As a homeowner in Australia, having a lush and healthy lawn can be a point of pride. However, one of the biggest challenges in maintaining a beautiful lawn is dealing with weeds. Not only do they detract from the overall appearance of your lawn, but they can also compete with your grass for nutrients, sunlight, and water.
In this blog post, we will discuss common lawn weeds in Australia, how to get rid of them, and tips for maintaining a weed-free lawn for the most common types of grass found in Australia: Zoysia, Couch, and Buffalo.
Common Lawn Weeds in Australia
Before we dive into how to get rid of weeds in your lawn, let’s first take a look at some of the most common weeds in lawns that you may encounter in Australia.
Bindii, also known as jo-jo or Onehunga weed, is a low-growing weed that is most commonly found in warm and dry areas of Australia. It is an annual plant that produces small, prickly seeds that can be painful to step on. Bindii grows best in areas with sandy or well-draining soil and can survive in both full sun and partial shade. It has a rapid growth rate, and its seeds can germinate quickly, making it challenging to control.
Appearance: Bindii has small, fern-like leaves that grow in a rosette pattern close to the ground. It produces small, green flowers that eventually dry out and turn into prickly seed heads.
Clover is a common weed in Australian lawns, especially in cooler and wetter regions. It is a perennial plant that can be difficult to control once established. Clover prefers moist soil and can thrive in both full sun and partial shade. It has a moderate growth rate and can spread rapidly by both seeds and creeping stems.
Appearance: Clover has three leaves that are usually oval or heart-shaped, and it produces small, white or pink flowers that are clustered together at the top of the stems.
Capeweed is a low-growing weed that can form dense mats that choke out the grass. It is an annual plant that has yellow flowers and prefers well-draining soil. Capeweed grows best in areas with full sun and moderate moisture. It has a rapid growth rate and can spread quickly through seeds and creeping stems.
Appearance: Capeweed has round or oval-shaped leaves that are lobed and slightly hairy. It produces bright yellow flowers that are daisy-like and can grow up to 5cm in diameter.
Wintergrass is a type of annual grass that can quickly take over a lawn if left untreated. It prefers moist soil and can thrive in both full sun and partial shade. Wintergrass has a rapid growth rate and can produce large amounts of seeds, making it difficult to control.
Appearance: Wintergrass has narrow leaves that are light green in colour and can grow up to 30cm in length. It produces small, light-coloured seed heads that can be up to 15cm long.
Oxalis, also known as sourgrass, is a weed that has small yellow flowers and can quickly spread through underground bulbs. It prefers well-draining soil and can grow in both full sun and partial shade. Oxalis has a moderate growth rate and can spread rapidly by both seeds and bulbs.
Appearance: Oxalis has clover-like leaves that grow in clusters and produces small, bright yellow flowers that are trumpet-shaped. It has a distinctive sour smell when crushed.
How to Get Rid of Weeds in Your Lawn
Now that you are familiar with some of the most common lawn weeds in Australia, let’s discuss how to get rid of them. There are several methods for removing weeds from your lawn, including:
For small patches of weeds, hand pulling can be an effective method. Make sure to remove the entire root system to prevent the weed from regrowing.
There are both selective and non-selective herbicides available for treating weeds in your lawn. Selective herbicides are designed to target specific types of weeds without harming your grass, while non-selective herbicides will kill any plant they come in contact with. It’s important to choose a herbicide that is safe for use on your specific type of grass.
Regularly mowing your lawn can help to prevent weed growth by cutting off the tops of the weeds and preventing them from producing seeds.
Aerating your lawn can help to loosen compacted soil and promote healthy grass growth, making it more difficult for weeds to take hold.
Providing your lawn with the proper nutrients can help it to grow strong and healthy, making it more resistant to weed growth.
Tips for Maintaining a Weed-Free Lawn
In addition to removing weeds from your lawn, there are several steps you can take to prevent them from growing in the first place. Here are some tips for maintaining a weed-free lawn in Australia.
Regular Lawn Maintenance
Regularly mowing, watering, and fertilising your lawn can help it to grow strong and healthy, making it more difficult for weeds to take hold.
Proper Lawn Watering
Overwatering your lawn can create the perfect environment for weed growth, so make sure to only water your lawn when it needs it. It’s recommended to water your lawn deeply but infrequently to encourage deep root growth.
As mentioned earlier, lawn aeration can help to promote healthy grass growth and prevent weeds from taking hold.
There are several weed prevention products and practices that can help to prevent weed growth in your lawn. The products typically work by creating a barrier on the soil surface that prevents weed seeds from germinating.
Regular Lawn Inspections
Regularly inspecting your lawn for signs of weed growth can help you catch weeds early on before they have a chance to spread.
Proper Lawn Irrigation
It’s important to water your lawn at the right time of day to prevent weed growth. Watering your lawn in the morning can help it dry out quickly, preventing weed growth.
Remove Lawn Weeds Before They Seed
It’s important to remove weeds before they have a chance to produce seeds, as this will prevent them from spreading and taking over your lawn.
Applying a layer of mulch around trees, shrubs, and other areas of your lawn can help to prevent weed growth by blocking sunlight and preventing weed seeds from germinating.
Hire a Professional
If you’re having trouble maintaining a weed-free lawn, consider hiring a lawn care professional. They can provide you with expert advice and help you develop a lawn care plan that is tailored to your specific needs.
