Weed Control Tips

Australia’s native weeds can be classified into two different kinds: grass weeds and broadleaf weeds. Telling them apart is fairly straightforward: broadleaf leaves resemble a plant, whereas grass weeds might bear more resemblance to your lawn.

Grass Weeds

If you stumble across a grass-shaped imposter, check for any fibrous roots and the absence of a leaf stalk. If it fits this criterion, you are likely looking at a grass weed. Crabgrass, nutgrass and summer grass all fall into this category. In small quantities, the best way to remove them is generally by hand, but if you want to save yourself some time, try spraying your lawn with a post-emergent herbicide. You can avoid them from popping up again with the use of a pre-emergent pesticide mid-spring, which will terminate the seeds’ germination.

Removing Broadleaf weeds

Broadleaf Weeds

If the weed you have encountered has leaves made up of a blade and a leaf stalk, and has a root system, you are dealing with a broadleaf weed. Common Australian weeds that fit these criteria include oxalis, thistle, chickweed, dandelion and lamb’s tongue. Whilst these can be pulled by hand, a selective herbicide is a faster, more convenient alternative which will target the source of these unsightly weeds whilst not affecting your lawn.

1. Mow Your Grass Shorter

To prevent new growth from seeds that may have been left behind by the previous season’s pollination, mow your grass at least once a week during warm weather months. The longer your grass is left untrimmed, the longer you are giving the accompanying weeds permission to freely sprout again after you have spent hours of your precious time trying to remove them.

2. Use The Appropriate Chemical Herbicide

There are different types of chemicals available for specific weeds. Whilst a pre-emergent herbicide prevents weeds from appearing, a post-emergent herbicide targets those that have already grown. Non-selective herbicides will kill any plant they touch, which is a good option if you regularly deal with many different types of weeds. Make sure you know what chemical is right for your type of weed and its intended purpose before applying it to your lawn and remember to carefully measure the surface area to be covered when mixing a herbicide together.

3. Remove Weeds By Hand

The simplest and most environmentally-friendly way of removal, most weeds can be pulled from the ground with a weeding tool or your hands. This is not only more effective but also more economical than using expensive machines that can tear up your lawn.
