Weed Warriors: Winning the Battle Against Lawn Invaders
Weeds have a habit of turning up where they are not invited. The good news is that controlling lawn weeds does not need to become a weekend-long battle. Regular checks, early treatment and a healthy lawn can help keep most invaders under control.
Your two best defences are simple: look for weeds regularly and keep your lawn well fed.
1. Check Your Lawn Regularly
On the weekend between mows, take a quick walk across the lawn and look for young weeds. They are generally easier to manage before they grow, flower and set seed.
A few scattered weeds may only need targeted treatment. If weeds are appearing across a larger part of the lawn, an all-over selective lawn treatment may be more practical. Always choose a product that lists both the weed and your lawn type on the label.
2. Keep Your Lawn Thick and Healthy
A well-fed lawn grows more strongly and leaves less open space for weeds to establish. For regular feeding, use Scotts Lawn Builder™ All Lawn Types Lawn Food according to the label directions.
Fertiliser will not kill an existing weed infestation, but supporting healthy, dense grass is an important part of long-term weed management.
Spot Treatment or Whole-Lawn Treatment?
For one or two weeds, use a lawn-safe selective spot treatment that lists the weed on its label. Avoid spraying surrounding garden plants, as selective lawn herbicides can still damage other broadleaf plants.
For weeds spread across the lawn, a hose-on treatment such as Scotts Lawn Builder Weed, Feed & Green Up Refillable Bottle may be more suitable. It targets listed broadleaf lawn weeds, including bindii and clover, while feeding, thickening and greening the lawn.
If you have a buffalo lawn, choose the buffalo-compatible Scotts Lawn Builder Buffalo Weed, Feed & Green Up Refillable Bottle and check the label for lawn-variety precautions before applying.
Can You Pull Lawn Weeds by Hand?
Hand weeding can work when there are only a few weeds, provided you remove the entire root system without scattering seeds.
Use a hand weeder or small trowel rather than simply pulling the leaves. Weeds with deep taproots or underground runners can regrow when part of the root remains in the soil. Remove weeds before they flower and place any seed heads straight into your green waste bin.
Common Cool-Season Lawn Weeds
Weed timing varies across Australia, particularly between warm northern areas and cooler southern regions. Instead of relying only on the calendar, check your lawn regularly and treat weeds while they are young and actively growing.
Clover
Clover can spread through thin or underfed sections of lawn. Treat it while it is actively growing and before it flowers and sets seed. Scotts Lawn Builder Weed, Feed & Green Up Refillable Bottle lists clover among its targeted weeds.
Follow treatment with a regular feeding routine to encourage stronger, denser lawn growth.
Bindii
Bindii commonly grows during the cooler months before producing the painful burrs noticed in warmer weather. Young bindii has low-growing, finely divided leaves that can look a little like miniature parsley.
Inspect the lawn through autumn and winter, and treat bindii before the seed heads harden. Scotts Lawn Builder Buffalo Weed, Feed & Green Up Refillable Bottle is an option for compatible buffalo lawns, while the standard refillable bottle is available for other compatible lawn types. Always check the label first.
Creeping Oxalis
Creeping oxalis can spread through creeping stems and small plant fragments, making careless hand removal difficult. Treat it while it is actively growing, before flowering and seed production.
Not every broadleaf lawn herbicide controls every type of oxalis. Confirm that creeping oxalis and your lawn variety are both listed on the product label before treatment.
Capeweed and Dandelion
Capeweed and dandelion can be difficult to pull because of their strong root systems. If hand weeding, loosen the soil and remove as much of the root as possible.
Treat young plants before they flower and spread seed. Where these weeds are scattered across the lawn, use a suitable selective spot treatment. For widespread infestations, choose a compatible whole-lawn treatment that specifically lists the target weed.
Keep Weeds on the Back Foot
There is no single treatment that suits every lawn or every weed. Identify the weed first, check your grass type and read the complete product label before applying any lawn treatment.
Once the existing weeds are under control, keep mowing at the right height, repair bare areas and maintain a regular feeding routine. A thick, healthy lawn is your best long-term defence against the next wave of party crashers.
