If you want to keep your lawn looking thick, green and healthy this summer, now’s the time to stop weeds before they appear. With a few simple lawn care steps and the right products, you can prevent weeds from invading and competing with your grass during the warmer months.
What is the best way to prevent weeds?
A pre-emergent herbicide is one of the most effective ways to prevent weeds in your lawn. These products work by targeting weed seeds as they germinate, stopping them before they break through the surface.
If you’ve dealt with summer weeds like Crowsfoot or Summer Grass, a pre-emergent can make all the difference.
Popular options include Oxafert and Oxafert Plus, both granular products that combine a pre-emergent herbicide with fertiliser — so your lawn gets nutrients while you protect it. If you prefer liquid products, Barricade Pre-Emergent is another excellent choice.
How a Thick, Healthy Lawn Helps Stop Weeds
A dense, thriving lawn naturally suppresses weeds. When grass is thick, it leaves little room for weed seeds to settle and grow. It also competes for sunlight, water, and nutrients — making it much harder for weeds to survive.
If your lawn is looking patchy or thin, focus on improving its density with consistent mowing, watering, and feeding. A strong lawn is your best defence against weeds and other summer lawn problems.
Why Regular Mowing Helps with Weed Control
Regular mowing doesn’t just improve your lawn’s appearance — it plays a key role in weed prevention. Lawns that are left too long can thin out or become stressed, leaving gaps for weeds to establish.
If weeds are already growing, mowing them before they seed will help weaken them and reduce future spread.
Tip: If weeds have already gone to seed, use a catcher on your mower to stop the seeds from spreading across your lawn.
While mowing won’t completely eliminate weeds, it’s an important step in maintaining a healthy, resilient lawn.
What to do if Weeds Have Already Appeared
If you’ve noticed weeds starting to grow, act quickly. The sooner you remove or treat them, the less chance they’ll have to spread.
For small patches of broadleaf weeds, hand weeding works well. For larger infestations, use a broadleaf herbicide designed for lawns.
Common weeds like Clover, Bindi, Oxalis and Cudweed can be treated with products such as All Purpose Weed Control.

Fertilising to Strengthen Your Lawn and Prevent Weeds
Fertilising is one of the best ways to boost lawn growth and help prevent weeds. A healthy, well-fed lawn grows thicker and stronger, leaving less space for weeds to establish.
A balanced fertiliser provides essential nutrients your soil might be lacking. Lawn Solutions Premium Fertiliser is a popular choice — it contains both fast and slow-release nutrients to feed your lawn immediately and for up to 12 weeks.

The Key to Weed-Free Summer Lawns
The secret to keeping weeds away is consistency. By combining pre-emergent herbicides, regular mowing, and seasonal fertilising, you can maintain a lush, green lawn all summer long — without the stress of battling unwanted weeds.
