Lawn Care in Spring — Sydney Expert Guide
Get your Sydney lawn off to the best start this spring. Expert tips on fertilising, mowing, aeration and weed control for Australian grass types.
Spring is the most important season for Sydney lawn care. As temperatures rise from August through to November, warm-season grasses like buffalo, kikuyu and couch emerge from their winter semi-dormancy and enter an aggressive growth phase. The care decisions made in spring — fertilisation timing, aeration, weed control and mowing frequency — determine how the lawn performs right through summer and into autumn.
The biggest spring lawn care opportunity is fertilisation. Applying a quality slow-release fertiliser in September, just as growth accelerates, gives the lawn the nutrients it needs to establish a strong, dense canopy that resists weeds, tolerates summer heat and recovers from foot traffic. Miss this window and you will spend summer trying to catch up with a thin, patchy lawn.

Sydney Spring Lawn Care Checklist
August (Late Winter)
- Apply pre-emergent weed control for bindii and winter grass
- Light mow to tidy up any overgrowth from winter
- Check edges and redefine where needed
- Prepare fertiliser for September application
September (Early Spring)
- First spring fertilisation with balanced slow-release NPK
- Core aeration for compacted areas
- Increase mowing frequency to fortnightly
- Treat any remaining broadleaf weeds with selective herbicide
October (Mid Spring)
- Mowing every 1–2 weeks as growth accelerates
- Second fertiliser application if needed for slow-recovering areas
- Dethatch if thatch layer exceeds 25mm
- Begin regular watering schedule as weather warms
November (Late Spring)
- Mowing every 1–2 weeks — kikuyu may need weekly cuts
- Monitor for lawn grubs as soil warms
- Adjust irrigation for longer, drier days ahead
- Prepare for summer — check mower blade sharpness
Frequently Asked Questions
When does spring lawn care begin in Sydney?
In Sydney, spring lawn care should begin in September when soil temperatures start to rise above 15°C — the threshold at which most warm-season grasses (buffalo, kikuyu, couch) begin actively growing again. This is the ideal window to fertilise, aerate, address thatch build-up and increase mowing frequency. Getting the timing right in early spring sets up the lawn for a strong performance through summer.
Should I fertilise my lawn in spring in Sydney?
Yes — spring is the most important fertilising window for Sydney lawns. Apply a balanced slow-release fertiliser with nitrogen, phosphorus and potassium (NPK) in September or October, just as the grass enters active growth. A well-timed spring fertilisation stimulates strong, even green growth, improves drought resistance for summer, and helps the lawn outcompete weeds. Avoid applying fertiliser to dry, stressed grass — always water before and after application.
How often should I mow in spring in Sydney?
Once spring growth kicks in — typically from mid-September in Sydney — increase mowing frequency to every one to two weeks for buffalo and kikuyu lawns. Couch and zoysia may initially need less frequent cutting as they wake up more slowly. The key is to stay on top of growth and never remove more than one-third of the blade length in a single session. Letting a spring lawn get too long before the first mow is one of the most common causes of scalping.
Is spring the best time to aerate a Sydney lawn?
Spring is one of the two best windows for lawn aeration in Sydney — the other being early summer. Aerating in September to October, just as the lawn enters active growth, allows the grass to recover quickly from the aeration holes. The improved air and water penetration into the root zone means the lawn is in peak condition to respond to spring fertilisation and handle the summer heat ahead. We recommend annual core aeration for most Sydney lawns.
How do I get rid of weeds in my lawn in spring?
Spring is an effective time to treat broadleaf weeds (bindii, clover, dandelion) with a selective herbicide before they spread aggressively through summer. For bindii specifically, treat in late winter/early spring (August–September) before seed heads form. Kikuyu lawns can handle most broadleaf selective herbicides, but buffalo lawns require a buffalo-safe product. Always read the label carefully and water the lawn the day before application for best results.
