Buying Guide

Things You Need to Consider

Having the best weed killer in Australia lets you maintain the beauty of your lawn and keep pathways or driveways clean from weeds.

But picking the right one demands a bit of homework as there are a lot more options, depending upon its functionality, to control a variety of weeds in different situations. Here are some critical factors that you have to consider for a beneficial purchase.

1. Identify Your Weeds

Before buying a weed killer, the most important thing to consider is to identify the weeds you want to target, whether broadleafs or turfy weeds. Then you can move further as there are selective weed killers available in the market.

These are manufactured to destroy specific types of weeds, such as chickweeds, without affecting any other plant.

If you buy a product that doesn’t have an active constituent to kill the target weeds, then it will be useless to use, or it can harm the grass. Moreover, you have to choose between a contact, systemic or residual weed killer, depending on the target weeds.

2. Where Can It Be Used?

Whether you want to use a weed killer to kill weeds in your lawn, buffalo grass, or those sprouting from the cracks. Depending on it, you have to choose a selective or non-selective weed killer. Selective weed killers target specific weeds and inhibit their growth without affecting grass or any other plants around them. 

In contrast, non-selective weed killers destroy every weed or plant that comes in contact with it. So selective weed killers are the best options when it comes to choosing one for a grassy lawn. While for cracks and clearing a patch, you can use non-selective weed killer.

Also, you can use a gas torch weed killer to clear small patches of greenery by burning them. But this is only suitable when you have to get rid of weeds in a small lawn or from concrete pathways and patios.

3. When to Use a Weed Killer?

You need to consider the time of usage of a weed killer. You can use a weed killer once or twice a year to combat annual and perennial weeds. If you want to, you have to use pre-emergent weed killers that inhibit the growth of buds and prevent them from emerging as grown weeds. You can apply these weed killers as a lawn care strategy at the start of spring.

But if weeds are already grown, and you want to destroy them, you have to pick the post-emergent weed killers. They destroy the weeds, either by dehydrating them or affecting the root system bu entering into plants.

Some of the best weed killers in Australia are dual-acting, kill the present weeds and prevent the emergence of new weeds in returning season.

4. How much Coverage it Offers?

How much coverage can a bottle of weed killer offer? You have to check it by keeping in mind the size of your lawn or the overgrown area you want to clear.

Most of the mid-range weed killers offer an average of 1,000 square feet of coverage. In comparison, some of the expensive weed killers can effectively clean up to 10,000 square feet of lawn. 

If your lawn has a large area to cover, be ready to spend a little more. Also, you can choose to concentrate weed killers as these can be diluted to make a large number of solutions, ensuring more coverage.

It is best to have a weed killer with a decent quantity that allows you to use it multiple times and not every time you have to buy a new one.

5. Check the Safety of Usage

To ensure the safety of kids and pets, as well as other edible plants, you have to check the active constituents of the weed killer you want to buy. These can be either organic, natural ingredients, or synthetic chemicals.

Also, residual weed killers have toxic ingredients that stay longer in soil, and you have to keep this in mind while using them.

The weed killers that have Safer Product labels are safer to use around kids and pets. But if you use any weed killer with a warning label like Danger or Poison, you have to be extra careful, or it is better to avoid such products for the home lawn.

Moreover, gas torch weed killers are environment-friendly and do not have such harmful effects.


How often should you use a weed killer?

Usually, a weed killer is applied once or twice a year to eradicate weeds, depending on annual or perennial weeds. Although, some stubborn weeds need to be sprayed after every two weeks unless the weeds wither entirely.

What weed killer kills everything including grass?

Weed killers that have glyphosate as an active ingredient kill everything that comes in contact with it, including grass. So you have to be careful using such weed killers as they can damage the grass of your lawn.


Whether you want to maintain the good looks of your lawn or want to renovate overgrown areas, you need the best weed killer in Australia to get rid of all unwanted plants. For this, you must have a bit of knowledge of weeds, grasses, and chemical products to pick the right option for you, as there are a variety of weeds that grow in Australia and products available in the market to kill them.
