Lawn care and fertilising in the Sutherland Shire
Updated October 2026
Mowing keeps a lawn tidy. Lawn care keeps it alive. Fertilising, weed control, aeration and patch repair are the difference between grass that merely gets cut and a lawn that stays thick, green and ahead of the weeds. In the Sutherland Shire that work revolves around three grasses: buffalo, couch and kikuyu, and each wants slightly different treatment.

What lawn care covers
Depending on what the lawn needs, a program can include:
- Fertilising on a seasonal schedule, typically spring and autumn at minimum
- Broadleaf weed control for bindii, clover, cudweed and dandelion
- Aerating compacted areas, common on the Shire's clay and sandy soils
- Top dressing and patch repair where grass has thinned or died
- Advice on watering and mowing height for your grass type
Weed and pest spraying is done by contractors who hold the NSW pesticide training qualification that commercial application requires. Ask to see it.
The grass type matters more here than most owners realise. Buffalo, the Shire's most common lawn, holds shade well but is sensitive to some common weed sprays, so products have to be chosen for it specifically. Couch loves sun and feeds hard but thins out in shade. Kikuyu grows almost too well, it recovers from anything, but it wants regular feeding to stay green rather than stalky. A contractor who works these lawns weekly will identify yours on sight and treat it accordingly.
When to feed a Shire lawn
The reliable windows are early spring, when buffalo, couch and kikuyu all wake up and respond fastest, and mid autumn, which sets the lawn up to hold colour through winter. A summer feed helps on sandy soils near the coast around Cronulla and Kurnell, where nutrients wash through quickly. Bindii control is a winter job: spray by late winter, before the seed heads set, or you spend summer pulling prickles out of feet.
Lawn care alongside mowing
Lawn care works best as an add-on to a regular mowing round rather than a standalone visit. The contractor already on your lawn each fortnight sees problems early, a fungal patch, an armyworm outbreak, compaction along the side path, and can deal with them before they spread.If the lawn has been scalped back from a jungle, give it a feed after the overgrown cut to speed the recovery, and if the whole garden needs resetting first, start with a garden clean-up.
Frequently asked questions
How often should I fertilise my lawn?
For most Shire lawns, twice a year, spring and autumn, is the sensible minimum, with a third feed in summer for couch and kikuyu or on sandy coastal soils. More than four feeds a year is rarely worth the money on a home lawn.
Can you get rid of bindii and clover without killing buffalo?
Yes, with buffalo-safe selective herbicides. In NSW, anyone applying herbicides or insecticides commercially must hold the required pesticide training qualification, so ask the contractor to confirm theirs when they quote. Timing matters too: bindii must be sprayed in winter before it seeds.
Why is my lawn thin and patchy even though it gets mowed?
Usually some mix of compaction, shade, hungry soil or scalping. Aeration, feeding and raising the mowing height fix most of it, and bare patches can be top dressed or returfed. The contractor who quotes will tell you which applies to your yard.
What does lawn care cost?
It is quoted per job on the lawn's size and what it needs. As guide pricing only, a feed or weed spray added to a mowing visit adds a modest amount, while a full renovation with aeration and top dressing is priced in its own right. See the cost guide for how pricing works.
