calculation than simply counting how many times the mower arrives.

The right mowing schedule can save you money, keep your lawn healthier and prevent expensive overgrown lawn clean-ups.

For most Bay of Plenty properties, fortnightly mowing offers excellent value for much of the year, while weekly mowing becomes more worthwhile during periods of fast growth, particularly through summer.

Weekly vs Fortnightly Mowing: The Basic Difference

The simplest way to look at the two options is:

Mowing ScheduleBest ForTypical Lawn Mowing Price
WeeklyFast-growing lawns & premium finishFrom $45 per visit
FortnightlyMost residential lawnsFrom $50 per visit
MonthlySlow-growing or shaded lawnsFrom $60 per visit
One-offOvergrown or occasional mowingFrom $75 per visit

These are starting prices. Your actual price depends on factors such as lawn size, access, slope, edging requirements and how long the grass has become.

Is Fortnightly Mowing Cheaper?

Yes, if your lawn can comfortably handle two weeks between cuts.

Because you are booking fewer visits, your total annual mowing cost is normally lower.

For example, imagine a lawn that costs around $50 per fortnightly visit.

Over a 12-month period, you could have approximately 26 scheduled visits:

26 × $50 = $1,300 per year

A weekly schedule at $45 per visit would be approximately:

52 × $45 = $2,340 per year

So even though the weekly price per visit is lower, you are paying for twice as many visits.

That’s why fortnightly mowing generally costs less overall.

However, there is an important catch.

The Cheapest Schedule Isn’t Always the Cheapest Lawn

Skipping mowing visits can sometimes create a false saving.

If you leave a lawn for too long, the grass can become significantly longer. When that happens, the next mowing job takes longer, produces more clippings and may require additional work.

An overgrown lawn can take two or three times longer to mow than a regularly maintained lawn.

So instead of thinking:

“How few times can I mow my lawn?”

A better question is:

“What’s the least frequent schedule that keeps my lawn under control?”

For many Bay of Plenty lawns, that answer is fortnightly for much of the year.

When Weekly Mowing Makes More Sense

Weekly mowing is usually worth considering when your lawn grows quickly or you want a consistently neat, freshly cut appearance.

Weekly mowing can be particularly useful for:

Summer Growth

December, January and February are typically peak mowing months across the Bay of Plenty.

Warm temperatures and suitable growing conditions can cause grass to grow rapidly, meaning two weeks between cuts may allow the lawn to get ahead of you. Lawnify’s seasonal schedule moves many properties to weekly mowing during the summer peak.

High-Visibility Lawns

If your front lawn is one of the first things visitors see, weekly mowing gives you a consistently maintained appearance.

This can be especially useful for:

  • Show homes

  • Properties being prepared for sale

  • Rental properties

  • Large front lawns

  • Businesses

  • Body corporate properties

Fast-Growing Grass

Different grass varieties grow at different speeds.

A lawn that grows quickly may need weekly mowing even when a neighbouring property is perfectly comfortable with a fortnightly schedule.

Trying to force a fast-growing lawn onto a fortnightly schedule can mean taking too much grass off during each visit.

When Fortnightly Mowing Is the Better Choice

For many homeowners, fortnightly mowing is the sweet spot.

It provides enough regular maintenance to keep the lawn looking tidy without paying for a visit every week when the grass doesn’t necessarily need it.

Fortnightly mowing works particularly well for:

  • Standard residential sections

  • Regularly maintained lawns

  • Properties with moderate growth

  • Homeowners who don’t need a show-home finish

  • Shaded lawns

  • Cooler periods of the year

Lawnify describes fortnightly mowing as the “sweet spot” for most Bay of Plenty sections, with the schedule adjusted as seasonal growth changes.

What About Winter?

This is where a fixed weekly-versus-fortnightly decision doesn’t always make sense.

Bay of Plenty lawns don’t grow at the same speed throughout the year.

During the warmer months, growth can be rapid. Through the colder winter period, growth slows considerably.

Lawnify’s typical regional mowing rhythm is:

  • December–February: Weekly

  • March–May: Fortnightly

  • June–August: Monthly

  • September–October: Fortnightly

  • November: Weekly

The exact timing can vary depending on your location, lawn type, shade, soil and weather conditions.

This seasonal approach can be more cost-effective than paying for weekly mowing throughout the entire year.

The Long-Term Cost Difference

Let’s compare two simple approaches.

Option 1: Weekly All Year

At a starting rate of $45 per visit:

52 visits × $45 = $2,340 per year

Option 2: Fortnightly All Year

At a starting rate of $50 per visit:

26 visits × $50 = $1,300 per year

That’s a difference of approximately:

$1,040 per year

Of course, these are examples based on starting prices rather than quotes. Larger lawns, difficult access, slopes and longer edges can change the actual cost.

But There’s an Even Better Approach

Instead of choosing one frequency and sticking to it all year, a seasonal mowing schedule can often provide the best balance between lawn appearance and cost.

For example:

Summer: Weekly
Autumn: Fortnightly
Winter: Monthly
Spring: Fortnightly
Late spring: Weekly

This means you’re not paying for weekly mowing when your lawn is barely growing, but you’re also not allowing rapid summer growth to turn into an overgrown lawn.

That’s the approach Lawnify uses for many properties across the Bay of Plenty.

Does Fortnightly Mowing Damage Your Lawn?

Not necessarily.

The important thing is how much grass is removed during each cut.

If a lawn becomes excessively long and you remove a large amount at once, it can place unnecessary stress on the grass.

Regular fortnightly mowing helps avoid this problem during periods when the lawn can comfortably handle the schedule.

During peak summer growth, however, weekly mowing may be better for some lawns.

The goal isn’t simply to mow as little as possible. The goal is to maintain the lawn without allowing it to become overgrown.

What Happens If You Skip a Mowing Visit?

If your lawn is growing slowly, skipping a visit may not cause much of a problem.

But during spring and summer, missing a scheduled cut can make a noticeable difference.

The longer grass becomes:

  • Harder to cut

  • More time-consuming

  • More likely to produce heavy clippings

  • More difficult to maintain at the correct height

  • More likely to require an overgrown first cut

In other words, saving $50 today can sometimes create a more expensive mowing job later.

So, Which Costs Less Long-Term?

For most homeowners, the answer is:

Fortnightly mowing costs less overall.

But weekly mowing can provide better value during periods of rapid growth because it prevents the lawn from becoming overgrown and keeps the grass consistently maintained.

The most cost-effective solution for many Bay of Plenty properties is therefore not weekly or fortnightly all year.

It’s a mowing schedule that changes with the season.

What We Recommend for Bay of Plenty Lawns

For a typical residential lawn, we’d generally recommend:

Summer: Weekly if growth is strong
Autumn: Fortnightly
Winter: Monthly where growth is slow
Spring: Fortnightly, moving to weekly as growth increases

Coastal properties such as Pāpāmoa can behave differently from inland areas, while places such as Te Puke and Ōmokoroa can have their own growth patterns. Soil, exposure, grass type and shade all matter.

That’s why the best mowing frequency is based on your lawn rather than a one-size-fits-all calendar.
