Bindi weeds are some of the most difficult weeds to get rid of in your backyard. They’re also so small you might miss them.
Even if you know they’re there, it can be a challenge to remove them. So, how do you get rid of bindi weeds?
How to identify Bindi weeds
To properly identify Bindi weeds, the first thing to look for is a rosette of leaves (ie, a whorl of leaves that radiate from a common point).
Also known as Soliva pterosperma, Bindi plants are small, growing to a maximum of 4 cm in diameter. The flowers are very tiny and greenish-yellow in colour. Bindis flowers in Autumn and Winter, maturing into seeds that grow during Spring and Summer.
The seed prickles are extremely sharp and make it unpleasant to walk barefoot on infested lawns.
Bindis can grow anywhere in your garden, including vegetable patches or lawns.
Options for getting rid of Bindi weeds
Removing by hand
If you’re happy with a more hands-on approach, your best option is to pull them out.
When the soil is moist and the bindi weeds are young and tender, they can be easily removed by hand using a trowel or weeding tool.
Ensure that you remove the roots of each plant so they can’t grow back.
The best time to attack these weeds is in spring before they start flowering and going to seed in October/November.
If you’re plagued with bindi weeds, then spraying is likely your best option.
There are great herbicides that target bindi weed without damaging your lawn, such as Yates Bindii Weed Control and Amgrow Bin-Die Concentrate.
According to The Department of Primary Industries, effective herbicides for Bindii treatment will contain bromoxynil plus MCPA.
Are there natural methods for removing Bindis?
- Vinegar is an effective method, but it can also be harmful to grass and other plants. Be sure to only remove bindis from areas where contact with the vinegar won’t kill other plants.
- Boiling hot water can burn bindis and kill them. Again, make sure that the area you are pouring boiling water on doesn’t contain any other plants or grass you don’t want killed.
- A natural herbicide will be able to control bindis without harming other plants and animals in your garden or lawn.
- If you have a large infestation of Bindis, hand-picking may be the best option for removing them from your patch of turf or garden beds.

How to prevent Bindis from growing
To prevent bindis from growing in your lawn, you’ll want to create the least favourable conditions possible.
Bindis thrive in full sun and hot, dry weather, so by keeping your lawn healthy and strong, you can keep them out of the picture.
Here are some tips:
- Feed your lawn regularly with a balanced fertilizer
- Mow regularly to keep your lawn at a good height
- Regularly remove weeds
- Make sure your lawn gets enough water
With regular mowing, feeding, and watering, you can create an ideal environment for grass and an unfavourable one for pesky bindis.
When is the best time to spray Bindis?
The best time to spray Bindis is on warm and dry days, when temperatures are above 10 degrees and below 30 degrees.
This allows the herbicide to be absorbed by the weed before it can evaporate or be washed off by rain, sprinklers or heavy dew.
The ideal conditions for treating weeds and grasses with herbicides include morning or late afternoon light breezes, low humidity, a slight moisture in the soil, and plants that are not under drought stress. This will ensure maximum uptake of the herbicide by the target plant.
