How Often Should You Mow Your Lawn in Melbourne?
In Melbourne, the “four seasons in one day” weather means you can’t stick to the same mowing schedule year-round. While your Kikuyu might grow an inch a day in November, it will barely move in July. Adjusting your frequency is the secret to a healthy, weed-free lawn. To maintain a professional look, your mowing frequency should follow how quickly the grass grows, not a set schedule to mow the lawn.
1. Spring (September – November): Every 7 to 10 Days
This is the “danger zone” for Melbourne lawns. As soil temperatures rise and the spring rains hit, varieties like Kikuyu and Couch go into overdrive, meaning you’ll need to regularly cut and mow lawn areas to keep up.
- Why: Mowing weekly prevents the grass from becoming “stemmy” and ensures you don’t break the one-third rule (never cutting more than 1/3 of the blade height).
- Pro Tip: If you miss a week in October, do two high-clearing mows three days apart rather than one scalp-level cut.
2. Summer (December – February): Every 10 to 14 Days
Melbourne’s dry heat can actually slow down grass growth as the plant tries to conserve energy. However, mowing your lawn is still necessary, just less frequently during summer. In fact, the heat can make it harder to mow lawn areas, so plan accordingly.
- Why: You want to leave the grass slightly longer (around 40-50mm) to shade the soil and roots from scorching 40-degree days.
- Adjustment: If Melbourne is experiencing a heatwave or “total fire ban” conditions, skip mowing entirely until the temperature drops.
3. Autumn (March – May): Every 14 to 21 Days
As the air cools, growth slows down, but the lawn is still active enough that it needs to be mowed. Keeping up with your plan to mow the lawn helps prepare your garden for winter.
- Why: This is the best time to maintain a tidy height before the lawn enters winter dormancy. Regular mowing in autumn also helps clear fallen leaves that can trap moisture and cause fungal issues.
4. Winter (June – August): Every 4 to 6 Weeks (Or Not at All)
In Melbourne’s frost-prone suburbs like Dandenong or Yarra Glen, warm-season grasses like Sir Walter Buffalo will go dormant. But if you have a cool-season lawn, you may need to mow lawn areas, even in winter.
- Why: Mowing dormant grass can cause permanent damage. Only mow if you have a “cool-season” lawn like Tall Fescue or to trim back weeds that thrive in the cold.
- Rule of Thumb: If it’s not growing, don’t mow it.
Mowing Frequency by Grass Type
| Grass Variety | Peak Season Frequency | Off-Season Frequency |
|---|---|---|
| Kikuyu | 7 Days | 21 – 30 Days |
| Buffalo | 10 – 14 Days | 30+ Days |
| Couch | 7 – 10 Days | Dormant (Don’t Mow) |
| Tall Fescue | 7 – 10 Days | 14 – 21 Days |
The “Golden Rule” for Melbourne Gardeners
Always check the forecast before you pull the cord. Mowing wet grass in a Melbourne downpour will clog your mower and tear the roots, leading to a patchy, uneven finish. Wait for a dry window to ensure a clean, healthy cut, and remember it’s safest and easiest to mow lawn surfaces when conditions are dry.
