How Often Should You Mow Your Lawn?

The complete guide to mowing frequency in Melbourne.

Mowing Guide

Finding Your Perfect Mowing Schedule

One of the most common questions homeowners ask is "how often should I mow?" The answer depends on several factors: your grass type, the season, recent weather, and whether you're fertilizing. Getting the frequency right is crucial - mow too often and you stress the grass; too infrequently and you're forced to remove too much at once.

The golden rule is simple: never remove more than one-third of the grass blade length in a single mow. This single principle will guide most of your mowing decisions throughout the year.

By Grass Type

Mowing Frequency by Species

Different grasses have different growth rates

ðŸ¦˜

Buffalo Grass

Peak Season: Every 10-14 days

Winter: Every 4-6 weeks

Buffalo is a slower-growing grass, making it lower maintenance than other varieties. In summer, the broad leaves grow steadily but not aggressively.

ðŸŒ¿

Kikuyu Grass

Peak Season: Every 5-7 days

Winter: Every 2-3 weeks

Kikuyu is the fastest-growing lawn grass in Melbourne. During warm weather with adequate moisture, weekly mowing is often necessary to keep up.

✨

Couch Grass

Peak Season: Every 7-10 days

Winter: Every 3-4 weeks

Couch is a vigorous grower but slightly less aggressive than Kikuyu. It rewards frequent mowing with a dense, carpet-like appearance.

Seasonal Guide

Mowing Frequency by Season

Adjust your schedule as conditions change

ðŸŒ¸

Spring (Sep-Nov)

Growth accelerates rapidly. Start with fortnightly mowing in September, increasing to weekly by November. This is the most active growth period - stay on top of it or you'll be playing catch-up all season.

☀️

Summer (Dec-Feb)

Maintain weekly mowing for Kikuyu and Couch; 10-14 days for Buffalo. During extreme heat or drought, growth slows significantly - you may skip a mow. Raise cutting height to reduce stress.

ðŸ‚

Autumn (Mar-May)

Growth gradually slows. Reduce frequency to every 10-14 days by April, moving to fortnightly by May. Lower cutting height slightly in preparation for winter.

❄️

Winter (Jun-Aug)

Minimal growth - mow only as needed, typically every 3-6 weeks. Some months you may not mow at all. Never mow frozen or waterlogged grass. Maintain regular height.

Pro Tips

Signs You Need to Mow

Rather than sticking to a rigid schedule, experienced lawn owners learn to read their grass. Here are the signs that it's time to mow:

1. The One-Third Rule Check

If your grass has grown 50% taller than your target height, it's time. For example, if you maintain Buffalo at 40mm, mow when it reaches 60mm. This ensures you're only removing one-third of the blade.

2. Grass Looking Shaggy

When your lawn loses its neat appearance and blades start falling over or looking uneven, it's overdue. Acting quickly prevents the "scalped" look that comes from removing too much at once.

3. Seed Heads Forming

If you see seed heads developing, your grass is getting too long. Regular mowing prevents this and directs the plant's energy into lateral growth rather than seed production.

4. After Rain + Warmth

Warm weather combined with recent rain triggers rapid growth. You may need to mow 2-3 days earlier than planned after these conditions.

Common Questions

Mowing Frequency FAQs

Answers to common mowing questions

You can, but there's usually no need. Warm-season grasses grow minimally in winter. Mowing without sufficient growth can damage the crown and thin the lawn. Only mow when the grass has clearly grown - typically every 3-6 weeks.

Don't try to cut it all back at once. Remove one-third of the height, wait 3-4 days, then mow again. Continue until you reach your target height. Removing too much at once shocks the grass and can cause yellowing or die-off.

Wait at least a week after fertilizing before mowing, as the grass will experience a growth surge. Then be prepared to mow more frequently for the next 2-4 weeks as the fertilizer takes effect.

Yes! Regular mowing encourages lateral growth (tillering) rather than upward growth. This creates a denser, more carpet-like lawn. Infrequent mowing results in sparse, leggy grass.
