Have you been wanting to apply more than one product to your lawn, but have been unsure on what to apply first, or how long to wait in between applications? In this blog, we discuss what order you should apply products in.

When using products alongside each other, it is important to ensure you apply each as per the label instructions. Some products need to be watered in, other products need to be applied to a dry lawn, and others may need to be applied when there is no expected rainfall for a few hours after application so that the product can dry and absorb into the plant.
The specific application information can be found on your products label.
The answer to this question will differ depending on who you ask. Some prefer to apply fertiliser to your lawn first in order to give the lawn and weeds a bit of a growth spurt, then once the weeds have grown, apply the herbicide, usually about a week later to remove them. If growth is already strong, remove the weeds first, and then once they have gone, apply a fertiliser to boost the overall health of the lawn.

Generally, when using herbicides on your lawn, it is not recommended to mix them with other herbicides or lawn care products in the same knapsack. Some chemicals may clash with others, impacting the product’s efficacy.
If you are looking to treat weeds and apply other products simultaneously, we recommend using these products a few hours apart. This will allow the herbicide to dry and absorb into the leaf, before applying the next. It is important not to use the second product immediately after, as this may cause the first to wash off the plant before it can be absorbed.
When using herbicides always ensure you are following the application specifications.
Generally, you can apply products to help improve your lawn’s soil health, e.g. Lawn Soaker, and Lawn Kelper simultaneously.


Granular products are generally ok to apply at the same time. However, it is always best to check the products application instructions regarding irrigation are the same.
We recommend spreading each product out separately to ensure there is even coverage. After each product has been applied, then water in the granules.

*Please note, applying a granular fertiliser and Oxafert or Oxafert Plus together is not recommended. This is due to Oxafert and Oxafert Plus both having a fertiliser component. When used with a fertiliser, you can over-fertilise the lawn. If you are wanting to apply a fertiliser and an Oxafert product, it is best to wait 3 weeks between applications.

There are many factors to consider when applying multiple products to your lawn, but if you are in doubt, apply separately or consult with the product manufacturer for their specific advice.
