Pre-emergent herbicides are fantastic products to add to your lawn care regime. With these herbicides, your application timing can impact how well it will work to prevent weeds in your lawn.
In this video, we look at the optimal times throughout the year to apply a pre-emergent to get the best results.
How Does a Pre-Emergent Work?
Pre-emergents work by targeting weed seedlings during germination. They create a barrier at the soil level that affects the germination of any new seedlings. This means they will target weeds before they appear but will not be effective after weeds have started growing.
Why Should I Time My Application?
As pre-emergents work by targeting weeds before they appear, you will need to time your application just before weeds are set to start growing in your lawn. If you can create the barrier at the soil level before the weeds are set to start growing, you can stop them during their germination phase.
When Should I Apply a Pre-Emergent for Seasonal Winter Weeds?
Pre-emergents can also be used to help prevent seasonal winter weeds, including Winter Grass. Seasonal winter weeds will start to germinate once the average soil temperatures start to drop below approximately 14 degrees. Therefore, it is best to get your application on just before this is set to occur. The exact time this will occur will depend on your location and temperatures in your region. As a guide, this will usually happen around mid to late autumn.
When to Apply a Pre-Emergent for Seasonal Summer Weeds?
Some seasonal summer weeds that pre-emergents will help target include Summer Grass, Crabgrass, and Crowsfoot. Seasonal summer weeds will start to germinate when the soil temperatures begin to warm back up, usually when the average soil temperature is above approximately 14 degrees. So, it is best to get your application down before the temperatures are set to rise in your region. The exact time for your application will change depending on your location and temperatures in your region. As a guide, this will usually occur around early to mid-spring.
What Pre-Emergent Should I Use?
When it comes to using pre-emergents, we recommend using our Lawn Solutions Oxafert Pre-Emergent Herbicide and Fertiliser. Oxafert comes in a handy 3kg bag that will treat up to 100m2 and is safe for most warm season turf types. Oxafert will remain active for up to 12 weeks, for protection of seasonal weeds.
Oxafert also comes in a 20kg bag, with the addition of an insecticide, called Oxafert Plus. This is great combination product to utilise and makes weeds prevention, fertilising and pest treatment easier than ever.
If you would prefer to use a liquid, Barricade is another great option with a high level of effectiveness for preventing a broad range of invading weed species, also available online the Lawn Store.
