A Healthy Lawn Starts with the Right Care: Your Guide to Feeding, Weeds and Pests

Key Takeaways

• Lawns need regular feeding with a fertiliser suited to leaf greening, not just water and sunshine, to maintain strong root and leaf growth.
• Dead or brown patches that lift away easily are often a sign of lawn grubs rather than dry weather, and are best treated quickly before they spread.
• Bindii and clover are two of the most common lawn weeds in Australia and are best treated with a selective herbicide before they set seed.
• Mullumbimby couch and other broadleaf weeds need a different, broader-spectrum weed control approach than bindii and clover alone.
• Not every lawn treatment suits every grass type, so always check whether your product is safe for buffalo, couch, kikuyu or fescue before applying.

Feed Your Lawn for Deep, Green Growth

Just like any other plant, your lawn needs regular feeding to stay thick and healthy, particularly through its active growing months. A dedicated lawn fertiliser such as Searles Lawn Food combines organic and inorganic ingredients with added iron to promote deep green colour and strong root development. It's formulated to suit all lawn types, including buffalo varieties like Sir Walter and Palmetto, so it's a straightforward option no matter what's growing in your yard.

‍

Dead Patches Could Mean Lawn Grubs

If you've noticed dead or brown patches appearing in your lawn that lift away from the soil in clumps, lawn grubs are often the culprit. Pests such as lawn armyworm and African black beetle larvae feed on grass and its roots, and activity tends to ramp up from late spring through summer and into autumn. A granular treatment like Searles Dead Grub Pro For Lawns uses bifenthrin to quickly bring an infestation under control, and because it's broad-spectrum, it works against a range of common lawn grubs and beetles rather than just one species.

‍

Treating Bindii and Clover Before They Take Hold

Bindii and clover are two of the most familiar lawn weeds for Australian households, and both are easiest to manage while they're small. A selective herbicide such as Searles Bindii & Clover for Lawns is designed specifically to target these weeds, along with others like dandelion, chickweed and creeping oxalis, without harming lawns such as couch, fescue, carpet and ryegrass. Treating in autumn or spring, before weeds set seed, generally gives the best results.

‍

Dealing with Mullumbimby Couch and Broadleaf Weeds

Sometimes a lawn's weed problem goes beyond bindii and clover. Mullumbimby couch and other broadleaf weeds can quickly take over if left unchecked, and they call for a different herbicide blend. Searles Lawnweeder Selective Weed Killer combines three active ingredients to control Mullumbimby couch alongside weeds like dock, dandelion and sowthistle, and it's suited to couch, kikuyu, carpet and fescue lawns. It's worth noting this product isn't recommended for buffalo lawns or Queensland Blue Couch, so always check the label against your grass type before spraying.

Keep Up the Basics: Watering, Mowing and Aerating

Beyond feeding and weed control, a few simple habits make a real difference to overall lawn health. Watering deeply but less often encourages roots to grow further into the soil. If you notice the water running off the surface instead of soaking in, your lawn may have become hydrophobic. A single application of Penetraide can help restore water penetration for up to 12 months. Mowing high and removing no more than a third of the grass blade at a time helps prevent stress on the turf. Aerating compacted soil with a garden fork also allows water, air and nutrients to reach the root zone more easily. You can find more seasonal advice like this on the Searles Lawn Care hub, which covers everything from top dressing to pest watch-outs.

Conclusion

A great lawn doesn't happen by accident, it comes down to consistent feeding, early weed control and keeping an eye out for pests before they cause lasting damage. Whether your lawn needs a feed, a weed treatment or a grub clean-up, matching the right product to the job makes all the difference. No matter where you are in Australia, you can find the Searles lawn range at your local garden centre. Find your closest stockist through our Where to Buy page and get your lawn sorted this season.

FAQs

How do I know if my lawn has grubs or is just dry?

‍
Dry patches usually feel firm and the grass stays rooted, while grub damage often lifts away from the soil easily in clumps because the roots have been eaten through.

‍

Can I use the same weed killer for bindii and Mullumbimby couch?

‍
Not always. Bindii and clover are typically treated with a targeted herbicide, while Mullumbimby couch and other broadleaf weeds need a broader-spectrum product like Searles Lawnweeder.

‍

Is Searles Lawn Food safe for buffalo lawns?

‍
Yes, Searles Lawn Food is suitable for all lawn types, including buffalo varieties such as Sir Walter and Palmetto.

‍

When is the best time to treat lawn weeds?

‍
Autumn and spring are generally the best times, treating weeds while they're small and before they set seed for the following season.
