HOW TO USE LAWN WEED KILLER

When using lawn weed killer, you want to ensure that you get the maximum impact from it each time and there is a limit to the frequency of its use. So, when applying the treatment, you want to ensure you give it every chance to kill the whole weed and it is removed fully.

BE CAREFUL:

Make sure that you use lawn weed killer and not normal weed killer on a lawn

Take a read of the steps to follow below:

1. Plan the Timing

You want to ensure you are applying it at the correct time, so check out the guide on when to use a lawn weed killer. A summary of these are:

• Only apply between April and September
• Ensure the weather is dry and not windy
• Apply after mowing your lawn and leave it until mowing again

2. Apply the Weed Killer

Your weed killer will be applied via a spray bottle, either in a ready to use spray bottle or mixed from concentrate and then applied from a separate sprayer. For guidance on which sprayer to use, check out the buying guide.

When spraying the weed killer, you want to be specifically targeting the centre of each weed rather than generally covering the whole lawn, so that you maximise the effect of the lawn weed killer and have a minimal effect on the lawn. To do this, you want to get close to the weed - roughly 15-20cm away. 

You will normally aim to provide no more than 2-3 sprays per weed, which should result in the weed appearing to be wet but not to the extent that this starts to run off of the weed. 

3. Leave it

This bit is easy - leave it alone to kill the weed! You will start to see the weed change colour - from green to black, as it dies. You may start to see this happening within a day, but this process may take up to a week for it to fully die. 

Whilst it dies, you want to avoid mowing the lawn for as long as possible (3-4 days as a minimum), so that you can ensure that the lawn weed killer is fully absorbed and the whole weed is killed.

4. Rake it

Now that the weed is dead, you want to attempt to remove this dead matter to prevent the weed re-growing or spreading its seed. To do this, you want to rake or scarify the lawn and pull that dead material out.

5. Mow it

Once raked, the dead material will be sitting on top of the lawn and needs to be collected. So, by mowing the lawn, you will be able to easily collect the dead weeds and prevent them from contaminating the lawn. By mowing, this will also cut out any dead weeds that are not removed from the raking. 

Once you have mowed the lawn, be sure to carefully dispose of this dead material and do not place it within a composter or use it for mulching. 

6. Re-seeding

Depending on the extent and size of the weeds, you may find that you now have gaps in your lawn. If you fail to re-seed, your lawn will be looking rather sparse and there is a high probability that the weeds will return in those gaps. So to prevent this, you will want to re-seed those spots.
